An enlarged right ventricle both increases oxygen intake and the risk of pulmonary hypertension. How can natural selection result in an adaption that produces both positive and negative effects? (1 point)

Question

• The positive effects appear after reproductive age in certain environments.
• The positive effects outweigh the negative effects in certain environments.
O The negative effects appear before reproductive age in certain environments.
• The negative effects appear later in life in certain environments.

Answer 1

The correct answer is:

• The negative effects appear later in life in certain environments.

Natural selection can favor traits that have both positive and negative effects if the negative consequences manifest after reproductive age. This allows individuals with the trait to reproduce successfully before the detrimental effects impact their survival or reproductive success, thereby allowing those traits to persist in the population.
