Question

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

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

Natural selection can result in an adaptation that produces both positive and negative effects if the positive effects of the adaptation are more beneficial for survival and reproduction in a specific environment, despite the negative effects that may arise later on. For example, an enlarged right ventricle may increase oxygen intake, which could be advantageous in certain environments, such as high altitudes or extreme cold temperatures. However, this adaptation may also increase the risk of pulmonary hypertension, which could be detrimental to an individual's health later in life. In this case, if the benefits of the increased oxygen intake outweigh the negative effects of pulmonary hypertension in that particular environment, natural selection could favor this adaptation.
