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 negative effects appear before 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 appear after reproductive age in certain environments. The positive effects appear after reproductive age in certain environments. The positive effects outweigh the negative effects in certain environments.
In this scenario, natural selection could result in an adaptation that produces both positive and negative effects by favoring individuals with an enlarged right ventricle in environments where the positive effects outweigh the negative effects. For example, individuals with enlarged right ventricles may have increased oxygen intake, which could provide a survival advantage in certain environments. However, this adaptation may also increase the risk of pulmonary hypertension, which could have negative effects later in life. Natural selection may favor individuals with this adaptation if the positive effects, such as increased oxygen intake, provide a greater advantage in terms of survival and reproduction compared to the negative effects. Ultimately, the balance between positive and negative effects would determine the overall fitness of individuals with this adaptation in specific environments.
