During which phase of the cell cycle does cell division occur?

• G1 Phase

• M Phase

• S Phase

• G2 Phase

What is the importance of the S Phase?

• The cell grows larger. 

• Organelles are duplicated.

• DNA is replicated.

• The cell divides into two daughter cells.

Stem cells are

• cells that grow uncontrollably

• undifferentiated and can be any type of cell

• never go through cell division

• only found in embryos

What process best explains how muscle cells and nerve cells can develop from the same fertilized egg?

• genetic engineering

• survival of the fittest

• differentiation

• selective breeding

Which best explains why muscle cells are different from blood cells?

• Muscle cells are produced by the brain, but blood cells are produced by the heart. 

• Different genes are activated in muscle cells than in blood cells. 

• Muscles cells experience different environmental influences than blood cells. 

• A mutation occurs during the development of muscle cells but not in blood cells.
