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.

Answer:
They can be harmful.
Explanation:
Prokaryotes are the organism that do not have nucleus and lacks the membrane bound organelle. Eukaryotes have well defined nucleus and contains the membrane bound organelle.
Th prokaryotes includes the small bacteria and other small organism. The bacteria can cause harmful disease in humans. They can cause cancer or can mutate the genetic constitution of the organisms. The prokaryotes can destroy the products that are harmful and their consumption can destroy the human health.
Thus, the correct answer is option (3).
There is an uneven distribution of electrons between oxygen & hydrogen atoms
