Answer:

D) a population's allele frequencies change over a span of generations.

Explanation:

Microevolution occurs within a population whereby gene flow, mutation, genetic drift or natural section brings about a change in a population’s allele frequencies over several generations. It occurs on a small scale. Examples of microevolution can be observed in resistance being evolved by pests to pesticides. i.e. Mosquitoes developing resistance against DDT. Mosquitoes with genes that can withstand DDT have evolved overtime.

According to the principle of _______, a change in one species in a community results in a change in another.
Monica [59]

The correct answer is coevolution.

The term is used to illustrate the conditions where two or more species communally influence each other’s evolution. For example, an evolutionary modification in the morphology of a plant may influence the morphology of a herbivore that consumes it, this, in turn, may influence the evolution of the plant that might influence the evolution of the herbivore and so on.

Coevolution most possibly takes place when distinct species have a close ecological association with each other. These ecological associations include parasite/host and predator/prey, mutualistic species, and competitive species.
