694918715What are the four forms of viral genomes?double stranded DNA, single stranded RNA, single stranded DNA, double stranded RNA
694918716What is a capsid?protein shell enclosing viral genome capsids shape may be rod-shaped, polyhedral or more complex
694918717What is a capsomere?protein subunits that build capsids.
694918718What are the components of the viral envelope?1.Host cell phospholipids and membrane proteins derived from membranes of the host cell. 2. proteins and glycoprotiens derived from viral origin.
694918719what is the role of the envelope in animal viruses?glycoproteins which the cells of animals receive and allow entrance in membrane
694918720What property of viruses determines its attachment to a host cell membrane?glycoproteins. between viral surface proteins and specific receptor molecules on the outside of the cell
694918721viruses are obligate intracellular parasites. what does this mean?viruses have to function by invading and living in cells
694918722what is meant by host range?extra particular virus can infect cells of only a limited number of species. ex: west nile has a broad host range... can infect insects, humans ex: measles have limited host range.. can only affect humans
694918723What components of the host cell does a virus use to reproduce itself?nucleotides, enzymes, ribosomes, RNA, amino acids, and ATP
694918724How does a DNA virus reproduce its genome?DNA polymerase
694918725How do most RNA viruses replicate their genome?Virally encoded RNA polymerase
694918726What are bacteriophages?A virus that infects a BACTERIA
694918727Distinguish between a virulent and temperate phagesV- replicates only by lytic cycle T-uses lysogenic and lytic cycle to reproduce
694918728What portion of a phage enters the host cell? how does it do this?Binds glycoprotein to receptor of host cell DNA
694918729What are restriction enzymes? How do they prevent viral infections of bacteria?metholate DNA in a resistant/restrictive way
694918730Why don't restriction enzymes destroy the DNA of the bacterial cells that produce them?evolution. instead of lysing their host cells, many phages coesixt with them in a state called lysogeny
694918731what are three ways bacteria may win the battle against the phages?1. evolution 2. lysogeny 3. restriction enzymes
694918732What is a prophage?when integrated into the bacterial chromosome, the viral DNA is known as a prophage. one prophage gene codes for a protein that prevents transcriptions of most of the other prophage genes
694918733Describe the lytic mode of bacteriophage reproductionlytic cycle- phage replicative cycle that cumulates in death of the host cell. Each can infect healthy cell. LASt stage of infection
694918734Describe the lysogenic mode of bacteriophage reproductionlysogenic cycle- allows replication of the phage genome without destroying the host
694918735what are 2 elements that nearly all animal viruses have?1. RNA genome have an envelope 2. Replicate in host cells
694918736What is a retrovirus?equipped with an enzyme called reverse transcriptase which transcribes an RNA template into DNA, providing an RNA---> DNA information flow, opposite of the usual direction.
694918737How does HIV replicate their genome?After HIV enters the host cell, its reverse transcriptase molecules are released into the cytoplasm, where they catalyze synthesis of viral DNA. Newly made viral DNA then enters the cell nucleus and interprets into the DNA of a chromosome. Provirus never leaves cell.
694918738Compare and contrast provirus and prophageprophage leaves the cell. provirus never leaves the cell
694918739Plasmidssmall circular DNA molecules found in bacteria and yeast. Exist apart from cells genome replicate independently from genome transferred between cells

694918741What are 3 ways that viruses make us ill?1. Damage/kill cells causing release of hydrolytic enzymes from lysosomes 2. cause infected cells to produce toxins 3. molecular components that are toxic, such as envelope proteins provirus affects mature cells. cells don't divide and can't be replaced
694918742What contribute to the sudden emergence of genes?1. mutation of existing viruses 2. Solution is isolated in human population 3. Spread of existing viruses from other animals
694918743Horizontal transmissionPlants infected from external source

694918745How do viruses spread throughout plant bodies?plasmodestata-cytoplasm and connections that penetrate the walls between adjacent plant cells
694918746What is a viroid?plant pathogen consisting of a molecule of naked, circular RNA a few hundred nucleotides long. A single molecule can be an infectious agent that spreads a disease. Ex: Mad cow
694918747Prionsinfectious proteins that cause brain disease in animal species transmitted through food incubation period of at least ten years before symptoms develop virtually.
