Question

which of the following best describes how pesticide resistance can develop? pests that survive pesticide exposure pass on resistance to their offspring. pesticides become more effective with prolonged use. pesticides kill all pests upon first exposure. pests become more susceptible to pesticides with each generation.

Explanation:

To determine how pesticide resistance develops, we analyze each option:

• Option 1: Pests with genetic traits allowing survival after pesticide exposure reproduce, passing resistance genes to offspring. This aligns with natural selection (evolutionary concept in biology) for pesticide resistance.
• Option 2: Prolonged pesticide use typically reduces effectiveness (pests develop resistance), so this is incorrect.
• Option 3: Pesticides rarely kill all pests initially; some may have resistance traits, so this is false.
• Option 4: Pesticide resistance means pests become LESS susceptible over generations, so this is incorrect.

Answer:

A. Pests that survive pesticide exposure pass on resistance to their offspring.
