Hope this answered your question.
Answer: (A) Genetic drift
Explanation:
The genetic drift is one of the process of random sampling in which the existent gene frequency are get changed in the organisms and it is also refers as the allelic effect.
According to the given question, In a small remote area the different types of people are living and in that area the "Blue skin" condition is highly incidence due to the variation in the hemoglobin structure.
So, the high frequency in the Blue skin in that specific area is one of the example of the genetic drift and the main role of the genetic drift is to determining the sampling error from the different generation gene.
Therefore, Option (A) is correct answer.
The condensation of water vapor formed the early oceans. It is an important part of the water cycle. It is easy to eliminate the other answers in this question. It can't be meteorites, living organisms, or nitrogen.
From what we know, we can confirm that coral reefs are important ecosystems because they allow for a great diversity of life.
<h3>Why is Biodiversity important?</h3>
Biodiversity is important in an ecosystem. This allows for the ecosystem to become very stable. Diverse lifeforms help the ecosystem maintain population control as well as offer even more food sources for more life forms.
Therefore, we can confirm that coral reefs are important ecosystems because they contain a great diversity of life.
