How are bacteria able to adapt to a rapidly changing environment?

1 answer:

7 0

They adapt because they can replicate quickly (have many generations within short period of time) and accumulate mutations. Mutations in their genetic information allows them to bypass the host's immune system or resist to antibiotics. These mutations are successfully carried to the next generations of bacteria and allows them to thrive in their new environments.

- Results in descent with modification

- Involves differential reproductive success

- All of the above

Answer:

The correct option is d) All of the above

Explanation:

The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