694918748Operon modelcontrols gene expression in bacteria
694918749Operatorthe regulatory "switch"; a segment of DNA positioned within the promoter
694918750Operonthe entire stretch of DNA; includes the operator, the promoter, and the genes that they control
694918751Negative Operon controlgene that is normally on is turned off
694918752Positive Operon controlgene that is normally off is turned on
694918753What type of operon control do the regulation of the trp and lac operons involve?Negative control, because operons are switched off by the active form of the repressor
694918754repressible operonnormally on; binding of a repressor to the operator shuts off transcription (trp operon)
694918755Inducible operonnormally off; an inducer inactivates the repressor and turns on transcription (lac operon)
694918756Repressible enzymesfunction in anabolic pathways; their synthesis is repressed by high levels of the end product
694918757Inducible enzymesfunction in catabolic pathways; their synthesis is induced by a chemical signal
694918758What protein is an activator of transcription, and subjects operons to positive control?Catabolite Activator Protein (CAP)
694918759What is the preferred food source of E. Coli?Glucose
694918760When glucose in E. Coli is scarce, what is activated by binding with cyclic AMP?CAP
694918761When CAP attaches to the promoter of the lac operon, what occurs?the affinity of RNA polymerase is increased, which accelerates transcription
694918762What happens in E. Coli when glucose levels increase?CAP detaches from the lac operon, and transcription returns to a normal rate
694918763What is the purpose of CAP?helps regulate other operons that encode enzymes used in catabolic pathways
694918764A Repressor is a product of what?a separate regulatory gene
694918765Why can't transcription factors bind to a promote packaged in a nucleosome?Nucleosomes block promoters
694918766Basal transcription factorsprovide alignment for RNA polymerase; establish productive initiation
694918767Specific transcription factors (activators)stimulate higher levels of transcription that basal levels
694918768Enhancersbinding site of specific transcription factors; DNA bends to form a loop, positioning the enhancer close to the promoter
694918769Three stages of embryonic developmentcell division, cell differentiation, and morphogenesis
694918770Cell differentiationthe process by which cells become specialized in structure and function
694918771Morphogenesisthe physical processes that give an organism its shape
694918772Cytoplasmic determinantsThe maternal substances in the egg that influence the course of early development by regulating the expression of genes that affect the developmental fate of cells.
694918773Inductionsignal molecules form embryonic cells cause transcriptional changes in nearby target cells
694918774Cell determinationcommits a cell to its final fate; before cell differentiation
694918775MyoDone of several "master regulatory genes" that produce proteins that commit the cell to becoming skeletal muscle; transcription factor that binds to enhancers of various target genes
694918776Pattern formationdevelopment of a spatial organization of tissues and organs (body plan)

694918778Maternal effect genesencode for cytoplasmic determinants that initially establish the axes of the body of Drosophila
694918779egg-polarity genesAnother name for maternal effect genes, these genes control the orientation (polarity) of the egg and the fly
694918780bicoidA maternal effect gene that codes for a protein responsible for specifying the anterior end in Drosophila.
694918781Three ways proto-oncogenes can be changed into oncogenesMovement of DNA within the genome, Amplification of a proto-oncogene, point mutations
694918782Movement of DNA within the genome causes?if it ends up near an active promoter, transcription may increase
694918783Amplification causes?increases the number of copies of the gene
694918784Point mutations cause?an increase in gene expression

550989921VerdunA battle in WWI. Is considered some of the bloodiest fighting in WWI and the German offense was stopped; offensive battle on the western front initiated by Germany in which they hoped to crush France and taken them out of the war, however France was in a very good defensive position and French held it for 10 months. Nearly a million killed. French drew reserve troops from the Somme to help defend. No territory was gained; Battle in WWI that ended in massive casualties and had little direct result
550989922SommeA five-month offensive between July and November 1916 in the Somme river area in France. It began with a massive week-long British artillery barrage that proved futile, since the Germans just sheltered in their dug-outs until the shelling stopped, then machine-gunned waves of British troops who were crossing no-man's land. On the first day alone the British lost 60,000 men. The battle ended in a stalemate, after torrential rain turned the trenches into a quagmire. There were more than 650,000 casualties on both sides, and although British had relieved the French at Verdun, they had only advanced about five miles.

629578931TRUE or FALSE: The majority of old people (past 65 years) have Alzheimer's disease.FALSE. Almost 90% of people who are 65 years of age do NOT have Alzheimer's Disease.
