Animalia, Plantae, Fungi and Protista are all classification under what type of
organism?
A. Bacteria
B. Eukarya
C. Archaea
D. Virus ---------CORRECT ANSWER-----------------B. Only Eukarya contains animals,
plants, fungi and protists.
True or False: All multicellular microorganisms classified as Animalia are
autotropic. ---------CORRECT ANSWER-----------------False
True or False. To restrict the growth of a pathogenic microbe a researcher might
decrease an incubator from 37°C to 25°C. ---------CORRECT ANSWER-----------------
True
When given an unknown bacterial sample the first step is to expand the current
bacterial population. Which form of media best suites this need? Why? ---------
CORRECT ANSWER-----------------LB media because all of the other forms are
,selective media meaning they may potentially inhibit the growth of the unknown
sample.
What is cellular metabolism? ---------CORRECT ANSWER-----------------Metabolism is
a controlled set of biochemical reactions that occur in living organisms in order to
maintain life.
True or False. Only directly ingesting the pre-formed clostridium toxin (neither the
bacteria nor its spores) will cause disease in adults. ---------CORRECT ANSWER------
-----------True
True or False. There are currently no cures for tetanus. ---------CORRECT ANSWER--
---------------True
What is the primary function of enzymes, and how are they regulated? ---------
CORRECT ANSWER-----------------Enzymes speed up chemical reactions. Most
notably, the enzyme is not consumed during the reaction and can be used
repeatedly by the cell. Enzymes can also be regulated by a cofactor such that in
the absence of the proper cofactor, enzymes are inactive while in its presence
enzymes are active.
The alpha-toxin perfringolysin is associated with which medical condition caused
by Gram-positive anaerobic bacteria?
,A. Gas gangrene
B. Tetanus
C. Leprosy
D. Botulism ---------CORRECT ANSWER-----------------A.
True or False. Bubonic plague is often characterized by painfully swollen lymph
nodes. ---------CORRECT ANSWER-----------------True
True or False. Chlyamida is an obligate parasite and as such can be grown on agar
plates alone. ---------CORRECT ANSWER-----------------False
What is the difference between catabolism and anabolism? ---------CORRECT
ANSWER-----------------Catabolism is the process of breaking down larger molecules
into useful energy sources whereas anabolism is the building up or biosynthesis of
macromolecules from smaller molecular units into larger complexes, most often
associated with cellular growth and repair.
True or False. Similar to chickenpox, the blisters that appear with shingles can
cover the entire body. ---------CORRECT ANSWER-----------------False
, What linear, double-stranded, enveloped DNA virus is the first virus (as of Oct. 26,
1977) to be officially declared eradicated? ---------CORRECT ANSWER-----------------
Smallpox also known as variola virus
ATP has the energy to________, while ADP has the capacity to _______energy. ---
------CORRECT ANSWER-----------------Answer 1: Donate Answer 2: Accept
By whom and where was the first polio vaccine developed? ---------CORRECT
ANSWER-----------------By Jonas Salk at the University of Pittsburgh
A drug company is trying to develop a new drug that will inhibit viral entry of
Influenza. Would the drug company target hemagglutinin proteins or
neuraminidase proteins? Why? ---------CORRECT ANSWER-----------------
Hemagglutinins because hemagglutinins are involved in entry of viral particle into
a host's cell. Whereas, neuraminidase is involved in budding and relase of the new
viral particles from the host cell.
Which of the following are considered Protista? Select all that apply.
A. Amoeba
B. Algae
C. Yeast
D. Bacteria ---------CORRECT ANSWER-----------------A & B
