A research project was conducted to study the effect of permethrin when used as insecticide, but some mosquitoes have become resistant to permethrin. The research included the following steps. A sample of mosquitoes was treated with the insecticide. The majority of the mosquito population died, but a small percentage survived. From the survivors, a line of resistant mosquitoes was bred. The DNA of the non–resistant strain was compared with DNA from the resistant strain. Before analyzing the DNA, the researchers conducted an experiment to make sure they had produced a strain of resistant mosquitoes. This experiment included the following steps.

Question
A research project was conducted to study the effect of permethrin when used as insecticide, but some mosquitoes have become resistant to permethrin. The research included the following steps.
- A sample of mosquitoes was treated with the insecticide.
- The majority of the mosquito population died, but a small percentage survived.
- From the survivors, a line of resistant mosquitoes was bred.
- The DNA of the non–resistant strain was compared with DNA from the resistant strain.
Before analyzing the DNA, the researchers conducted an experiment to make sure they had produced a strain of resistant mosquitoes. This experiment included the following steps.
The responding variable in this experiment was the
- A sample of wild–caught mosquitoes and a sample of the resistant strain of mosquitoes were treated with permethrin.
- The percentage of mosquitoes surviving in each sample was calculated.
The responding variable in this experiment was the
Select one:
a. exposure of mosquitoes to permethrin
b. resistant mosquito sample
c. number of mosquitoes that survived
d. total mosquito sample
