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 later in life in certain environments
The positive effects outweigh the negative effects in certain environments
The positive effects appear after reproductive age in certain environments
The negative effects appear before reproductive age in certain environments
The positive effects of an enlarged right ventricle, such as increased oxygen intake, may provide a survival advantage in certain environments where there is high altitude or limited oxygen availability. Individuals with this adaptation may be more likely to survive and reproduce in these environments, passing on this trait to their offspring.
However, the negative effects of an enlarged right ventricle, such as increased risk of pulmonary hypertension, may not manifest until later in life or may not impact reproductive success. Therefore, natural selection may still favor this adaptation despite the negative consequences that may arise in certain individuals.
Overall, the benefits of increased oxygen intake may outweigh the risks of pulmonary hypertension in certain environments, leading to the maintenance of this trait through natural selection.
