Which student’s explanation would be most useful in demonstrating how pesticide resistance develops in a population? (DOK 3) A.
Student A proposes a model showing how the quantity of pesticide used compares to population size after breeding season for the pests, and how this correlates with rainfall.

B.
Student B proposes a model showing how quantity of pesticide used compares to population size after breeding season for the pests, and how this correlates with average temperature.

C.
Student C proposes to model the application of pesticides and how before and after each application this affects the ratio of phenotypes in each generation and the pest population size after each application.

D.
