BIO 182 EXAM 2 ASU WITH
DETAILED ANSWERS GRADED
A+ LATEST UPDATE 2026
niche - answer-range of environmental conditions in which a genotype can persist
abiotic - answer-physical conditions
biotic - answer-other organisms
which are the strongest bonds - answer-covalent bonds
low temps - answer-more flexible enzymes
high temps - answer-more rigid enzymes
Do enzymes maintain a rigid structure while catalyzing? - answer-No it is constantly
changing
adaptive plasticity - answer-one genotype has multiple phenotypes & environments
trigger change
genetic drift - answer-evolution caused by random processes in population in a
population of finite size
Do smaller or larger populations have more chance for genetic drift? - answer-Smaller
populations
, homology - answer-phenotype that is similar between two species because of common
ancestry
homoplasy - answer-phenotype that is similar between two species because of
convergent evolution
parsimony - answer-the simplest explanation is the best (fewest evolutionary
transitions) A-->B-->C = common A-->B-->A = uncommon
migration load - answer-maintenance of deleterious alleles by migration
Which traits are more informative? - answer-Shared derived traits (synapomorphy)
Which traits provide no information? - answer-Shared ancestral traits (pleisiomorphy)
Which traits provide false info? - answer-Convergent traits (homoplasy)
allopatry - answer-populations occur in different places
sympatry - answer-populations occur at the same place same time
plasticity - answer-ability of one genotype to produce more than one phenotype when
exposed to different environments
Genetic drift can do what to neutral alleles - answer-eliminate & spread
What random processes cause genetic drift? - answer--independent assortment of
alleles
-random variation in survival
