The study of evolutionary phylogeny
relationships among organisms is
called ______.
The three cell types discussed, Last Universal Common Ancestor
eukaryotes, archaea, and bacteria,
all derived from ______.
Organisms called parasites are ______. always harmful to their host
Which of the following does not Thermal hot springs warmed by heat from earth's
indicate microbe involvement in interior
energy and nutrient flow?
The subatomic particles that Electrons
surround the nucleus are the ______.
The number one worldwide respiratory disease
infectious diseases are ______.
,A fat is called _____ if all carbons of saturated
the fatty acid chain are single-
bonded to 2 other carbons and 2
hydrogens.
One technique for staining bacteria lipid
for viewing under the microscope is
called the Gram stain. In this
technique, alcohol is used as a
decolorizer because it degrades
the outer membrane found in some
bacteria. What chemical
component of the cell does alcohol
affect?
If a microbiologist is studying a 95X
specimen at a total magnification of
950X, what is the magnifying power
of the objective lens if the ocular
lens is 10X?
NASA has published a list of criteria cell size of 0.5 to 2 microns
for identifying fossil bacteria in
samples from Mars, as part of a
search for evidence of life. Which of
the following is good evidence for
the presence of bacterial cells?
Which type of microscope achieves electron
the greatest resolution and highest
magnification?
Which of the following is produced a solid medium
by adding 1% to 5% agar to nutrient
broth that is then boiled and
cooled?
,a spongiform encephalopathy of Creutzfeldt-Jacob disease
humans
The term that refers to flagella at amphitrichous
both poles of the cell is ______.
In the condition called athlete's saprobe
foot, the fungus Trichophyton
consumes the keratin protein found
in hair, nails, and dead skin. Which
of the following descriptors does
not apply to Trichophyton?
During the Gram stain, the gram-negative
application of alcohol results in the
decolorization of ______ cells.
The size of a eukaryotic ribosome is 80s
______
Sterilizing filters have a pore size of Bacterial cells are typically between 1-10 μm and
0.22 μm. Which of the following are blocked by the filter, whereas most viruses
statements is true? are between 20 and 200 nm and therefore pass
through.
One of the principal viral capsid icosahedral
shapes is a 20-sided figure with 12
evenly spaced corners referred to
as a/an _____ capsid.
Amoebic dysentery is most fecal oral
commonly contracted through
the viral genome inserting into lysogeny
bacterial host chromosome
, Which of the following is not envelope
associated with every virus?
When bacilli in a chain fold back palisade
upon each other like a hinge, this
cellular arrangement is termed a
______.
proteins associated with DNA in the histones
nucleus.
Viral tissue specificities are called tropisms
______.
the term that refers to the presence lophotrichous
of a tuft of flagella emerging from a
single site is ______.
E. coli bacteria normally live in the mutualistic
human gut and produce vitamin K
that the body uses. This is best
termed a ______ relationship.
Termites are insects that require the mutualistic
protozoan Trichonympha in their
gut to synthesize the enzyme
cellulase to degrade the cellulose
in wood. The protozoan uses the
end products of the cellulose
breakdown (glucose). This is a(n)
______ relationship.