629578932TRUE or FALSE: As people grow older, their intelligence declines significantly.FALSE. Although there are some circumstances where the statement may hold true, current researchevidence suggests that intellectual performance in healthy individuals holds up well into old age. The average magnitude of intellectual decline is typically small in the 60s and 70s and is probably of little significance for competent behavior. There is more average decline for most abilities observed once the 80s are reached, although even in this age range there are substantial individual differences. Little or no decline appears to be associated with being free of cardiovascular disease, little decline in perceptual speed, at least average socioeconomic status, a stimulating and engaged lifestyle, and having flexible attitudes and behaviors at mid-life. The good news is that research data now indicate that intellectual decline can be modified by modest interventions.
629578933TRUE or FALSE: It is very difficult for older adults to learn new things.FALSE. Although learning performance tends on average to decline with age, all age groups can learn. Research studies have shown that learning performances can be improved with instructions and practice, EXTRA TIME to learn information or skills, and relevance of the learning task to interests and expertise. It is well established that those who REGULARLY PRACTICE their learning skills maintain their learning efficiency over their life span.
629578934TRUE or FALSE: Personality changes with age.FALSE. Personality remains consistent in men and women throughout life. Personality impacts roles and life satisfaction. Particular traits in youth and middle age will not only PERSIST but may be MORE PRONOUNCED in later life.
629578935TRUE or FALSE: Memory loss is a normal part of aging.TRUE. As one ages there is modest memory loss, primarily SHORT-term memory (recent events). Older adults are more likely to retain past or new information that is based on knowledge acquired or builds upon their life course or events. Retrieval of information may slow with age. The causes of these changes are unknown, but may include stress, loss, physical disease, medication effects and depression. Lack of attention, fatigue, hearing loss, misunderstanding are among factors impacting memory loss in persons of all ages. Strategies such as activity and exercise, association,visualization, environmental cueing, organization by category and connection to a place may help to prompt memory. New research has revealed that 40% of persons diagnosed with mild cognitive impairment (beyond what is expected for a person of that age and education) are likely to develop Alzheimer's disease within 3 years.
629578936TRUE or FALSE: As adults grow older, reaction time increases.TRUE AND FALSE. Reaction time is the interval that elapses between the onset of a stimulus and the completion of a motor response, such as hitting the brake pedal of a car when the traffic light turns yellow or red. When processing ordinary stimuli, adults do show large INCREASES in response time with increasing age.
629578937TRUE or FALSE: Clinical depression occurs more frequently in older than younger people.FALSE. Depression does NOT occur more often in older adults than younger groups. However, it is the most frequent mental health problem of older adults. Depression may vary from feeling "blue" from grief over a loss to a diagnosis of clinical depression by the DSM IV criteria. Accurate diagnosis and treatment options are often hindered by the resistance to mental health intervention and situational depression in older adults as they react to isolation, role change, illness and medication effects.
629578938TRUE or FALSE: Older adults are at risk for HIV/AIDS.TRUE. Blood transfusions and unprotected sex put older adults at risk for HIV/AIDS as in other populations. It is estimated that as many as 10 percent of all persons diagnosed with HIV/AIDS are over 50 years of age.
629578939TRUE or FALSE: Alcoholism and alcohol abuse are significantly greater problems in the adult population over age 65 than that under age 65.FALSE. There is no substantial support for this idea. A growing body of evidence suggests that, although the majority of older adults are not abstinent, the frequency and quantity of alcohol consumed tends to decrease with age. This is at least partially explained by changing patterns of sociability with age, age related health problems, and complications associated with alcohol interacting with prescribed medications. Problems with drinking later in life appear usually to be a continuation of drinking patterns established in the earlier adult years and not with late onset drinking. Therapeutic intervention is at least as effective with older adults as with adults generally.
629578940TRUE or FALSE: Older adults have more trouble sleeping than younger adults do.TRUE. Older adults are more prone to sleep complaints: insomnia due to changing sleep patterns of frequent awakenings, earlier rising, emotional problems. The quality of sleep declines with age. It becomes particularly more difficult to stay asleep. Daily sedation, boredom, loneliness, illness, time changes, work schedules, physical changes and alcohol or medication may affect sleep patterns. Sleep behaviors common to older adults may include increased napping, periods of sleep apnea (stopped breathing), more frequent awakenings, lengthened onset of sleep, increased time in bed and increased total sleep time. Current research verifies that REM (sleep in which dreaming takes place) deep sleep, in older adults may be half what it is in younger persons.
