Question 6

A team of researchers is studying the external structures on the dorsal (back)  surface of a spider mite. The spider mite seems to be the habitat of an even smaller mite, which is approximately 0.05mm. While they can see the dorsal surface of the spider mite with their naked eye, they cannot see the mite clearly. The researchers are writing a grant to provide support for a microscope to use to study these new mites. They need to purchase a microscope with a high magnification to observe the new mites on their habitat. It is not necessary for them to observe living mites. Based on the information given, what type of microscope would you suggest?

Accepted Answer

A)   scanning electron microscope
B)   transmission electron microscope
C)   dissecting microscope
D)   binocular compound light microscopeE) C) and D)
F) None of the above

Question 7

Many antibiotics selectively kill bacteria and not mammalian cells because they block synthesis of the _______.

Accepted Answer

A)   nucleus
B)   cytoskeleton
C)   cytoplasm
D)   cell wall
E)   plasma membraneF) C) and D)
G) A) and E) D

Question 8

A cytologist is examining a tissue under an electron microscope. He notices that the endoplasmic reticulum of each cell is extremely rough in appearance and he knows that the rough appearance is because of the ribosomes embedded there. He asks why there are so many ribosomes. You respond,

Accepted Answer

A)   "This tissue exports lipids and is very involved with mRNA production."
B)   "This tissue exports proteins to other areas of the body."
C)   "This tissue exports various nucleic acids, hence the large number of ribosomes present on the endoplasmic reticulum in each of those cells."D) A) and C)
E) B) and C)

Question 9

If the function of centrioles was impaired in a cell, it could not:

Accepted Answer

A)   produce lysosomes.
B)   conduct photosynthesis.
C)   make ATP.
D)   synthesize proteins.
E)   divide.F) B) and D)
G) D) and E) E

Question 10

A protein that is destined to reach the plasma membrane is making its way through the Golgi. At that moment, a drug was added to cells, blocking trafficking at the trans face of the Golgi. As a result, what would happen to the protein?

Accepted Answer

A)   The protein would continue on to the cell surface.
B)   The protein would be stuck in the Golgi.
C)   The protein would return to the ER via the cis face of the Golgi.
D)   The protein would exit the Golgi, but instead be targeted to the cytoplasm.E) C) and D)
F) A) and D)

Question 11

Cells that produce a lot of lipids for membranes would have an enlarged

Accepted Answer

A)   nucleus.
B)   smooth ER.
C)   Golgi body.
D)   mitochondrion.
E)   rough ER.F) A) and E)
