Natural selection can result in adaptations that produce both positive and negative effects if the advantages provided by those adaptations enhance reproductive success in a particular environment before any negative consequences significantly impact survival or reproduction. In this case, the most appropriate response would be:
**The positive effects outweigh the negative effects in certain environments.**
This indicates that in some environments, the benefits of having an enlarged right ventricle (such as increased oxygen intake) may lead to greater reproductive success, even though there are potential later risks (like pulmonary hypertension). Therefore, if the positive effects contribute to survival and reproduction, those traits may persist in the population despite the associated costs.