629578941TRUE or FALSE: Older adults have the highest suicide rate of any age group.TRUE. The national suicide rate is about 12 per 100,000 population, while it is 1.3 for those aged 65 to 74 and 23 per 100,000 for those over age 85. It has been estimated that 17 to 25 percent of all reported suicides occur in persons aged 65 and older. (Hooyman, 178). However, older white males largely account for this high rate. For white women and for men and women of all other races, the suicide rate peaks earlier in the life span. Older adults also have a higher ratio of completed to attempted suicides than younger groups. The higher suicide rates might be explained by a variety of factors, including the loss of roles and status, chronic illnesses that diminish one's sense of control, and social isolation.
629578942TRUE or FALSE: High blood pressure increases with age.TRUE AND FALSE. There is evidence that high blood pressure does INCREASE with age. However, there is controversy over the criteria for high blood pressure. Studies and physicians differ in their definition of high blood pressure. Most consider a person's age plus 100 as a reasonable systolic reading with diastolic of 90 mm. The systolic (higher number) measure is the pressure when the heart is stressed as it contracts and is recorded when the pressure cuff is first released after being tightened. The diastolic (lower number) is the blood pressure when the heart is at rest and is derived when the blood pressure returns to normal after the first rush of blood upon release of the cuff. The Fifth Report of the Joint National Commission on Detection, Evaluation and Treatment of High Blood Pressure states young and old have the same blood pressure, so 140/90 is a standard benchmark. It is thought that more than 50% of persons over 65 years in industrialized society have greater than 140/90.
629578943TRUE or FALSE: Older people perspire less, so they are more likely to suffer from hyperthermia.TRUE. Perspiration and quenching of thirst help to combat overheating. Older adults perspire less, are less aware of thirst and less able to feel or adapt to extremes in temperature than younger persons. Less sensitive skin sensors and less insulation of fatty deposits under the skin and the less efficient functioning of the hypothalamus (the temperature regulating mechanism in the brain) occur in older adults. Prolonged time for older adults to return to core temperature after exposure to extreme heat or cold begins at age 70 years and increases thereafter. Education and taking precautions may prevent most deaths related to temperature extremes. Increased fluid intake, gradual accommodation to climate change, rest, minimizing exertion during heat, use of fans and/or air conditioning, wearing hats and loose clothing and avoidance of alcohol are some strategies for hyperthermia.
629578944TRUE or FALSE: All women develop osteoporosis as they age.FALSE. There is a gradual loss of bony tissue, which causes brittle bones that fracture more easily in both men and women as they age. Osteoporosis develops more often in women when calcium is lost (following hormonal change after menopause) or insufficiently taken and absorbed. Deficiency in bone mineral density occurs in 50% of women over 50 years to 57% of women 70 years or older, but decreases to 45% for those over 80 years. Women rarely develop osteoporosis until age 70 years. A test of bone density (absorptiometry) can measure bone mass by x-ray or computer analyzed e-ray. Prevention of osteoporosis begins with adequate Calcium intake in one's teens and thereafter with increased attention after menopause. Weight bearing exercise, hormone replacement therapy (HRT), decreased alcohol, protein, salt and caffeine consumption, smoking cessation and adequate Vitamin D intake may minimize bone loss. HRT may offer some protection against heart disease, cognitive impairment and bone loss, but also may present risks for cervical cancer. Risk factors of osteoporosis include excess alcohol, little physical activity, deficient calcium intake, no pregnancies, no breast feeding, fair complexion, blond or red hair and of European nationality.
629578945TRUE or FALSE: A person's height tends to decline in old age.TRUE. Due to osteoporosis, osteoarthritis and a lifetime of wear and tear, upper vertebrae are weakened; joint spaces and buffering tissues wear and muscles are lost. These changes foster decreased padding between vertebral discs, which accounts for a loss of height. The height changes and imbalances contribute to pain and stress on the lower back with advanced age.
629578946TRUE or FALSE: Physical strength declines in old age.TRUE. Muscle mass declines, cartilage erodes, membranes fibrose (harden), and fluid thickens. These contribute to stiffness, gait problems, lessened mobility, and limited range of motion. From age 30 years, muscle mass declines to almost 50% in old age. Research shows that weight bearing exercise, aerobics and weight resistance can restore muscle strength, increase stamina, stabilize balance and minimize falls.
629578947TRUE or FALSE: Most old people lose interest in and capacity for sexual relations.FALSE. Recent studies validate that more than 70% of men and women continue sexual activity after 65 years. Men and women over 70 are still considered potentially "sexy," Reasons for limited sexual activity include loss of partners, illness and medications. Most older adults consider intimacy crucial to relationships and emotional well being. Intimacy may be satisfied by other means than sexual relations, such as touch, hugging and holding.
