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 later in life in certain environments.
The negative effects appear later in life 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 most appropriate response is:

The positive effects outweigh the negative effects in certain environments.

This option suggests that in some environments, the advantages of an enlarged right ventricle (such as increased oxygen intake) can lead to better survival or reproductive success, despite the associated risks (like pulmonary hypertension). Natural selection favors traits that enhance fitness, even if they come with potential downsides later in life or under certain conditions.
