Questions With Correct Answers
Which class of cells most often contain extrachromosomal DNA found in
| | | | | | | | | |
plasmids? - CORRECT ANSWER✔✔-Prokaryotic
| | | |
What is the significance of the molecule that makes up the bilayer
| | | | | | | | | | | |
formed in the plasma membrane of most bacterial and eukaryotic cells?
| | | | | | | | | |
|- CORRECT ANSWER✔✔-Phospholipids help maintain hydrophobic and
| | | | | | |
hydrophilic environments. |
Which microorganisms produce dermatophytes that can cause skin
| | | | | | | |
infections, such as athlete's foot and ringworm? - CORRECT
| | | | | | | | |
ANSWER✔✔-Fungi
Which microorganisms can produce human pathogens that spread via
| | | | | | | | |
microsporidia? - CORRECT ANSWER✔✔-Fungi | | |
Why are archaea considered prokaryotic organisms? - CORRECT
| | | | | | | |
ANSWER✔✔-Their cells do not contain a nucleus. | | | | | |
, Why is MRSA more pathogenic than other strains of Staphylococcus
| | | | | | | | | |
aureus? - CORRECT ANSWER✔✔-MRSA has increased antibiotic
| | | | | | |
resistance.
A patient recently had an outpatient surgical procedure. After a few
| | | | | | | | | | |
days at home, they noticed swelling and redness at their incision site.
| | | | | | | | | | | |
How would this infection be classified? - CORRECT ANSWER✔✔-
| | | | | | | |
Iatrogenic
Which viral virulence factor requires adjustments to the influenza
| | | | | | | | |
vaccine annually? - CORRECT ANSWER✔✔-Antigenic variation
| | | | |
Which pair of enzymes are produced by some bacteria that causes the
| | | | | | | | | | | |
clotting of blood to protect the bacteria in the bloodstream, then a
| | | | | | | | | | | |
digestion of the clots to allow the bacteria to spread? - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-Coagulase and kinase | |
How does coinfection of a single cell by multiple strains of a virus
| | | | | | | | | | | | |
increase it's pathogenicity? - CORRECT ANSWER✔✔-Coinfection
| | | | | |
provides the opportunity for an antigenic shift.
| | | | | |
Canned food is heated and sealed in sterile containers to provide a
| | | | | | | | | | | |
longer shelf life and prevent spoilage. Improper canning results in the
| | | | | | | | | | |
growth of microorganisms, which may result in food containers that
| | | | | | | | | |
swell and explode.