629578948TRUE or FALSE: Bladder capacity decreases with age, which leads to frequent urination.TRUE. The muscle of the bladder loses elasticity and tone. Hence, the bladder holds almost 50% less urine (causing more frequent urination) and empties less completely. The warning period between the urge and actual urination is shortened or lost as one ages. Muscular disability, spinal cord effects on the bladder muscle, tumors, infection, anatomic damage to the sphincters and/or bladder neck may cause incontinence in advancing age. Other risks for incontinence in old age include chronic disease, cognitive impairment, medications, smoking, pelvic muscle weakness, low fluid intake and environment.
629578949TRUE or FALSE: Kidney function is not affected by age.FALSE. The amount of blood flow through the kidney and ability of the kidney to filter blood is about HALF THAT of younger ages. This is caused by the age related structural and anatomic CHANGES within the kidney. Some studies show that as much as ONE THIRD of older adults have no change in their urine creatinine (creatinine clearance is a measure of how well the kidney is able to filter the blood, the glomerular filtration rate or GFR). However other studies show DECLINE that begins at 40 years. Age related kidney changes create more risks for fluid and electrolyte imbalance and renal damage from medications or diagnostic contrast materials. Disease, surgery or fever may stress and interfere with the kidney's ability to regulate and excrete fluids and electrolytes particularly in older adults.
629578950TRUE or FALSE: Constipation increases in more people as they get older.FALSE. Cultural notions about "daily regularity" held by the current cohort of older adults makes the myths of constipation and the elderly seem more important and credible. However, age related changes in the gastrointestinal system are less responsible for constipation in older adults than FACTORS such as activity, diet, and medication. Decreased intake and absorption of vitamins, proteins and other important nutrients and dental issues present greater health threats to older adults. Despite a decrease in gastrointestinal muscle strength and motility, lax sphincters, lowered digestive juices, the gastrointestinal system is better able to compensate for the harmful effects of these changes.
629578951TRUE or FALSE: All five senses tend to decline with age.TRUE. While there is considerable individual variation, on average sensory processes (vision, hearing, taste, smell, and touch) don't work as well as people get older. Another way to say it is that the THRESHOLD at which we TAKE IN stimuli increases with age. The eye lens, for example, is less able to change shape so as to adjust to close and far objects, and the size of the pupil narrows so as to let in less light. Hearing loss begins at age 20, and for many involves growing inability to hear higher frequencies as sensory receptors in the ear and nerve cells in the auditory pathway to the brain are lost. Taste buds become less sensitive with aging, and after age 80 more than 75 percent of older adults show major impairment in their sense of smell. Many of these normal changes can be compensated for through increasingly sophisticated assistive devices (hearing aides, glasses, etc.) and through modifications of the older person's environment.
629578952TRUE or FALSE: As people live longer, they face fewer acute conditions and more chronic health conditions.TRUE. The incidence of acute or temporary conditions, such as infections or the common cold, decreases with age, although those that do occur can be more debilitating and require more care. Older people are much more likely than the young to suffer from chronic conditions. These are long-term (more than three months), often permanent, and leave a residual disability that may require longterm management or care rather than cure. More than 80 percent of persons age 65 and over have at least one chronic condition, with multiple health problems being common. Arthritis is the most commonly occurring chronic condition.
629578953TRUE or FALSE: Retirement is often detrimental to health--i.e., people frequently seem to become ill or die soon after retirement.FALSE. Health decline is related to age or previous health problems, not retirement per se. Retirement may actually improve functional health by reducing stress on the individual.
629578954TRUE or FALSE: Older adults are less anxious about death than are younger and middle-aged adults.TRUE. Although death in industrialized society has come to be associated primarily with old age, studies generally indicate that death anxiety in adults decreases as age increases. Among the factors that may contribute to LOWER ANXIETY are a sense that goals have been fulfilled, living longer than expected, coming to terms with finitude and dealing with the deaths of friends. The general finding that older adults are less fearful of death than middle-aged counterparts should not obscure the fact that some subgroups may have considerable preoccupation and concern about death and dying. Some FEAR THE PROCESS of dying much more than death itself.
629578955TRUE or FALSE: People 65 years of age and older make up about 20 percent of the U.S. population.FALSE. People over age 65 currently make up about 13 percent of the population. However, as the "baby boom" generation begins to turn 65 in 2011 the proportion of older adults will grow dramatically. It is estimated that by 2030 adults over 65 will compose 20 percent of the population.
