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)

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 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.

Answer 1

The appropriate response is:

The negative effects appear later in life in certain environments.

This option indicates that individuals may gain certain benefits (like increased oxygen intake) during their reproductive years, while the negative effects (like the risk of pulmonary hypertension) may become more pronounced later in life, potentially after they have already reproduced. This scenario can allow for the positive effects to be favored by natural selection, even in the presence of negative outcomes.
