Answer:
The fewer number of T cells a person has, the more chances to be affected by an opportunistic infection. When the number of T cells reaches 200 cells/µl, the person is at risk of being infected by other infections.
Explanation:
The whole immune system of a person who is infected with HIV infection seems to be severely affected. When the person is not treated or the disease is in a very advanced stage, the depletion of the T- cells turns to be very sharped, especially CD4+ T cells. At this point, the immune system can not resist the attack of other microorganisms. The <em>lower is the number of CD4+ T Cells, the higher possibility the person has to be attacked by opportunistic infections. </em>
Classically, it has been suggested that opportunistic infections appear after the CD4 + T lymphocytes reach very low levels, such as 200 cells/µl. The number of circulating T cells can be used as an indicator and a measure of global "immune competence", and the previously mentioned amount of CD4 + T cells is an accepted universal reference used to predict the risk of having one of these opportunistic infections.

Explanation:
Answer:
the animal cell will burst
Explanation:
If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.
Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.
Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.
