1623664942Empiricismthe view that knowledge originates in experience and that science should, therefore, rely on observation and experimentation.0
1623664943Structuralisman early school of psychology that used introspection to explore the elemental structure of the human mind.1
1623664944Functionalisma school of psychology that focused on how our mental and behavioral processes function--how they enable us to adapt, survive, and flourish.2
1623664945Experimental Psychologythe study of behavior and thinking using the experimental method.3
1623664946Behaviorismthe view that psychology (1) should be an objective science that (2) studies behavior without reference to mental processes. Most research psychologists today agree with (1) but not with (2).4

1623664948Cognitive Neurosciencethe interdisciplinary study of the brain activity linked with cognition (including perception, thinking, memory, and language).6
1623664949Psychologythe science of behavior and mental processes.7
1623664950Nature-Nurture Issuethe longstanding controversy over the relative contributions that genes and experience make to the development of psychological traits and behaviors. Today's science sees traits and behaviors arising from the interaction of nature and nurture.8

1623664953Biopsychosocial Approachan integrated approach that incorporates biological, psychological, and social-cultural levels of analysis.11
1623664954Behavioral Psychologythe scientific study of observable behavior, and its explanation by principles of learning.12
1623664955Biological Psychologya branch of psychology that studies the links between biological (including neuroscience and behavior genetics) and psychological processes.13
1623664956Cognitive Psychologythe scientific study of all the mental activities associated with thinking, knowing, remembering, and communicating.14
1623664957Evolutionary Psychologythe study of the roots of behavior and mental processes using the principles of natural selection.15
1623664958Psychodynamic Psychologya branch of psychology that studies how unconscious drives and conflicts influence behavior, and uses that information to treat people with psychological disorders.16

1558207799through a microscope you can see a cell plate beginning to develop across the middle of a cell and nuclei forming on either side of the cell plate. The cell is most likelya plant cell in the process of cytokinesis0
1558207800Vinblastine is a standard chemotherapeutic drug used to treat cancer. Because it interferes with the assembly of micrtubles, its effectiveness must be related todescription of mitotic spindle formation1
1558207801one difference between cancer cells and normal cells is thatcancer cells continue to divide even when the are affected by densty-dependent inhibition2
1558207802the decline of MPF activity at the end of mitosis is due tothe degradation if cyclin3
1558207803In the cells of some organisms, mitosis occurs without cytokinesis. This will result incells with more than one nucleus4
1558207804a paticular cell has half as much DNA as some other cells in a mitotically active tissue. This cell is most liekly inG15
1558207805The drug cytohalasin B blocks the function of actin. What aspects of an animal cell cycle would be most disrupted by cytochalasin B?cleavage furrow and cytokinesis6
1558207806A human cell containing 22 automsomes and Y chromosome is asperm7
1558207807which life cycle stage is found in plants but not in animalsunicellular diploid8
1558207808Homologous chromosomes move toward opposite poles of a dividing cell duringmeiosis I9
1558207809meiosis II is similar to mitosis in thatsister chromatids separate during anaphase10
1558207810If the DNA content of a diplod cell in the G1 phase of the cell cycle is X, then the DNA content of the same cell at metaphase of meiosis would be2X11
1558207811What is the badic differnce in how the leading and lagging strands of DNA molecules are synthesized?DNA polymerase can join new nucleotides only to the 3' end of the growing strand12
