Answer:
This is a picture of an aminoacid chain
Explanation:
In an amino acid chain all amino acids ( for example GLY, VAL, or ARG) are linked by peptide bonds. Long chains, also called polymers, of amino acids are called proteins. The enlarged photo is an example of a structure of an amino acid. They have an amine (-NH2) and carboxyl (-COOH) functional group, along with a side chain (R group), specific to each amino acid.
Answer: 23 chromosomes
In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23.

The percentage of the stroke volume is ejected during the first quarter of systole will be approximately 60% to 65%
<u>Explanation:</u>
The time interval between the atria contraction and the relaxation of ventricles are called as a Cardiac cycle. Systole denotes the heart contraction during the blood pumping. Diastole refers to the heart relaxation when the blood is filled in the heart chambers. The total blood is not fully pumped by the ventricles.
Instead they will pump only a proportion of blood in each of the cardiac cycle. The ejection fraction refers to the proportion of the intraventricular volume that is received as a output in circulation process. A human with normal heart functioning can have approximately 60-65%. This is known to be stroke volume. The blood volume that is ejected is strove volume.
