The last one, I believe.
This is a male, with three copies of chromosomes 21
Hope it helps :D
Answer:
See the explanation below. Thanks!
Explanation:
The structure of an amino acid allows it to act as both an acid and a base. An amino acid has this ability because at a certain 
value (different for each amino acid) nearly all the amino acid molecules exist as zwitter-ions. If acid is added to a solution containing the zwitter-ion, the carboxylate group captures a hydrogen (
) ion, and the amino acid becomes positively charged. If base is added, ion removal of the ion from the amino group of the zwitter-ion produces a negatively charged amino acid. In both circumstances, the amino acid acts to maintain the pH of the system—that is, to remove the added acid 
or base 
from solution.
They form into more molecules as they produce more
The nutrient is phosphorus
<h3>The phosphorus cycle</h3>
Phosphorus cycles between living components of the earth (biosphere) and the soil (geosphere).
The element's reservoir is mainly the sediments of the ocean and rocks. Phosphorus gets into the soil by weathering of rocks.
Plants are able to pick the element up from the soil and animals are able to get their phosphorus by consuming plants.
When plants and animal die, their body decomposes and the phosphorus in them enters the soil.
Thus, the cycle being referred to in the illustration is the phosphorus cycle.