629578956TRUE or FALSE: Most older people are living in nursing homes.FALSE. According to the U.S. Bureau of the Census, slightly over 5 percent of the 65 population occupy nursing homes, congregate care, assisted living, and board-and-care homes, and about 4.2 percent are in nursing homes at any given time. The rate of nursing home use increases with age from 1.4 percent for the young-old to 24.5 percent of the oldest-old. Almost 50 percent of those 95 and older live in nursing homes.
629578957TRUE or FALSE: The modern family no longer takes care of its elderly.FALSE. Evidence from several studies and national surveys indicates that families are the major care providers for impaired older adults. Families provide 70 to 80 percent of the in-home care for older relatives with chronic impairments. Family members have cared for the typical older adult who reaches a long-term care setting for a significant amount of time first. Research has shown that adult children are the primary caregivers for older widowed women and older unmarried men, and they are the secondary caregivers in situations where the spouse of an older person is still alive. Parent care has become a predictable and nearly universal experience across the life course, although most people are not adequately prepared for it.
629578958TRUE or FALSE: The life expectancy of men at age 65 is about the same as that of women.FALSE. Remaining life expectancy at age 65 is about 4-1/2 years LESS FOR MEN than women. Women have an average remaining life expectancy of 19.4 years compared to 15.0 years for men. Overall life expectancy at birth is about 7 YEARS GREATER for women (80.4) than men (73.5).
629578959TRUE or FALSE: Remaining life expectancy of blacks at age 85 is about the same as whites.TRUE. Although remaining life expectancy of black men and women at age 65 is about two years less than that of white men and women at age 65, by the time they reach 85 their life expectancy is nearly the same. One possible explanation for this convergence effect is that blacks who make it to the oldest ages do so in spite of many disadvantages and are "survivors" and have developed physiological and social psychological survival advantages.
629578960TRUE or FALSE: Social Security benefits automatically increase with inflation.TRUE. Beginning in 1975 Social Security benefits are periodically automatically adjusted to inflation. Current law ties this increase to the consumer price index (CPI) or the rise in the general wage level, whichever is lower.
629578961TRUE or FALSE: Living below or near the poverty level is no longer a significant problem for most older Americans.FALSE. While the proportion of older people (65+) living below the poverty level has declined significantly since 1960 to about 10.5 percent, this index rather dramatically underestimates need. The poverty level is based on an estimate of the cost of items in the Department of Agriculture's least costly nutritionally adequate food plan and multiplied by three (suggesting that food costs represent one third of a budget). This is probably not a fair representation of living costs in many areas of the country, particularly urban areas. Therefore, gerontologists and economists also look at the proportion near poverty level (up to 150 percent of poverty level) and find that nearly one quarter of older adults fall below this line. These older people tend to be disproportionately women,unmarried (including widowed, African American or Hispanic, and living alone.
629578962TRUE or FALSE: Most older drivers are quite capable of safely operating a motor vehicle.TRUE. Some older adults do have visual, motor, or cognitive impairments that make them dangerous drivers. Many drive more slowly and cautiously or avoid driving in conditions they consider threatening in order to compensate for these changes. Until approximately age 85 older adults have fewer driver fatalities per million drivers than men 20 years old, but they do have more accidents per miles driven. Unsafe speed and alcohol use are leading factors in accidents for young drivers, while right-of-way violations are the leading cause of accidents involving older drivers--which implies a breakdown in such cognitive-perceptual components as estimating the speed of oncoming cars or reacting too slowly to unexpected events. Older drivers' skills can be improved considerably by specific driver training such as through the AARP "55 ALIVE/Mature Driving" program.
629578963TRUE or FALSE: Older workers cannot work as effectively as younger workers.FALSE. Negative perceptions of older workers persist because of health issues, diminished energy, discomfort with technology, closeness to retirement, and reaction to change in the work place -- all associated with older adults. To the contrary, research identified characteristics of low turnover, less voluntary absenteeism and fewer injuries in older workers. Recent high ratings of older workers from employers cite loyalty, dependability, emotional stability, congeniality with co-workers, and consistent and accurate work outcomes. While more are retiring earlier and spending fewer years working, older workers will be in greater demand with dwindling entrants into the work force.
629578964TRUE or FALSE: Most old people are set in their ways and unable to change.FALSE. The majority of older people are NOT "set in their ways and unable to change." There is some evidence that older people tend to become more stable in their attitudes, but it is clear that most older people do change. To survive, they must adapt to many events of later life such as retirement, children leaving home, widowhood, moving to new homes, and serious illness. Their political and social attitudes also tend to shift with those of the rest of society, although at a somewhat slower rate than for younger people.
