1. Bacteria that form a cluster of spheres are called: a. | Bacilli | b. | Diplococcic | c. | Staphylococci | d. | Streptococci |
2. An anaerobe requires which specific environment? a. | a dry environment | b. | an acidic medium | c. | air at temperature less than 61° F/16° C | d. | the absence of oxygen |
3. The presence of the bacterial capsule: a. | promotes attachment of the bacteria to tissue | b. | protects the microbe from phagocytosis | c. | increases the release of toxins and enzymes | d. | prevents replication of the bacterium |
4. Microbial mutation means that: a. | genetic information and some microbial characteristics have changed | b. | pathogens become nonpathogens | c. | the microbe survives adverse conditions but can no longer replicate | d. | the immune response to that microbe is strengthened |
5. A bacterial endospore can: a. | also be classified as an acid-fast bacterium | b. | exist in latent form inside a host cell | c. | reproduce very rapidly | d. | survive high temperatures and dry environment |
6. The structure of a virus includes: a. | a cell wall and membrane | b. | metabolic enzymes for replication | c. | a protein coat and either DNA or RNA | d. | a slime capsule and cilia |
7. What method do viruses use to replicate? a. | binary fission | b. | budding of a daughter cell from the parent viral cell | c. | producing reproductive spores | d. | using a host cell to produce and assemble components |
8. A retrovirus such as HIV contains: a. | RNA and enzymes for its conversion | b. | a double strand of DNA | c. | many enzymes to limit budding of new virions | d. | numerous mitochondria |
9. How do antiviral drugs act? a. | interfering with cell wall development | b. | decreasing cell membrane permeability |
