Anit [1.1K]

Answer:

A source from which organisms generally take elements is called exchange pool (option B).

Explanation:

Options for this question are:

  • <em>Food web.</em>
  • <em>Exchange pool.</em>
  • <em>Reservoir.</em>
  • <em>Biotic community.</em>

The term exchange pool is related to the biogeochemical cycles that exist in nature, referring to the source from which elements present in the environment become part of living organisms.

<u>Exchange pools are the biotic components</u> -like animals and plants- of an ecosystem, which determine the passage of elements between living beings. An element can remain as a reservoir (abiotic) in the soil, and then be incorporated into the exchange pool.

In a certain population of rabbits the allele for brown fur is dominant over the allele for white fur if 10 out of 100 rabbits h
grandymaker [24]

The Hardy-Weinburg equation is p + q = 1, or p^2 + 2pq + q^2 = 1, where p is dominant and q is recessive. If 10 out of 100 rabbits have white fur, 10% of the rabbits have white fur. Therefore, 90% of the rabbits have brown fur, which can be substituted into the first equation to become 0.9 + 0.1 = 1. Now that we know what p and q equal, we can solve the rest of the equation.

0.9^2 = 0.81

0.9 * 0.1 * 2 = 0.18

0.1^2 = 0.01

Therefore, the allele frequency of the recessive allele is 0.1
