7. Cells that have stopped dividing and are differentiating are -

A. Cancer cellsB. In the S phase of the cell cycleC. In the G-1 phase of the cell

cycleD. In the M phase of the cell cycle

8. A cell spends the majority of its lifetime in which of the following?

A. Prophase B. Interphase C. Metaphase D. Mitosis

9. A photomicrograph of onion root tip cells during mitosis is shown to the right. Which phase of mitosis is occurring in the cell indicated by the arrow?

A. ProphaseB. MetaphaseC. AnaphaseD. Telophase

10.Samuel had a suspicious looking mole on his arm. He went to see Dr. Armstrong (a dermatologist) to have a biopsy done. When Dr. Armstrong looked at the skin cells under his light microscope he found a cell which had chromosomes lined up along the center of the cell. What phase of mitosis was the cell Dr. Armstrong was looking at in?

A. ProphaseB. Metaphase

C. AnaphaseD. Telophase

11.There are multiple checkpoints within the cell cycle. The purpose of these check points is to -

A. To assess whether the processes of each phase been accurately completed before moving into the next phase.

B. To make sure that S phase has been completed before entering into G1.

C. To make sure that the cell has tripled its DNA

D. To make sure the cytoplasm is hypertonic

12.Scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries. This bioengineered tissue is grown from living cells. The cellular process that enables the cells to grow and develop into tissue is —

A.conjugationB.meiosisC.BuddingD.mitosis

13.The model represents the change in the DNA content of a cell during the cell cycle.

Which part of the model represents the S phase?

A. IB. IIC. IIID. IV

18.When cells leave the cell cycle, they exit during G1 phase and then enter G0 phase, a resting period. Most normal cells can leave G0 phase and reenter the cell cycle at G1 phase before entering S phase.

A.Fail to complete S phaseB.Mutate during G1 phaseC.Repeat the cell cycle continuouslyD.Die after completing mitosis

19.Atherosclerosis is a disease that obstructs blood flow and, therefore, oxygen supply to target organs.
