bacterial samples from each company onto MSA agar. After incubating the
samples overnight at 37°C., briefly explain how he will interpret the result of
his samples. - ANSA sample showing only colorless colonies growing on red
agar would indicate the presence of non-pathogenic bacteria, while a sample
showing a distinct yellow agar would indicate the presence of Staph aureus.
True or False: Leprosy can move through the blood to other areas including
the brain, spine, and kidneys. - ANSFalse: TB is primarily considered a
respiratory infection, but once it fully colonizes the lungs, TB can move
through the blood to other areas including the brain, spine, and kidneys.
True or False: Proteins can function to catalyze biochemical processes and
play a role in structure, but they cannot enable movement. - ANSFalse.
Proteins can function to catalyze biochemical processes, play a role in
structure, and they can enable movement.
True or False: The metabolism of a lipid-derived carbon atom will yield more
ATP than a molecule of glucose. - ANSTrue

conditions? - ANSA facultative anaerobe is capable of growth under both
aerobic & anaerobic conditions.
As Streptococcus is catalase negative would it thrive or die in the
presence of peroxides? Why? - ANSDie.
Steptococcus is catalase negative and is unable to breakdown peroxides,
therefore, it would die in the presence of peroxides.
Define commensal bacteria. - ANSIt doesn't harm or benefit the host from
which it obtains it's nutrients.
Define the concept of universal precautions. - ANSUniversal precautions is