629578965TRUE or FALSE: The majority of old people are bored.FALSE. Older persons are involved in many and diverse activities. After retirement many participate as volunteers in churches, schools or other nonprofit organizations and report themselves to be "very busy." As they age most persons are likely to continue the level of activity to which they were accustomed in middle age.
629578966TRUE or FALSE: In general, most old people are pretty much alike.FALSE. Older adults are at least as diverse as any other age group in the population, and on many dimensions they may actually be more diverse. People vary greatly in their health, social role, and coping experiences. As the older population becomes more and more ethnically diverse, differences could be even greater. It is very misleading to talk about older adults as "the elderly," for this term may obscure the great heterogeneity of this age group.
629578967***TRUE or FALSE: Older adults (65+) have higher rates of criminal victimization than adults under 62 do.FALSE. Although the media may leave the impression that older adults are a major target of violent crime, annual data from the national Crime Victimization Surveys consistently indicate that violent crime, personal theft, and household victimization rates for persons aged 65 and older are the lowest of any age group. Data indicate that this holds true for virtually all categories of criminal victimization: rape, robbery, aggravated assault, simple assault, and personal larceny without contact. Only for the category of personal larceny with contact (e.g., purse snatching and pocket picking) is the victimization rate higher for persons aged 65 and over compared to those aged 25 to 64. Nevertheless, the health and financial consequences may be greater for the older victim.
629578968TRUE or FALSE: Older people tend to become more religious as they grow older.FALSE. Studies have found no increase in average religious interest, satisfaction or activities among older people as they age. The present generation of older persons (cohort) tends to be more religious than younger generations due to their upbringing, i.e., they have been more religious all their lives rather than becoming more religious as they aged. However, research has indicated that religion does seem to become more important with age and older adults do rely on their faith to cope with losses.
629578969TRUE or FALSE: Older adults (65+) are more fearful of crime than are persons under 65.FALSE. Although several surveys show that fear of crime exists among some older adults, there is no substantial evidence that older people are more likely to be afraid of crime than younger people are. One survey examined different types of victimization and found no increase in fear among older adults in any of the types. Studies that have shown an increase in fear of crime in later life possibly have used measures of questionable validity.
629578970TRUE or FALSE: Older people do not adapt as well as younger age groups when they relocate to a new environment.FALSE. While some older people may experience a period of prolonged adjustment, there is no evidence that there is special harmfulness in elderly relocation. Studies of community residents and of institutional movers have found an approximately normal distribution of outcomes -- some positive, some negative, mostly neutral or mixed and small in degree. For many relocation brings a better fit between personal needs and the demands of the physical and social environment. Research generally has demonstrated that adjustment to residential relocation is determined, at least in part, by perceived predictability and controllability and by the similarity between the originating and receiving environments.
629578971TRUE or FALSE: Participation in voluntary organizations (churches and clubs) tends to decline among older adults.FALSE. Women in their 30s and 40s comprise the greatest number of volunteers. However, forty percent of older adults volunteer. Older adults may be less likely to belong to organizations than younger persons, but more consistent in their activities and loyal to groups from middle age until their 60s. Volunteerism is correlated with life satisfaction, usefulness, physical and mental well being and a sense of accomplishment. Persons with higher education and income levels, histories of volunteerism and broad interests are more likely to volunteer. Health problems, lack of transportation and limited income may limit volunteer activities.
629578972TRUE or FALSE: Older people are much happier if they are allowed to disengage from society.FALSE. This view is based upon an early theory called "disengagement theory" which said that it is normal and expectable that the older person and society withdraw from each other so as to minimize the disruption caused by the older person's death. Although many people obviously do scale back certain activities, particularly if health deteriorates, there is substantial evidence that many who remain active and engaged have higher levels of function and happiness. For many staying involved physically, cognitively, socially, and spiritually in the social group is a basis for happiness.
629578973TRUE or FALSE: Geriatrics is a specialty in American medicine.TRUE. Geriatrics refers to the clinical aspects of aging and the comprehensive health care of older persons. Study of geriatrics actually began in the early 1900s, although formal training in geriatrics is relatively new. A Certificate of Added Qualifications (CAQ) in Geriatric Medicine or Geriatric Psychiatry is offered through the certifying boards in family practice, internal medicine, osteopathic medicine, and psychiatry for physicians who have completed a fellowship program in geriatrics.
