Some single-celled organisms make copies of themselves through mitosis. Which decribes the
function of the cell cycle in such single-celled organisms?
Imagine that a disorder that causes the cell cycle to stop affects the muscle cells of a frog's leg. What
consequence is most likely to follow?
The frog will not be able to hop using that muscle.
An injury to the muscle will not heal.
The frog will not be able to reproduce.
A broken bone in that leg will not mend. - ANSWER: An injury to the muscle will not heal.
Skin cells are lost daily even without injury. Which best describes the purpose of the cell cycle for skin
cells in this circumstance?
Each year, about 1.2 million cases of skin cancer are reported worldwide. An increased exposure to
environmental conditions is a major link to the increase in cases. Based on this information, which is
the best conclusion?
Limiting exposure to the sun may increase the chance of skin cancer.
Increasing exposure to the sun may reduce the chance of skin cancer.
Increasing exposure to the sun will not affect the chance of skin cancer. - ANSWER: Limiting exposure
to the sun may reduce the chance of skin cancer.
What is the purpose of interphase in the eukaryotic cell cycle?
The diagram shows the stages of the eukaryotic cell cycle.
Which stage is labeled E in the diagram?
mitosis
interphase
S phase
G0 phase - ANSWER: Interphase
The diagram shows the stages of the eukaryotic cell cycle.
Which stage is labeled C in the diagram?
M phase
G0 phase
,S phase
G2 phase - ANSWER: G2 phase
At which point in the eukaryotic cell cycle does mitosis occur?
before the G1 phase
after the G2 phase
following the S phase
after the G0 phase - ANSWER: After the G2 Phase
An error occurs when the DNA of a cell is copied. However, the cell does not divide after the error is
detected. Which statement best describes the cell cycle for this cell?
An error during the G1 phase is corrected during the G2 phase.
An error during the S phase is corrected during the G2 phase.
An error during the G1 phase is corrected during the S phase.
An error during the S phase is corrected during mitosis. - ANSWER: An error during the S phase is
corrected during the G2 phase.
What is the purpose of the cell cycle?
DNA replication
development of positive mutations
prevention of cancer
growth, repair, and reproduction of cells - ANSWER: growth, repair, and reproduction of cells
Why is a skin graft necessary when cells are damaged by a third-degree burn?
to promote the repair of existing cells
to protect the area from infection
to prevent mutations
to replace damaged nerves - ANSWER: To protect the area from infection
Which is the main reason cells are replaced in the body?
The cells are too large.
The cells are inactive.
The cells are damaged.
The cells are cancerous. - ANSWER: The cells are damaged
Which can disrupt the cell cycle?
mutation
G0 phase
replication
cancer - ANSWER: Mutation
What is cancer?
addition of new cells to replace damaged cells
DNA replication
cellular death
uncontrolled cell division - ANSWER: Uncontrolled cell division
At which point in the eukaryotic cell cycle can a DNA mutation occur?
G1 phase
, G2 phase
S phase
M phase - ANSWER: S phase
Which best describes cancer cells?
Cancer cells cannot enter the circulatory system.
Cancer cells grow controllably.
Cancer cells attach to organs.
Cancer cells lose nutrients to healthy cells. - ANSWER: Cancer cells attach to organs
A mutation occurs that prevents a cell from taking in the glucose that it needs for energy production.
What is most likely to happen?
A tumor will form.
The cell will divide uncontrollably.
The cell will die.
Nutrients are stolen from normal cells nearby. - ANSWER: The cell will die
The graph shows the rate of malignant melanoma for the years 1973-2004.
Based on the information in the graph, which conclusion can be drawn?
More cases of cancer were reported over time.
More people were out in the sun over time.
Women use sunscreen about twice as often as men use sunscreen.
The rate of skin cancer has increased in both men and women. - ANSWER: The rate of skin cancer has
increased in both men and women
The graph shows the rates of malignant melanoma for the years 1973-2004.
Based on the information in the graph, what conclusions can be drawn about the rate of skin cancer
in men compared to that in women?
Skin cancer decreased at a faster rate in men than in women.
Skin cancer decreased at a faster rate in women than in men.
Skin cancer increased at a faster rate in men than in women.
Skin cancer increased at a faster rate in women than in men. - ANSWER: Skin cancer increased at a
faster rame in men than in women
The table shows the rate of melanoma by gender.

Consider the number of males who were diagnosed with melanoma in 2005. What quantity does this
number represent?
In 2005, 27.99 percent of males were diagnosed with melanoma.
In 2005, 27.99 males out of 100 were diagnosed with melanoma.
In 2005, 27.99 cases of melanoma were diagnosed in males.
