An energy-transferring compound in cells is a nucleotide known as
8090 [49]

Adenosine triphosphate (ATP) is a complex molecule which provides energy to the cells. This molecule is present in all the living organisms. The chemical energy which is obtained by the body by the breakdown of the food is captured by the ATP (Adenosine Triphosphate) molecules. This captured chemical energy is then transferred by it in order to fuel different body processes.

Hence, the answer is ATP (Adenosine Triphosphate).

Which is the most likely outcome for a species of fish that lacks the genetic variation necessary to adapt to a changing ocean e
ZanzabumX [31]
Genetic variation is the variation in the DNA sequence in the genome of an organisms. Organisms of a species have similar characteristics but they are not identical due to genetic variation. Genetic variation is important in the survival and the adaptability of a given species of organism. Therefore, in this case lack of genetic variation necessary to adapt to change in the environment will lead to extinction of the fish species that lacks the variation.

Which type of mutation is responsible for small changes in a trait
Naddika [18.5K]

<u>Substituion mutation</u>  is responsible for small changes in a trait.

Explanation:

This kind of mutation merely changes the type of nucleotide in the DNA  sequence. The mutation does not cause a frameshift as would a deletion of addition mutation.

A substitution mutation would at worst change an amino acid in the translated protein. This would likely have a slight effect on how the protein folds into an active protein. On the other hand, mutations that cause frameshifts have the biggest effect on the proteins. They change all the amino acids of a protein downstream of the point of mutation.
