Question

a group of students were discussing some examples of various evolutionary mechanisms. which table correctly pairs each example with its evolutionary mechanism? example 1: wildfires in australia kill an estimated 30% of the continents koalas. example 2: a change in the dna for human red blood cells can cause the cells to be sickle - shaped, providing some resistance to malaria. example 3: pollen from flowers on one side of a river is transported by bees to a population of flowers on the opposite side of the river.

Explanation:

• Example 1: Wildfires killing 30% of koalas is a random event changing allele frequencies, which is genetic drift.
• Example 2: A change in DNA of red - blood cells is a mutation as it alters the genetic material.
• Example 3: Pollen being transported across a river to another flower population is gene flow as it involves the transfer of genetic material between populations.

Answer:

A. Example 1: Genetic Drift, Example 2: Mutation, Example 3: Gene Flow
