What are CD4+ cells?
telo118 [61]
The answer is <span>B.  immune cells that are destroyed by HIV 

CD4+ are immune cells (white blood cells) and are an important part of the immune system. Their name comes from the presence of CD4 glycoprotein on their surface. HIV uses CD4 glycoproteins on the surface of CD4+ cells to entry into the cells. The consequence is a reduced number of those cells. Therefore, CD4+ immune cells are destroyed by HIV.</span>

Determine whether the statement is true or false. Suppose P(t) represents the population of bacteria at time t and suppose P'(t)
Lorico [155]

Answer:

TRUE

Explanation:

If the population follows a logistic growth curve, the graph of P vs t will look like the diagram below.

The rate of growth (P') increases slowly at first, then increases rapidly from 2 to 4, and then slows down, but always P > 0.

The graph has an inflection point at (3, 1000). That's the point at which the rate of growth starts slowing down.

When t < 3, P'' > 0.  

When t = 3, P'' = 0.

When t > 3, P'' < 0, because the rate of population growth is slowing down.

Thus, if the population is in the final phase of logistic growth, the population is increasing at a decreasing rate (TRUE)..
