MICROBIOLOGY REVIEW || VERIFIED QUESTIONS &
ANSWERS || HIGH-YIELD STUDY GUIDE ||
COMPLETE TEST BANK || GRADED A+
Microorganisms are involved in - CORRECT ANSWER -All are correct
The idea of Spontaneous Generation postulated that - CORRECT ANSWER
-living organisms could spontaneously arise from non-living material
Bioremediation refers to - CORRECT ANSWER -using bacteria to clean up
pollutants
Newly emergiing or re-emerging disease - CORRECT ANSWER -may be
due to changing lifestyles, exemplified by Lyme disease, toxic shock AND may
reflect a breakdown in sanitiation/social order
The prokaryotic cell scheme is found in - CORRECT ANSWER -Bacteria
AND Archaea
Which groups below contain single-celled and multicellular organisms? -
CORRECT ANSWER -algae AND fungi
The scientific name of an organism includes it - CORRECT ANSWER -
genus AND species
Eukaryotic cells are - CORRECT ANSWER -defined by the presence of a
membrane bound nucleus
,Which of the following stains is/are considered differential? - CORRECT
ANSWER -acid-fast stain AND Gram stain
THe cell wall of Gram-positive bacteria - CORRECT ANSWER -contains a
thick layer of peptidoglycan
THe proteins of bacteria that are involved in the movement of small molecules
into the cell, are called - CORRECT ANSWER -transport proteins,
permeases AND carriers
The macromolecule found in the cell walls of all bacteria is - CORRECT
ANSWER -peptidoglycan
Which of the following bacteria lack a cell wall? - CORRECT ANSWER -
mycoplasma pneumoniae
THe cell wall of Gram-negative organisms - CORRECT ANSWER -has a
thin peptidoglycan layer AND is characterized by an outer membrane
containing LPS
Endotoxin - CORRECT ANSWER -consists of LPS
The capsule - CORRECT ANSWER -maybe used for protection AND may
be used to help the bacteria adhere to surfaces
Which terms refers to bacterial morphology? - CORRECT ANSWER -
coccus AND bacillus
, THe cytoplasmic membrane of both eukayrotes and prokaryotes functions to -
CORRECT ANSWER -regulate movement of molecules which enter and
leave the cell
Facilitated diffusion and active transport - CORRECT ANSWER -both
transport molecules into or out of a cell
A newly developed antibiotic drug shows promise by inhibiting prokaryotic 70S
ribosomes in intial studies. However, when animal studies are begun, it's noted
that it also inhibits growth of animal cells. Aren't prokaryotic ribosomes
different from eukaryotic ribosomes? How can this be happening? -
CORRECT ANSWER -While the proteins made in the cytosol of eukaryotic
cells are, indeed, produced from the 80S eukaryotic ribosome, mitochondria and
chloroplasts possess 70S ribosomes. This drug might be impairing the activity
of mitochondria in animal cells
All the bacterial cells that result from the replication of a single original
bacterial organism are said to be a - CORRECT ANSWER -pure culture
Biofilms - CORRECT ANSWER -are a polysaccharide-encased community
of microorganisms, may enhance bioremediation efforts AND may portect
organisms against harmful chemicals
THe simplest technique for isolating bacteria in growth media is referred to as
the - CORRECT ANSWER -streak plat method
In the growth curve of a bacteria population, the bacteria are rapidly increasing
in number in th - CORRECT ANSWER -exponential (log) phase
During which phase of growth are bacteria most susceptible to antibiotics? -
CORRECT ANSWER -Exponential (log Phase)
