Question

genetic variation can aid in the survival of species when the environment changes. which of the following is the best example of an organism with a genetic variation that could improve survival chances over time? a an ant that is resistant to pesticide b a wasp that is infected with parasites c a cactus that has no spines d a mouse that has learned to avoid mousetraps

Explanation:

• Option A: An ant resistant to pesticide has a genetic variation that helps it survive in an environment where pesticides are used. This trait can be passed on to offspring, increasing the chances of the ant population's survival over time.
• Option B: A wasp infected with parasites is at a disadvantage and is less likely to survive and reproduce, so this is not a beneficial genetic variation for survival.
• Option C: A cactus without spines is more vulnerable to being eaten by herbivores, reducing its survival chances. Spines are an important adaptation for cacti in their environment.
• Option D: A mouse learning to avoid mousetraps is a learned behavior, not a genetic variation. Learned behaviors are not passed on genetically in the same way as genetic traits.

Answer:

A. An ant that is resistant to pesticide
