Shea Hebert · Answer 1

C. The species became more resistant to the insecticide.

Explanation:

The more of something you receive, the more immune you are to it. For example, every year, many people get a flu shot. Flu shots contain small amounts of the flu, and it is inserted into your blood stream so that you may become more immune to the disease when it comes around. The same happens for many living things, including insects.

C. The species became more resistant to the insecticide.

Explanation:

The insects that were resistant to the pesticide survived and reproduced. They passed on the resistance to their offspring. So, the species became more resistant to the insecticide over time. Though some insects died, the species as a whole was able to survive. (got it right on study island)
