Answer:
(2) Over time, these animals will become less likely to survive in a changing environment.
Explanation:
(1) These animals will begin to evolve rapidly.
(2) Over time, these animals will become less likely to survive in a changing environment.
(3) These animals are easily able to adapt to the environment.
(4) Over time, these animals will become more likely to be resistant to disease.
A small population of an organism with limited genetic variation will be less likely to survive in a changing environment over a period of time.
This is because the population will experience a bottleneck effects, a form of genetic drift that happens when a population is small.
<em>Reduced genetic variation limits the number of genes that natural selection can act on as the environment keeps changing with time. Hence, the survival of the population is at risk a a result of changes to the environment.</em>
The correct option is option (2).
