Question

which of the five factors that can lead to evolution would operate on a change in body color that enabled animals to better hide from predators? a. natural selection b. genetic drift c. sexual selection d. gene flow

Explanation:

The question is about which evolutionary factor operates on a body - color change that helps animals hide from predators. Natural selection is the process where organisms with traits (like better camouflage via body color) that enhance their survival and reproduction are more likely to pass on their genes. Genetic drift is random change in allele frequencies, sexual selection is about traits for mating success, and gene flow is transfer of genes between populations. So natural selection is the factor here.

Answer:

A. natural selection
