Explanation:
The effects described are called phototropism, where light affects the direction of growth of the plant.
Auxin is a plant growth hormone that promotes growth of the plant by encouraging cell proliferation.
Light degrades auxin, so it is found more in the shaded side of the plant. This causes the cells in this region to proliferate more, and therefore there is more growth on the shaded side of the plant.
This causes the plant to bend towards the light.
According to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.
<h3>What is population genetics?</h3>
