Muscle tissue and bone tissue contain cells that

select one:
a. use one part of the genetic code to make proteins needed by the cell.
b. contain different numbers of dna molecules.
c. have the same genetic information but perform different specialized functions.
d. produce hormones that make the cell stronger.

The correct answer is c.
All the cells of a person's body share the same genetic information. Although muscle and bone tissue have different functions, their cells have exactly the same set of genes. The difference is that every type of tissue has specialized cells which different structure and function. This cell differentiation is achieved through cell-specific gene expression, meaning that each cell can turn on or off specific genes, in accordance with its needs. 

The correct answer is b
