WGU D311 EXAM SCRIPT VERIFIED
QUESTIONS WITH COMPLETE SOLUTION
REVIEW
●● What is the significance of the molecule that makes up the bilayer
formed in the plasma membrane of most bacterial and eukaryotic cells?
Answer: Phospholipids help maintain hydrophobic and hydrophilic
environments.
●● Which microorganisms produce dermatophytes that can cause skin
infections, such as athlete's foot and ringworm?
Answer: Fungi
●● Which microorganisms can produce human pathogens that spread via
microsporidia?
Answer: Fungi
●● Why are archaea considered prokaryotic organisms?
Answer: Their cells do not contain a nucleus.
●● Why is MRSA more pathogenic than other strains of Staphylococcus
aureus?
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?
Answer: Iatrogenic
●● Which viral virulence factor requires adjustments to the influenza
vaccine annually?
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?
Answer: Coagulase and kinase
●● How does coinfection of a single cell by multiple strains of a virus
increase it's pathogenicity?
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.
