niche - correct answer ✔✔range of environmental conditions in which a genotype can persist
abiotic - correct answer ✔✔physical conditions
biotic - correct answer ✔✔other organisms
which are the strongest bonds - correct answer ✔✔covalent bonds
low temps - correct answer ✔✔more flexible enzymes
high temps - correct answer ✔✔more rigid enzymes
Do enzymes maintain a rigid structure while catalyzing? - correct answer ✔✔No it is constantly changing
adaptive plasticity - correct answer ✔✔one genotype has multiple phenotypes & environments trigger
change

finite size
Do smaller or larger populations have more chance for genetic drift? - correct answer ✔✔Smaller
populations
homology - correct answer ✔✔phenotype that is similar between two species because of common
ancestry
, homoplasy - correct answer ✔✔phenotype that is similar between two species because of convergent
evolution
parsimony - correct answer ✔✔the simplest explanation is the best (fewest evolutionary transitions) A--

-random variation in fecundity
Is fixation of a deleterious allele or the loss of a beneficial allele more probable? - correct answer
✔✔Loss of a beneficial allele
