Question

Quizplus · Accepted Answer

Pesticide resistance happens when a population of pests undergoes genetic changes that enable some members to survive exposure to a pesticide. Over time, these resistant individuals reproduce, and their offspring inherit the resistance, making the pesticide less effective. This process is an example of natural selection, where the traits that confer survival advantages become more common in the population.
