How do humans (and other animals) rely on the products of<br> photosynthesis?
baherus [9]

Answer:

Like plants, humans and other animals depend on glucose as an energy source, but they are unable to produce it on their own and must rely ultimately on the glucose produced by plants. Moreover, the oxygen humans and other animals breathe is the oxygen released during photosynthesis.

just olya [345]

Answer:

B. introns; exons

Explanation:

Related genes from different organism usually translate to proteins of indispensable functions. This means that the proteins must be similar in terms of amino acids produced. Therefore the coding region must be highly conserved. These can be found in the introns. Conversely, exons are not a part of the coding sequence and therefore not required for translation. These sequences may be less conserved.
