Question

how can having a large population keep the population in hardy-weinberg equilibrium?
a large population is easily affected by changes, so the population evolves quickly.
a large population is not easily affected by changes, so the population does not evolve as quickly.
a large population cannot help keep the population in hardy-weinberg equilibrium.

Explanation:

The Hardy - Weinberg equilibrium assumes no evolution. A large population size reduces the impact of genetic drift (random changes in allele frequencies). Genetic drift has a more significant effect in small populations. In a large population, random changes in allele frequencies (due to chance events like which individuals reproduce) are averaged out. So, a large population is less likely to have significant allele frequency changes (a requirement for evolution), thus helping to maintain Hardy - Weinberg equilibrium.

Answer:

A large population is not easily affected by changes, so the population does not evolve as quickly.
