The production of which substance by using cell technology allows scientists to make treatments that can target specific types of cancer cells?

A
fat-soluble vitamins
B
steroid hormones
C
monoclonal antibodies
D
complex proteins
3

Which advance in biology resulted from developments in cell technology?

A
tissue typing
B
aseptic technique
C
immortal cell lines
D
somatic cells
4

Which issue is a negative effect of cell technology on society?

A
Organ culture increases the time between donation and transplant.
B
Immortal animal cell lines can be used to model human cells.
C
The use of human cells in research can lead to ethical problems.
D
People are more aware of the results of cell technology research.
5

Why are immortal cell lines important for biological research?

A
They have two nuclei, allowing them to divide faster than normal cells.
B
They grow spontaneously rather than going through the process of mitosis.
C
They can replicate indefinitely and do not experience natural cell death.
D
They grow larger than normal cells so that they can divide into multiple cells.
6

Why is it important for scientists to develop a way to grow tissues that have a built-in system to supply blood?

A
A lack of blood flow determines the number of cell layers that can survive when they are transplanted.
B
A lack of blood flow determines the amount of culture medium that is needed to keep a tissue alive.
C
A lack of blood flow determines the types of tissues that can be grown in culture.
D
A lack of blood flow determines the amount of time a tissue can be kept alive in culture.
7

Why is the ability to culture stem cells important?

A
Stem cells are easier to culture than other types of cells.
B
Stem cells make reproductive cloning unnecessary.
C
Stem cells are easier to immortalize than cancer cells.
D
Stem cells can be stimulated to develop into any cell type.
8

How did the development of the HeLa cell line affect society?

A
It caused the contamination and destruction of other immortal cell lines.
B
It prevented the collection of other human cell types for research.
C
It resulted in patient consent being required for tissues to be used in research.
D
It led to the production of the most widely studied mortal cell line in the world.
9

What is an advantage of using cell culture rather than bacterial culture to produce biological molecules?

A
Cell culture can be used to produce complex proteins.
B
Cell culture can be used to produce clones.
C
Cell culture can be used to produce steroid hormones.
D
Cell culture can be used to produce fat-soluble vitamins.
10

What is a stem cell?

A
a mature egg cell that is capable of forming a new organism
B
a specialized cell in the skin that identifies pathogenic organisms
C
a cell from which a new cell that has a specialized function is formed
D
a cell that has half the number of chromosomes of a parent cell
