Hint:think about the direction of movement caused by stress
Shkiper50 [21]

Answer:

Compression is a reverse fault, tension is normal fault and shear is strike slip fault.

Explanation:

Compression is a reverse fault, tension is normal fault and shear is strike slip fault. Reverse fault is opposite of normal fault which occurs due to the stress of compression on an object in which both object come close together. Due to tension stress, rocks pulling apart from each other, produces a normal fault. Shear is strike slip fault because in strike-slip fault, the two blocks slide over one another

According to slide 12, what is the relationship between opportunistic infections and the number of T cells a person has? Explain
podryga [215]

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.
