and that all cells are descended from other cells. (B) the organelle hypothesis. Cell theory (C). D)
the passing on of acquired traits. In response, choose CTopic: 4.1Skill: Information.

thousand times. Which of the following would be the best instrument? an electron transmission
microscope B) an electron scanning microscope A fluorescent confocal microscope is option C.
A flipped light microscope (option D) Response: BTopic: 4.1 Implementation and assessment

transmission electron microscope. A) Dead cells and living cells B) internal cell structures and
cell surfaces D) Live cells versus dead cells D) cell surfaces and interior cell structures In
response, choose topic: 4.1Skill: Expertise
10) The majority of animal and plant cells have a diameter betweenA) 0.1 and 1.0 micrometers.
B) From 1.0 to 10 microns. C) Ten to one hundred microns. D) 100–1000 microns. Response:
CTopic: 4.1 Skill: Understanding/Knowledge
11) Surface area and volume decrease as cell size rises. A) Volume grows more quickly than
surface area. C) Surface area grows more quickly than volume. D) the volume and surface area
grow at the same pace. Respondent's choice: BTopic: 4.2Skill: Knowledge/Comprehension
12) What cell has the highest surface-to-volume ratio among the others?
A bacteria B a red blood cell of a human
Human muscle cell (C)
Ostrich egg (D)
Response: A
Skill: Knowledge/ComprehensionSubject: 4.2
13) A chemical is introduced to a cell that inhibits it from dividing. The cell keeps becoming
bigger. The cell can continue to carry out all other important tasks, therefore this situationA)
shouldn't cause it any problems. B) shouldn't pose any issues for the cell since as the cell's
volume rises, its surface area will as well. As the cell's capacity to take nutrients through its outer
membrane won't keep growing as quickly as its cytoplasmic demands, option C) will ultimately
present an issue. The cell will be able to direct the ATP typically needed for cell division to other
functions, which should be advantageous for D). 4.2Skill: Assessment CTopic: 4.2
14) You want the final cough drop in the box to stay in your mouth for a long period since your
throat feels dry. What ought you to do? A) Cut the cough drop into little pieces and ingest them
all. Because each tiny particle needs to disintegrate on its own, the drop will remain longer. B)
Save the entire cough drop. This keeps the highest surface-to-volume ratio and inhibits the cough
drop's disintegration. D) Cut the cough drop into little pieces and ingest them all. This lowers the
surface-to-volume ratio and inhibits the cough drop's disintegration. D) The quantity of the
cough drop itself is what matters, not whether it is in one piece or many portions. Solution:
BTopic: 4.2Skill: Assessment
