Answer:
Somatic hypermutation is a process in which point mutations build up in the antibody V-regions of both the heavy and light chains.
This process occurs at rates that are about 106-fold higher than the background mutation rates observed in other genes.
It allows B cells to mutate the genes that they use to produce antibodies. This then ensures the B cells to produce antibodies that are better able to bind to bacteria, viruses and other infections.
Based on the information in the table,
- the enzyme which is not functioning in the strain of mold is Enzyme Z which is responsible for the conversion of Citrulline to Arginine.
- the substance that would begin accumulating in the mold is Citrulline since it is not being converted to Arginine.
<h3>What are enzymes?</h3>
Enzymes are organic catalysts that speed up the chemical reactions occurring in the body.
Enzymes are very essential in most metabolic reactions occurring in the body.
The deficiency or inactivity of an enzyme in the body will lead to an accumulation of the substrate on which the enzyme acts on.

Answer:
One key way by which species evolve over time in response to changes in environmental conditions is adaptation by natural selection acting over generations. Characteristics that aid in effective survival and reproduction in the new environment grow more prevalent, while those that do not become less prevalent.
Explanation:
using subtraction to determine the volume dispensed
making sure that you read the volume with the liquid inside the pipette at eye level
ensuring that air bubbles are not in the column of liquid inside the pipette
C.they separate atria from ventricles, and ventricles from the large arteries that leave them.
