pesticides are chemicals that are often sprayed on crops to kill plant-eating insects, preventing damage to the crops. WHile pesticides are effective initially, many researchers claim that any single pesticide will see reduced effectiveness in as little as ten to fifteen years. Which of the following best supports the claim by scientists that the pesticides will eventually lose their effectiveness?
A. Insects will evolve to avoid any plant sprayed with pesticides to increase their chances of survival.
B. Insects that are naturally resistant to the pesticide will survive and reproduce more than the insects that are sensitive to the pesticide.
C. The insects will build up a tolerance to the pesticides, and eventually the pesticide will not affect them.
D. The pesticides will increase the mutation rate in the insects, resulting in higher genetic diversity and higher survival rate.

Pesticides will eventually lose their effectiveness as the pesticides will increase the rate of mutation in the insects, resulting in higher genetic diversity and higher survival rates. So, the correct option is D.

What are Pesticides?

Any chemical or substance used for destroying the activity of insects or other organisms harmful to cultivated plants or to animals is known as pesticides.

It has been observed by scientists that the pesticides will eventually lose their effectiveness because pests have developed resistance - a significant decrease in sensitivity to a pesticide. The pesticide that is sprayed on crops allows increasing the mutation rate in the insects leads to increases in genetic diversity as well as their survival rate.

Therefore, Pesticides will eventually lose their effectiveness as the pesticides will increase the rate of mutation in the insects, resulting in higher genetic diversity and higher survival rates.
