Such changes would occur mostly likely near or in the active binding site of the enzyme.
Because the drugs used are competitive inhibitors of the <span>HIV reverse transcriptase enzyme, it means that they connect directly to the active binding site of this enzyme not allowing it to preform its function. If the mutations impede this drugs to work, it is probably because they alter the active binding site of the enzyme, not allowing the drug to bind and have its competitive behaviour permitting the enzyme to work normally. </span><span /><span>

Answer:
Respiratory system and circulatory system.
The respiratory system allow living things to obtain oxygen from the air while the circulatory system allows oxygen to be carried around the body.
A gene pool changes throughout evolution this could be natural selection, genetic drift or a mutation. A gene pool does this to adapt with the needs of the environment it is in
from the way it was created
