Why are immortal cell lines important for biological research?

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

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 types of tissues that can be grown in culture.
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 amount of time a tissue can be kept alive in culture.
D
A lack of blood flow determines the number of cell layers that can survive when they are transplanted.
