Bacteria capsule.
Explanation:
The bacteria capsule is a layer of polysaccharides that is around the bacteria membrane. Its principal function is to protect the bacteria from dehydration, destructive toxins, and cells that can destruct the bacteria, such as phagosomes. As a result, the bacteria have a higher probability of surviving and colonizing.
Answer: Timing of the cricket's chirps.
Explanation:
The answer is C. The dark moths were best fit for their environment, since the trees in England were darker due to pollution. The dark moths could best blend into the trees, so birds couldn’t spot them. The white moth population decreased dramatically because they could not blend in with the trees, so they were spotted easier and were thus more vulnerable to predation. This illustrates Darwin’s concept of survival of the fittest. The organisms best fit for the environment live because they have traits and adaptations that enable them to survive. The organisms that do not have these traits, however, will not survive. Since the fit organisms live, they can reproduce and pass on their fitness to their offspring. That’s what makes a species stronger and less vulnerable in their environment. This leads to evolution.
