Answer:
<u>Animals and plants use oxygen for processing cellular respiration.</u>
Explanation:
Most of all organisms use oxygen to undergo cellular respiration with the help of the mitochondria that powers energy. Cellular respiration is needed to obtain energy for survival. As products of cellular respiration, ATP energy is created, and carbon dioxide + water is released from the organism. Thus, an ecosystem like a rainforest with animals and plants use oxygen for processing cellular respiration.
The change in crab color is an example of Disruptive selection because two extreme colors were preferred over the more moderate color. Thus, the correct option for this question is D.

Answer:
Option A is absolutely correct
Explanation:
The genotype of an organism is its complete set of genetic material. However, the term is often used to refer to a single gene or set of genes, such as the genotype for eye color. The genes partly determine the observable characteristics of an organism, such as hair color, height, etc.
In a broad sense, the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.
