How does gene flow directly contribute to evolution? I'll mark brainliest Question 8 options:
A. It changes the environment in which a population resides.
B. It introduces new alleles into a population.
C. It drastically increases the number of members in a population.
D. It reduces the number of members in a population.

The correct answer is - B. It introduces new alleles into a population.

Explanation:

Gebe flow or migration is the transfer of the genetic material or transfer of genes from one population to another population of the same species. Gene flow is also responsible for the genetic change that leads to evolution.

Gene flow can contribute in various ways such as migration or vertical gene transfer parent to progeny, however, it can lead to evolution directly by introducing new alleles into a population.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
