Food web only contains interactions between trophic levels while an interaction web shows both trophic and non-trophic interactions.
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.
Answer:
the answer is juvenile
Explanation:
Turtles' life cycles progress from being an egg, hatchling or baby turtle, into being a juvenile.
Answer:
They use them so that they can see what type of organisms live there.
Explanation:
1. True.
2. Given: Mass = 30 Kg
Acceleration = 2.0m/s2
Force= mass x acceleration
Force= 30Kg x 2.0 m/s2
Force= 120 N
3. Given : Mass = 30 Kg
Force= 180 N
Force = Mass x Acceleration
Acceleration = Force / Mass
= 180 N / 30 Kg
Acceleration = 6.0 m/s2
