If the mechanism of resistance to permethrin in a species of mosquito is detoxification by an enzyme, and you inhibit that enzyme in that mosquito, which of the following is true? It will take less time to kill 50% of mosquitoes in that group than in a control group that has not had its enzyme inhibited. It will take more time to kill 50% of mosquitoes in that group than in a control group that has not had its enzyme inhibited. The population resistant to permethrin will also be resistant to DDT, so blocking the detoxification enzyme and then exposing a test group to DDT will result in the same time to kill 50% of the test population. It will take less time to kill 50% of mosquitoes in that group than in a control group where the enzymé had not even evolved. The population resistant to permethrin will also be resistant to DDT and the time to kill 50% of the test population when exposed to DDT or permethrin will be the same, regardless of whether the detoxification enzyme is blocked or not.

Question
If the mechanism of resistance to permethrin in a species of mosquito is
detoxification by an enzyme, and you inhibit that enzyme in that mosquito, which of
the following is true?
It will take less time to kill 50% of mosquitoes in that group than in a control
group that has not had its enzyme inhibited.
It will take more time to kill 50% of mosquitoes in that group than in a control
group
that has not had its enzyme inhibited.
The population resistant to permethrin will also be resistant to DDT, so blocking
the detoxification enzyme and then exposing a test group to DDT will result in
the same time to kill 50% of the test population.
It will take less time to kill 50% of mosquitoes in that group than in a control
group where the enzymé had not even evolved.
The population resistant to permethrin will also be resistant to DDT and the
time to kill 50% of the test population when exposed to DDT or permethrin will
be the same, regardless of whether the detoxification enzyme is blocked or not.
