The control of virus infection is complicated compared to bacteria since the virus   either enters into the host cells or used the host cell components to create new cells that is released to affect new cells. Hence it has been a challenge to isolate the virus particle and affect them with chemical components without causing damages to the host cells.

Hence antivirals are drugs that are designed to inhibit their activity. They will block the activity of the virus from entering the cells and make them into host. Hence D is the right option

shutvik [7]

Answer:

The hippocampus and the cerebrum are involved.

Explanation:

High analytical thinking, problem solving skills  and hard  reasoning - tasks (such as multiple-choice test) which involved high brain centers are designated to the  cerebrum in the frontal lobe. Therefore Zander will use this part of his brain to sort out the options, to reason to pick the best.

On getting the answer, this is  stored temporarily as short -memory in the Hyppocampus, before been integrated with old  information stored as old memories when he sleeps.

Thus the neural connectivity between the cerebrum and hippocampus form the basis of cognitive operations used by Zander,

If a researcher only wanted to examine the relationship between exercise and grade point average, _________ would be used to test the variables.

A.  correlation analysis

B.  regression

C.  hypothesis

D.  central tendency measures

Answer:

The correct answer would be - A. correlation analysis.
