Question

the diagram shows the division of a stem cell to form muscle cells and nerve cells. what causes the stem cell to differentiate into one or more types of specialized cells? mutation of stem cell genes at the time of cell division difference in the rate of mitotic division in the two cells expression of different genes by both cell types inheritance of different types of dna by both the cells

Explanation:

Stem - cell differentiation occurs due to differential gene expression. All cells have the same DNA, but which genes are turned on or off determines cell type. Mutations are not the main cause of normal differentiation, mitotic rate doesn't determine cell - type, and cells inherit the same DNA.

Answer:

C. expression of different genes by both cell types
