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 positive effects appear after reproductive age in certain environments.
The negative effects appear later in life in certain environments.
The negative effects appear before reproductive age in certain environments.
The positive effects outweigh the negative effects in certain environments
In this scenario, natural selection may favor individuals with an enlarged right ventricle that increases oxygen intake, as it may provide a competitive advantage in certain environments, such as high altitudes or during periods of increased physical activity. This adaptation would allow individuals to thrive and reproduce more successfully in these challenging conditions.
However, the same adaptation that increases oxygen intake may also predispose individuals to developing pulmonary hypertension, a condition that can be detrimental to health and longevity. This negative effect may become more apparent later in life, after individuals have already reproduced and passed on their genetic material.
Therefore, natural selection may result in an adaptation that produces both positive and negative effects by favoring traits that provide immediate benefits for survival and reproduction, even if they come with potential risks or drawbacks later on. Ultimately, the overall balance of positive and negative effects will depend on the specific environmental conditions in which the individuals with this adaptation find themselves.
