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 best response is: The positive effects appear after reproductive age in certain environments.

This answer suggests that the adaptation (increased oxygen intake from an enlarged right ventricle) may provide benefits that help individuals survive and reproduce, while the negative effects (risk of pulmonary hypertension) may manifest later in life, thus not influencing reproductive success. Natural selection favors traits that enhance reproductive fitness, even if those traits carry potential downsides that appear later in life.
