Answer to Question 1

ANS: A
Anaphase begins when the centromeres split and the sister chromatids are pulled apart. During telophase, a new nuclear membrane is formed around each group of 46 chromosomes, the spindle fibers disappear, and the chromosomes begin to uncoil. During prophase, the first appearance of chromosomes occurs. Metaphase occurs when two centrioles located at opposite poles of the cell pull the chromosomes to opposite sides of the cell.

Answer to Question 2

ANS: C
Different types of cells require different growth factors; for example, PDGF stimulates the pro-duction of connective tissue cells, but not platelets, epidermal cells, or fibroblast cells.
