verified answers passed
Dr. Strummer has discovered a new ovoid (oval-shaped) microorganism that is 1um in diameter.
The organism's genome is a single circular chromosome. The new microorganism is: - correct
answer ✔✔a bacteria
Which of the following is the correct way of writing the genus and species name of a bacteria: -
correct answer ✔✔Escherichia coli (italics)
When examining the evolution of life on Earth, scientists find that at the genetic level
eukaryotes are more similar to organisms in the kingdom _______ than organisms in the
kingdom ________. - correct answer ✔✔Archaea, Bacteria
Pasteur's Experiments with Swan Neck Flasks disproved which of the following theories on the
origin of microorganisms: - correct answer ✔✔Spontaneous Generation
Which of the following activities is NOT an activity observed in living cells? - correct answer
✔✔All cells communicate with other cells.
The correct ones:
All cells grow.
All cells metabolize.
all cells evolve
Dr. Strummer is examining a new microorganism isolated from the permafrost of Siberia.
Transmission electron micrographs show a unicellular organism 100um in diameter. The
organism appears to have a nucleus, membrane bound organelles, and a cell wall. What would
,you predict is the main chemical component of this organism's cell wall? - correct answer
✔✔cellulose or chitin
The germ theory of disease refers to: - correct answer ✔✔the theory that some human diseases
are caused by microorganisms that have gained access to the human body.
_____________ refers to the evolutionary relationships between organisms deduced through
the comparison of their genetic material. - correct answer ✔✔Phylogeny
Uncle Billy Bob is nervous. Three of his prize winning roosters, Huey, Dewey, and Louie, at Billy
Bob's Ranch for Interesting Chickens have developed sores on their beaks consistent with a
condition called beak rot. Dr. Strummer visits the ranch, takes samples from the sores of the
three diseased chickens, and brings the samples back to his research lab. He isolates bacteria
from the each sample (Huey, Dewey, and Louie) and grows them in three SEPARATE culture
tubes. He then injects aliquots (small portions) of each diluted culture into the backs of 5
healthy laboratory chickens that are sterile and lack any disease immunity. After 3 days the
laboratory chickens injected with bacteria cultured from the samples of Huey and Dewey have
sores on their beaks similar to those observed in Huey and Dewey. Chickens injected with
bacteria cultured from the samples of Louie are perfectly healthy.Is the cause of Huey's beak rot
- correct answer ✔✔Yes, because bacteria isolated from Huey's sore sample were able to cause
sores in laboratory chickens consistent with Koch's 3rd postulate.
Which of the following outcomes of a human encounter with a microorganism is NOTtrue? -
correct answer ✔✔The colonizing microorganism will always cause disease in the human.
True:
The human may be permanently colonized with the microorganism.
The human may be transiently colonized with the microorganism.
The colonizing microorganism may cause disease in the human.
The genome of COVID-19 is composed of: - correct answer ✔✔single stranded RNA
, A ________ is smaller than a _______ which, in turn, is smaller than a ________. - correct
answer ✔✔virus, bacteria, human cell
The capsid of COVID-19 has ___________ symmetry and functions to _________________. -
correct answer ✔✔helical, protect the viral genome
COVID-19 replicates in cells found in the - correct answer ✔✔upper and lower respiratory tract
Which of the following is NOT a clinical diagnostic test utilized for diagnosis of COVID-19
patients? - correct answer ✔✔Viral Culture and Enumeration Test
____________ is defined as the smallest distance by which two objects can be separated and
still be distinguished. - correct answer ✔✔resolution
Compared to Eukaryotes, Bacteria and Archaea have ________ surface-area-to-volume ratios,
causing ________ nutrient exchange and growth rates. - correct answer ✔✔higher, faster
Rod shaped bacteria arranged in chains are referred to as: - correct answer ✔✔Streptobacilli
True or False: Cell morphology can be used to predict the physiology, ecology, and phylogeny of
a prokaryotic cell. - correct answer ✔✔False
Dr. Strummer would like to use microscopy to observe the chemotaxis of the living Escherichia
coli cells. Which microscopy technique would be most appropriate? - correct answer ✔✔Bright-
field Microscopy of an unstained sample.
Which of the following statements is NOT true about the use of staining in microscopy? - correct
answer ✔✔Staining is used to to increase the resolving power of a microscope.
