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)

Responses

The positive effects appear after reproductive age in certain environments.
The positive effects appear after reproductive age in certain environments.

The negative effects appear before reproductive age in certain environments.
The negative effects appear before reproductive age in certain environments.

The positive effects outweigh the negative effects in certain environments.
The positive effects outweigh the negative effects in certain environments.

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

Answer 1

The correct response is:

The positive effects outweigh the negative effects in certain environments.

Natural selection can favor adaptations that provide a reproductive advantage even if they also carry some negative consequences. If the benefits (such as increased oxygen intake) significantly enhance survival and reproductive success in specific environments, they can outweigh the potential risks (such as pulmonary hypertension) that may manifest later in life or do not affect reproductive success.
