a solid medium - Which of the following is produced by adding 1% to 5% agar to nutrient broth that is
then boiled and cooled?
Creutzfeldt-Jacob disease - a spongiform encephalopathy of humans
amphitrichous - The term that refers to flagella at both poles of the cell is ______.
saprobe - In the condition called athlete's 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?
gram-negative - During the Gram stain, the application of alcohol results in the decolorization of ______
cells.
80s - The size of a eukaryotic ribosome is ______
Bacterial cells are typically between 1-10 μm and are blocked by the filter, whereas most viruses are
between 20 and 200 nm and therefore pass through. - Sterilizing filters have a pore size of 0.22 μm.
Which of the following statements is true?
icosahedral - One of the principal viral capsid shapes is a 20-sided figure with 12 evenly spaced corners
referred to as a/an _____ capsid.
fecal oral - Amoebic dysentery is most commonly contracted through
lysogeny - the viral genome inserting into bacterial host chromosome
envelope - Which of the following is not associated with every virus?
,palisade - When bacilli in a chain fold back upon each other like a hinge, this cellular arrangement is
termed a ______.
histones - proteins associated with DNA in the nucleus.
tropisms - Viral tissue specificities are called ______.
lophotrichous - the term that refers to the presence of a tuft of flagella emerging from a single site is
______.
mutualistic - E. coli bacteria normally live in the human gut and produce vitamin K that the body uses.
This is best termed a ______ relationship.
mutualistic - Termites are insects that require the 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.
lag phase - The phase of the bacterial growth curve in which newly inoculated cells are adjusting to their
new environment, metabolizing but not growing at an exponential rate, is the ______.
hypotonic - The cell wall will help prevent the cell from bursting in ______ conditions.

compounds as an energy source. Its carbon source is an organic compound. The appropriate
classification for this organism would be ______.

deletion and insertion - A frameshift is caused by ______ mutations.
genomics refers to the study of an organism's entire genome, whereas proteomics is the study of
expressed proteins - The fields of genomics and proteomics differ in that
eukaryotes - endosymbiotic theory
