Semester 2: Biology Vocabulary Dominant - A comparative term, where one allele is expressed over the other True Breeding- The process of breeding of two organisms with an identical phenotype to procreate an organism with the same phenotype Recessive ? A comparative term, where one allele is not expressed over the other Sexual selection ? A process where mate is chosen based on certain characteristics or traits Homologous structures ? Structures that appear to be similar in different organisms, suggesting a common ancestry or an evolutionary origin. Selective breeding ? A process of breeding for a particular genetic trait Derived structures ? Structures that appear in the ancestor of a group or species, but do not appear in the other species.

Reuben Chemmanam K. Medlin English 2 5 September 2013 The Ugly Facts The outline of this author?s article implies that America?s new generation is heading into a discouraging future. Furthermore, she states that only 33 percent of eighth-graders and 24 percent of twelfth-graders were proficient at writing with only a pencil and paper in 2007. The author blames misspelled advertisements, language-poor environments, and schools. Her argument mostly dwells on the lax method of teaching writing in modern education. The article suggests we push every one of our pupils to learn how to write despite their learning styles. Overall she says that teaching the students how to write proficiently makes them successful in life.

August 2013 Chapter 22 Descent with Modification A Darwinian View of Life Darwin introduces a new theory Charles Darwin published On the Origin of Species by Means of Natural Selection on November 24, 1859 It focused on the diversity of organisms Their origins and relationships Their similarities and differences Their geographic distribution Adaptation to surrounding environments Presented evidence that many species from earth are descendants of ancestral species that were different from the modern species Proposed a mechanism for this process, which name is Natural Selection Natural Selection is that a population can change over generations, leaving heritable traits to their breeds, this population can get a lot of changes that can eventually form to a new specie

August 2013 Chapter 23 The Evolution of Populations 23.1 Population genetics provides a foundation for studying evolution Darwin and Mendel were contemporaries of the 19th century At the time both were unappreciated for their work Microevolution ? the generation-to-generation change in the population?s frequencies on alleles The Modern Synthesis The turning point for revolutionary theory was the development of population genetics Population Genetics ? Study on how a population changes over time Emphasizes genetic variation and recognizes the importance of quantitative characters Gene Pools and Allele Frequencies A population?s gene pool is defined by it?s allele frequencies (quantity of alleles in a population) Population ? a group of organism that belong to the same species

Chapter 1 Inquiring About the World of Life: Evolution: fundamental organizing principle of bio Biology: scientific study of life Answer questions about our everyday lives Evolution is core of bio New properties exist at each level of biology Emergent properties: arise at each level that do not exist at the preceding level Systems Biology: goal is to model the dynamic behavior of bio systems Organisms interact with environment Structure and Function Correlate at all levels Cells are basic units of structure and function Eukaryotic cell: subdivided into internal membranes Prokaryotic cell: simpler and smaller than eukaryotic cell Life based on information in form of DNA Genes: units that transmit inheritance info Genome: ?library of genetic instructions an organism inherits?

Cycles of Life: EXPLORING BIOLOGY Module 1: Biological Concepts Segment 1: The Unity and Diversity of Life Objectives: 1. List and describe major characteristics of living things that distinguish them from non-living matter. 2. Describe the general pattern of energy flow through the earth?s life forms, and explain how their interactions help cycle the earth?s resources. 3. Explain what is meant by the term unity, and identify possible causes of similarities between earth?s organisms. 4. Explain what is meant by the term diversity, and identify possible causes for the great diversity of life forms on earth. Video Synopsis: Beginning with the features that distinguish living matter from non-living matter, this segment provides

Exam 4 review sheet Chapter 3 Hydro cycle Solar energy heats Earth, and causes evaporation Evaporated water condenses into clouds Water returns to Earth as precipitation Precipitation falling on land is taken up by plants, runs off along the land surface, or percolates into the soil and enters the groundwater Carbon cycle Carbon is the most important element in living organisms makes up 20 percent of total body weight. Produces convert CO2 into sugars Sugars are converted back into CO2 Some carbon can be buried Human extraction of fossil fuels brings carbon to Earth?s surface, where it can be combusted C02 in the atmosphere and CO2 dissolved in water are constantly exchanged Combustion converts fossil fuels and plant material into CO2 Nitrogen cycle
