Question

which population of organisms would most likely be in hardy-weinberg equilibrium, and thus nonevolving?
○ a population of bacteria that is naturally occurring in a humans digestive tract
○ a population of killer whales living in the atlantic ocean
○ a population of crocodiles living in the nile river
○ a population of mice in a laboratory

Explanation:

Hardy-Weinberg equilibrium requires no mutation, random mating, no gene flow, infinite population size, and no selection. Laboratory mice populations are often controlled: mating can be random, gene flow is prevented, population size is stable, and selection pressures are minimized—conditions closest to equilibrium. Natural populations (bacteria, killer whales, crocodiles) face mutations, non-random mating, gene flow, or selection, violating equilibrium conditions.

Answer:

a population of mice in a laboratory
