Accepted Answer

Viruses are characterized by having a protective protein coat called a capsid and being only able to replicate in a living host cell.

Question 11

The higher the viral load the more likely the patient will display signs and symptoms of the viral illness.

Accepted Answer

This is true. The viral load is a measure of the amount of virus present in the body and is often correlated with the severity of symptoms. A higher viral load means there are more viruses replicating in the body, which can lead to more severe symptoms.

Question 12

Identify all answer choices that best complete the question. How do viruses cause disease?

Accepted Answer

Viruses cause disease by either shutting down or destroying a cell (lysis) or by reproducing within the cell and then breaking open to infect other cells. They do not necessarily infect the nervous system and do not live on or in another organism in a parasitic sense.

Question 13

Select the best response to the question. How do antifungal agents work?

Accepted Answer

Antifungal agents work by inhibiting the production of ergosterol, a component of fungal cell membranes that is necessary for their survival. Without ergosterol, the cell membrane becomes unstable and the fungus is unable to grow or reproduce.
