Bio 182 Exam 2 ASU Questions with
Correct Answers
niche - ANSWERSrange of environmental conditions in which a genotype can persist
abiotic - ANSWERSphysical conditions
biotic - ANSWERSother organisms
which are the strongest bonds - ANSWERScovalent bonds
low temps - ANSWERSmore flexible enzymes
high temps - ANSWERSmore rigid enzymes
Do enzymes maintain a rigid structure while catalyzing? - ANSWERSNo it is constantly
changing
adaptive plasticity - ANSWERSone genotype has multiple phenotypes & environments
trigger change
genetic drift - ANSWERSevolution caused by random processes in population in a
population of finite size
Do smaller or larger populations have more chance for genetic drift? -
ANSWERSSmaller populations
homology - ANSWERSphenotype that is similar between two species because of
common ancestry
homoplasy - ANSWERSphenotype that is similar between two species because of
convergent evolution
parsimony - ANSWERSthe simplest explanation is the best (fewest evolutionary
transitions) A-->B-->C = common A-->B-->A = uncommon
migration load - ANSWERSmaintenance of deleterious alleles by migration
Which traits are more informative? - ANSWERSShared derived traits (synapomorphy)
Which traits provide no information? - ANSWERSShared ancestral traits
(pleisiomorphy)
