differentiate into more types of cells
live longer
differentiate into only 2 types of cells

Which of the following would be an example of cell differentiation?
Cardiac cells helping the heart beat
skin cells replicating to repair a wound
nerve cells transmitting messages
all of these are examples of cell differentiation
Skin cells and red blood cells are different in structure and function because of:

to mix solutions
to transport molecules through the membrane
A freshwater plant is put in a saltwater tank. What would happen to the plant cells?

the cells would swell up and burst
nothing would happen to the cells
What is homeostasis?
a solution that neutralizes acids
another word for passive transport
making peace with outside environments
the regulation of an organism and/or cell's internal conditions, which requires responding to needs and/or changes in the environment
What is happening to the cell during the S phase of Interphase?
the cell explodes
the DNA replicates
chromatids separate
The homologous chromosomes cross over
The offspring of an asexual organism are:
genetically different from the parent
genetically identical to the parent
there is no such thing as an asexual organism
they are produced from gametes
What is the result of a single cell that reproduces by mitosis?

2 cells with identical genetic material to the parent cell
2 cells with half of the genetic material of the parent cell
4 cells with half the genetic material of the parent cell

addition
The Brac Gene can cause breast and ovarian cancer. Studies show that this gene is genetic and can be passed on to offspring. What does this mean?
it means nothing
the mutation is in somatic cells
your offspring give you the gene
the mutation is in gametes
