None of the above

Cancer is the uncontrolled growth and division of cell.

TRUE

FALSE

10.

Cancer creates abnormal cells by disrupting

the cell cycle

red blood cell formation

DNA replication

ATP synthesis

11.

An abnormal mass of cancer cells is called a

tumor

cyst

lesion

polyp

12.

Metastasis is

the spread of cancer from one part of the body to another.

the growth of tumors in the lungs

cancer of the blood cells

cancer that is found in connective tissues

13.

Cancer cells can multiply in which situations?

Presence of growth factors

Absence of growth factors

Signals that prevent cell division

None of the above

14.

Cancer may emerge when both of the tumor-suppressor genes are _____

activated

inactivated

enhanced

15.

Stem cells are

cells that grow uncontrollably

undifferentiated and can be any type of cell

never go through cell division

only found in embryos

16.

What does "pluripotent" mean?

able to divide and make many different types of cells

not able to divide

can only divide and make one cell type

if it divides, it will make a cancerous tumor

genetic engineering

survival of the fittest

differentiation

selective breeding
