Here are the answers based on the questions you've provided:

Question 10: How does gene flow affect genetic variation?

  • The correct response is: Increases genetic variation within a population.
    Gene flow, which is the transfer of genetic material between populations, tends to increase genetic diversity within a population by introducing new alleles.

Question 11: In a population of rabbits, individuals with thicker fur survive better in a cold climate. What is likely to happen over time?

  • The correct response is: Rabbits with thicker fur will become more common.
    This is an example of natural selection, where individuals with advantageous traits (thicker fur) are more likely to survive and reproduce, leading to those traits becoming more prevalent in the population over time.

Question 12: Why is genetic variation important in populations?

  • The correct response is: It enhances the ability of a population to adapt to changing environmental conditions.
    Genetic variation is crucial for the survival and adaptability of a population, as it provides the raw material for evolution and enables populations to adjust to new challenges in their environment.
