Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Asexual reproduction produces plants that are genetically identical to the parent plant because no mixing of male and female gametes takes place.
Explanation:
Self-pollination is when pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms). There are two types of self-pollination: in autogamy, pollen is transferred to the stigma of the same flower; in geitonogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant, or from microsporangium to ovule within a single (monoecious) gymnosperm. Some plants have mechanisms that ensure autogamy, such as flowers that do not open (cleistogamy), or stamens that move to come into contact with the stigma. The term selfing that is often used as a synonym, is not limited to self-pollination, but also applies to other types of self-fertilization.

In this situation, you should direct your partner to manually stabilize the women's head, while you quickly visualize her chest to search for signs of breathing. I hope that this helps you!
The answer is (A) stabilizing selection. Stabilizing selection favors the average in a population. In this case, babies that are born at a normal body weight, or an average between the two extremes of underweight and large, tend to have more favorable outcomes.
