Answer:

A zebra migrates to join a different herd of zebras. Gene flow

Competition for sunlight leads to taller trees. Natural Selection

The DNA of a snake changes to make its venom stronger. Mutation

A grass fire randomly sweeps through a population of buffalo and kills most of the animals. Genetic drift

Explanation:

Gene flow: Gene flow can be described as the transfer of genes or genetic variation from one population to another. Hence, the migration of a zebra to a different herd of zebras is a kind of gene flow.

Natural Selection: The phenomenon of natural selection favors those organisms which have better characteristics to survive in an environment. Hence, natural selection favours the taller plants.

Mutation: Mutation can be described as any change which occurs in the DNA of an organism. Hence, a change in the DNA of the snake is mutation.

Genetic Drift: Genetic drift is the change in the gene frequency of an area due to certain disastrous conditions such as a fire.