629578974TRUE or FALSE: All medical schools now require students to take courses in geriatrics and gerontology.FALSE. Although a number of medical schools require course work in geriatrics/ gerontology, many still have only elective courses or no courses at all. Incentives in the form of materials support and grants have come to some medical schools to develop and institutionalize formal curricula from such organizations as the Association of American Medical Colleges, the American Geriatrics Society, and the Association for Gerontology in Higher Education, as well as foundations such as the John Hartford Foundation. Top- ranked medical schools for geriatrics training include Harvard, Duke, Johns Hopkins, Mount Sinai (NY, UCLA, University of Washington, Michigan, Wake Forest, Pennsylvania, and Yale.
629578975TRUE or FALSE: Abuse of older adults is not a significant problem in the U.S.FALSE. The low numbers of reported cases of elder abuse belie the magnitude of elder abuse in this country. Latest figures estimate more than 551,000 reported cases of abuse (physical, verbal and sexual types of neglect or abuse) to persons over 60 years per year. (There are more than 30 million Americans over 60 years.) Actual reported cases represent a fraction of what is thought to occur due to perceived fearful consequences and inconsistent and inefficient report mechanisms. Self neglect and exploitative types of abuse, were not part of the above study and yet are morecommon. Men and women are equally culpable in the perpetration of abuse.
629578976TRUE or FALSE: Grandparents today take less responsibility for rearing grandchildren than ever before.FALSE. The longevity revolution has increased the number of three-, four-, and five-generation families. This, along with a growing incidence of divorce and remarriage, drug and alcohol addiction, AIDS, incarceration, and unemployment within the parental generation has resulted in grandparents stepping into the surrogate parent role with increasing frequency. Census figures estimate the number of grandchildren living with their grandparents (about one third without a parent present) to be as high as 5.5 million, with African American grandchildren being slightly more than three times more likely than their white counterparts to be in this type of living arrangement. There are grandparent- headed households in every socioeconomic and ethnic group.
629578977TRUE or FALSE: Older persons take longer to recover from physical and psychological stress.TRUE. Older adults do experience multiple losses of loved ones and friends, illness, relocation, retirement, income, change and decline in abilities. It may take an older adult longer to adjust to a major change or recover from prolonged and intense physical and emotional stress. The recovery of an older body from a traumatic event may be delayed due to age related decreases in cardiac output and heart rate ad more vulnerability to disease with a less effective immune system. However, the many older adults who have developed active and healthy lifestyles may be able to resist/mitigate some of the negative effects of stress or illness due to their physiological fitness. Likewise, coping skills that have been honed during a lifetime may lessen the damage of psychological stresses and ease adjustments to loss and change.
629578978TRUE or FALSE: Most older adults consider their health to be good.TRUE. The majority of older adults perceive their health to be good to excellent, as they do not compare their current condition to former states, but rather to their peers their ages and older who may be "worse off." The "ratings" are not a medical assessment. While chronic disease, frailty and disability are correlated with advanced age, the Myths and Realities 2000 study discovered that 84% of all Americans would like to live to 90 years and half of persons over 65 years described their lives as "the best years of my life." Disease and disability are being delayed and functional levels are improving, especially in persons over 80 years. Less than 10% of non-institutionalized persons 70 years and over are unable to perform one or more activities of daily living (ADLs). Disability does increase to 22% for those 85 years and older.
629578979TRUE or FALSE: Older females exhibit better health care practices than older males.TRUE. In general women throughout adulthood are more likely to attend to minor symptoms than are men. Men are more likely to have been socialized even as children to be stoical, and consequently are less likely to see a doctor for nonferrous health problems. When they do get sick, they are likely to have more and longer hospital visits. Women, on the other hand, are more likely to have had regular contact with the health care system through childbirth, attending to their children's health, and having regular screening procedures for cervical and breast cancer. Although women report more chronic conditions than men in later life, the severity of their problems tends to be less than that of same age men, probably due to their earlier health care practices -- hence the phrase "women get sicker, but men die quicker."
629578980TRUE or FALSE: Research has shown that old age truly begins at 65.FALSE. Old age is a social construct. Meanings, definitions, and experiences of aging vary across cultures and throughout history. What people consider to be "old" has changed significantly just within the past 100 years in the U.S. as people live longer and healthier. Being identified as "old" is related not only to chronological age, but also health, functional ability, social roles, and self perception. Age 65 is an arbitrary marker that has been associated with eligibility for governmental programs such as Social Security and Medicare (although the age of eligibility for Social Security is gradually being raised to 67 by 2027).
