Question

A company develops a new pesticide that kills insects. When the pesticide is first used, it kills nearly all the insects. Which statement explains why after 10 years, nearly all the insects can tolerate the pesticide and survive? A.

Those resistant insects survived and reproduced, passing on traits that helped them survive onto their mutant offspring.
