Question 4

Infectious agents such as:

viruses always have a protein coat and a nucleic acid (DNA or RNA)

bacteria usually are intracellular (found inside of cells)

prions are easy to treat because they are denatured proteins

protozoans are single-celled prokaryotes

fungi are usually multicellular and large if they infect and cause human disease

Explanation / Answer

A is the correct answer.

B. Bacteria can be intracellular or extracellular. Though some are obligate intracellular, but many bacteria are free living and live in the soil, water or air.

D. Protozoans are single-celled eukaryotes.

E. Though most of the fungi are multicellular, some are unicellular and they are never large,
