Answer to Question 1

ANS: C
Colony stimulating factors need only be present in a very low concentration to be effective. They have a high affinity for their target cells, binding to specific receptors on the cell surface. Many different cells produce them, and many of them affect several different cell lines.

Answer to Question 2

ANS: A
Germinal centers contain primarily B cells and their progeny.
