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.
Student D 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 growth of the crops after each application.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

i believe it would be c: tons.
