Answer:
The correct options
A) Roaches ate about the same amount from the dish with no hydramethylnon as they did from the control dish.
B) Roaches ate about the same amount from the dish with no oleic acid as they did from the control dish.
F) Roaches are refusing corn syrup.
Explanation:
In this situation (before pesticides were ever recommended for cockroaches) a particular subdivision of the population was genetically more inclined to avert oleic acid for some particular purpose. Traits such as this float all through populations and adds to genetic variance. When pesticides are recommended to the population, cockroaches with the formerly neutral trait of oleic acid aversion would have a notable advancement concerning its relative fitness.
