Answer to Question 1

B

Answer to Question 2

A
Feedback:
HIV is an infectious human retrovirus that invades a healthy, normal cell. The virus uses its own RNA to change the healthy cell's existing DNA into cells that replicate. The virus overtakes the biosynthesis of existing cells to duplicate and spread HIV within the body. A reverse transcriptase enzyme is necessary to convert the virus's RNA into DNA. HIV cells are created and are then able to reproduce new HIV cells. The original purpose or function of the normal cell is destroyed.
