Question

read this passage about two inherited traits in stick insects.
a stick insect may have solid coloring or stripes on its body. each type of coloring can help an insect blend in with a certain type of leaf. this helps the insect avoid predators, such as birds and lizards.
stick insects with solid green coloring blend in well with wide leaves. on stick insects that have green bodies with white stripes, the stripes make the insects bodies look like thin green ribbons. so these insects blend in well with thin, needle-like leaves.
a stick insect with stripes
the stick insects environment changed to have more plants with wide leaves than with thin leaves. after this change, over a time period long enough for natural selection to occur, the percentage of the stick insect population with stripes decreased.
use the theory of natural selection to construct a possible explanation for how the stick insect population adapted to its changed environment.
having solid coloring was advantageous than having stripes after the environment changed. so the alleles for stripes were passed on with frequency than the alleles for solid coloring. as a result, the proportion of the population with stripes . over time, the population adapted such that the percentage of insects that were not well camouflaged .

Explanation:

1. After the environment shifted to have more wide leaves, solid-colored stick insects were better camouflaged, making this trait more advantageous than stripes.
2. Striped insects were more visible to predators, so they survived and reproduced less often, meaning their alleles were passed on less frequently than solid coloring alleles.
3. With fewer striped insects reproducing, the proportion of striped insects in the population decreased.
4. As natural selection favored well-camouflaged (solid-colored) insects, the percentage of poorly camouflaged (striped) insects decreased over time.

Answer:

Having solid coloring was more advantageous than having stripes after the environment changed. So the alleles for stripes were passed on with lower frequency than the alleles for solid coloring. As a result, the proportion of the population with stripes decreased. Over time, the population adapted such that the percentage of insects that were not well camouflaged decreased.
