Which statement best describes a forest ecosystem that has not experienced any disturbances or natural disasters in the past 100
sveticcg [70]

Answer:

The given question is incomplete, as there is no options provided, and are not available anywhere. But in general, if a forest ecosystem has not experienced any kind of disturbances or natural disasters in the last 100 years then the various plants and animals species dwelling in that forest are reasonably stable.

Explanation:

A forest ecosystem is usually defined as a distinct ecosystem that is comprised of trees, plants and animals, and micro-organisms, in an area that interacts with the abiotic factors such as water, soil in order to survive.

If a forest ecosystem is not disturbed by any anthropogenic or natural disasters for the past 100 years, then the species living in this ecosystem becomes reasonably very stable. They will be adapting to the environment and habitat becomes permanent. There will not occur much physiological and morphological variation in these species.

How does sexual reproduction compare to DNA transfers in prokaryotes? (2 points)
Andreyy89

Answer:

The correct answer is b. I and II

Explanation:

Sexual reproduction is present in higher forms of life and absent in prokaryotes like bacteria. Sexual reproduction results in greater evolutionary changes due to the fusion of two different gametes from two different individuals of a species.

Therefore sexual reproduction helps in increased genetic diversity in higher forms of life. In prokaryotes like bacteria, genetic diversity is maintained and increased through DNA transfer from one bacterial cell to another with the help of a process known as horizontal gene transfer.

Bacteria have sex pilli which is used to introduce the genes to the other bacteria. By this process, they increase their genetic diversity and evolve continuously. So the correct is b. I and II.
