The answer would be B. chromosome 21
Individuals of the same species have different traits because they have different genes which code for different proteins. B would be the correct option.
<h3>Variations</h3>
Organisms of the same species can have different traits due to a difference in their proteins.
Genes are responsible for proteins and proteins are an expression of traits. Thus, with different proteins come different traits.
Hence, once there is a difference in the DNA sequence of organisms, different proteins will be produced, and different traits will be expressed.

Answer;
-Oxygen
Explanation;
Both the glucose and oxygen produced in photosynthesis are used in aerobic respiration.
-Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis.
-While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
