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
