A population of insects has a brown color, providing them with camouflage on the desert sands where they live. Over thousands of years, climate changes in the area cause grasses to grow, and the population of insects becomes green over the same period of time. Which term describes what has taken place in the population of insects? a. mutation
b. evolution
c. migration
d. variation

B.

Explanation:

Evolution is a change in the gene pool of a population over time. It occurs throughout the whole population. The gene pool in this situation changes from consisting of genes for mostly brown-colored insects to green. Mutation only occurs in individuals. Migration refers to population moving locations. Variation is just the different genes in a gene pool.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

the answer is 95 degrees
