ANTHROPOLOGY EXAM 3 WVU WITH CERTIFIED SOLUTIONS what makes us human? Bipedalism, brains, skulls, Childhood dependency, tools, teeth biopedalism stresses the advantages it provided in a habitat increasingly dominated by dry, savanna-like conditions. Brains and skulls Early hominins had very small brains, Brain size has increased during hominin evolution, especially with the advent of the genus Homo. Childhood dependency Compared with the young of other primates, human children h...

BIO 101 Exam 3 Salihu WVU with Certified Answers chromatin material chromosomes are made of; consists of RNA, DNA, and protein sister chromatids replicated chromosomes that are identical homologues maternal and paternal copies of a chromosome centromere region of contact after replication located near the middle of two strands spindle fibers fibers that extend from one side of the cell to the other that pull the sister chromatids in anaphase of mitosis cytokinesis stage fol...

Anthropology Exam 1 WVU Latest Update Graded A+ the measure of success under natural selection is a. how many offspring are produced b. whether an individual lives or dies c. how well adapted an individual is d. how well adapted the species is a. how many offspring are produced founder effect: a. is a type of genetic drift that results when only a small number of individuals from a larger propulsion starts a new population b. is a for of gene flow in which muted genes are rec...

Bio 115 WVU Final (Dr. Barry) Questions and Answers Graded A+ For e. coli , the lacl repressor gene is expressed when? The lacl repressor gene is always expressed Where does the lacl repressor gene attach The lacl repressor gene codes for a protein which attaches to the lac operon operator In the absence of lactose, does the lacl repressor gene bind to DNA Yes, in the absence of lactose, the lacl repressor gene binds to DNA preventing transcription; this is an example of negative...
