1. Nucleus: contains genomic content in eukaryotic cells | | | | | |
2. Endoplasmic reticulum: series ofmembrane enclosed sacs and interconnected | | | | | | | |
tubes
|
3. Lysosomes: contain hydrolytic enzymes for digestion | | | | |
4. Chloroplast: Site of photosynthesis | | |
5. Briefly explain how a Scanning Electron Microscope (SEM) forms an image of
| | | | | | | | | | |
a microscopic specimen.: 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.
| | | |
6. Legionnaires: legionella |
7. Wound botulism: Clostridium botulinum | | |
8. Impetigo: staph auerus | |
9. Septicemic plague: yersina pestis | | |
10. Yeast: Eukaryote |
11. Mycobacterium: Prokaryote |
12. Algae: Eukaryote |
13. flu virus: neither eukaryote or prokaryote
| | | | |
14. Phototroph: utilize photons to generate ATP from ADP | | | | | | |
15. lithotroph: remove electrons from inorganic molecules | | | | |
16. autotroph: obtain their source of carbon from inorganic molecules | | | | | | | |
17. chemotroph: acquire energy from preformed chemicals in the environment | | | | | | | |
18. A researcher is looking to solidify an agent for growth media.What poly-
| | | | | | | | | | | |
saccharide substance would he or she use?: agar
| | | | | | | |
19. Place the following viral life cycle steps in order beginning with viral
| | | | | | | | | | |
attachment (3points) and provide a description of "UNCOATING" (1 point).: - 1-
| | | | | | | | | | | |
Attachment:
2- Entry:
3- Uncoating:the viral capsid disassembles | | | |
4-Replication:
|
5- Release:
6- New infection: |
20. The action of alcohol during Gram staining is
| .:Decolorizes the
| | | | | | | |
cell
|
21. Left untreated, three percent of cases of Streptococcal pharyngitis will
| | | | | | | | |
progress to which of the following?: Rheumatic fever
| | | | | | | |
22. DescribeTWO differences between DNA and RNA.: Answer: Any of the fol- | | | | | | | | | | |
lowing are acceptable answers:RNA contains the sugar ribose rather than deoxyri-
| | | | | | | | | | | |
bose.RNA is always single-stranded, whereas DNA is double-stranded.While RNA
