Which of the following best describes how natural selection results in insects that are pesticide resistant?
|
When a pesticide is sprayed on a crop, a few insects survive. These insects happen to have a random mutation that makes them resistant to the pesticide. These insects survive and reproduce, eventually resulting in pesticide-resistant population.
|
|
When a pesticide is sprayed on a crop, the insects respond by mutating their DNA, making them resistant to the pesticide. Therefore, a pesticide resistant population evolves.
|
|
When a pesticide is sprayed on a crop, it causes mutations in the insect DNA. Some of these mutations make the insects pesticide-resistant. These insects now form a pesticide-resistant population.
|
|
When a pesticide is sprayed on a crop, it kills the insects, which allows a new species to migrate into the habitat. Some of these species are pesticide resistant, thus a new population of pesticide resistant insects appears.

Explanation:
Detailed explanation-1: -Pest species evolve pesticide resistance via natural selection: the most resistant specimens survive and pass on their acquired heritable changes traits to their offspring. If a pest has resistance then the pesticide lacks efficacy – efficacy and resistance are inversely related.
Detailed explanation-2: -Answer and Explanation: The evolution of pesticide resistance is best described as B) offspring of insects that are genetically resistant to the pesticide become more abundant as the susceptible insects die off .
