Hello,

I am not too sure on this one, but I think it is E? b/c the plants are abundant and evenly distributed.

In the Sierra Nevada Mountains of California there are many populations of the checkerspot butterfly Euphydryas editha. You notice that females of one population lay their eggs near the tip of a plant’s stem (population A). Females of another population in the same area lay their eggs at the base of the stem on a different type of plant (population B). The young hatch out as caterpillars; they live on the host plant and eat its leaves. The different plants used by the checkerspot butterfly populations are both abundant and evenly dispersed in the habitat. This suggests that host plant distribution would ____________ the distribution of checkerspot butterflies within the habitat.

A. None of the responses are correct.

B. be the only factor in

C. be a limiting factor

D. depend on

E. have no effect on
