PORTAGE LEARNING 2025 BIOD 171 ESSENTIAL MICROBIOLOGY
FINAL EXAM | VERIFIED ANSWER (100% CORRECT) | LATEST
UPDATE
Nucleus - CORRECT ANSWER - contains genomic content in eukaryotic
cells
Endoplasmic reticulum - CORRECT ANSWER - series of membrane enclosed
sacs and interconnected tubes
Lysosomes - CORRECT ANSWER - contain hydrolytic enzymes for digestion
Chloroplast - CORRECT ANSWER - Site of photosynthesis
Briefly explain how a Scanning Electron Microscope (SEM) forms an image of
a microscopic specimen. - CORRECT ANSWER - Answer: An image is
formed from the interactions of electrons as they reflect off (not through) the
surface of the specimen. Samples are coated in either gold or palladium to
enhance electron reflections. The reflection is seen in 3-D rendering.
Legionnaires - CORRECT ANSWER - legionella
Wound botulism - CORRECT ANSWER - Clostridium botulinum
Impetigo - CORRECT ANSWER - staph auerus
Septicemic plague - CORRECT ANSWER - yersina pestis
Yeast - CORRECT ANSWER - Eukaryote
, Mycobacterium - CORRECT ANSWER - Prokaryote
Algae - CORRECT ANSWER - Eukaryote
flu virus - CORRECT ANSWER - neither eukaryote or prokaryote
Phototroph - CORRECT ANSWER - utilize photons to generate ATP from
ADP
lithotroph - CORRECT ANSWER - remove electrons from inorganic
molecules
autotroph - CORRECT ANSWER - obtain their source of carbon from
inorganic molecules
chemotroph - CORRECT ANSWER - acquire energy from preformed
chemicals in the environment
A researcher is looking to solidify an agent for growth media. What
polysaccharide substance would he or she use? - CORRECT ANSWER - agar
Place the following viral life cycle steps in order beginning with viral
attachment (3points) and provide a description of "UNCOATING" (1 point). -
CORRECT ANSWER - 1-Attachment:
2-Entry:
3- Uncoating: the viral capsid disassembles
