2. A researcher is looking to determine the source of contamination of a patient that
presented with symptoms of food poisoning. To best determine between E. coli
or Salmonella as the cause, what type of agar will be used to isolate the growth
of each?
- ANSWER: Differential Media
3. Also known as lysogeny broth, it is a multi - purpose media capable of growing a
wide variety of microorganisms.
- ANSWER: LB Agar
4. Amoeba
- ANSWER: Eukaryote
5. Archaeon
- ANSWER: Prokaryote
6. Autotroph
- ANSWER: Obtain their source of carbon from inorganic molecules
7. Bacteria that have a curved rod morphology are referred to as
- ANSWER: Vibrio
8. Briefly explain how a Scanning Electron Microscope (SEM) forms an image of
subcellular organelles, substrates, and viral particles.
- 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.

- ANSWER: Yersinia pestis
10. Can provide detailed images of live cells without staining .
- ANSWER: Phase Contrast Microscope
11. Chemotroph
- ANSWER: Acquire energy from
12. Chloroplasts
- ANSWER: Site of photosynthesis

13. Combines the usefulness of fluorescence microscopy with the ability to visualize
cells in 3 - D
- ANSWER: Confocal Microscope
14. Describe the ONE main differences between lytic and temperate phages.
- ANSWER: Lytic bacteriophages replicate within the host bacteria until it
ruptures whereas temperate (or lysogenic) phages primarily exist
in a non - replicative state that does not kill the host cell.
15. Describe TWO differences between DNA and RNA.
- ANSWER: RNA contains the sugar ribose rather than deoxyribose. RNA is
always single - stranded, whereas DNA is double stranded
16. E. Coli - ANSWER: Prokaryote
17. Each of the following statements about glycolysis is true, except:
- ANSWER: The net gain is 4 ATP
18. Each of the following statements about measles, mumps, and rubella is true,
except.
- ANSWER: Infect the CNS (central nervous system), leading to temporary or
permanent paralysis
19. Endoplasmic Reticulum
- ANSWER: Series of membrane-enclosed sacs and interconnected tubes
20. Giemsa staining is used to detect each of the following, except:
- ANSWER: Neisseria Gonorrhea
21. Identify the following disease based upon the physical manifestation:
- ANSWER: Anthrax
22. Incoming light is in the form of the ultraviolet (UV) spectrum.
- ANSWER: Fluorescence Microscope

to which of the following?
- ANSWER: Rheumatic fever
24. Legionnaires
- ANSWER: Legionella
