B)Ability to undergo apoptosis on schedule
C)Tight regulation of cell division
D)Conservation of energy

Question

Quizplus · Accepted Answer

Although the gene for insulin is present in all body cells, it is only expressed in the beta cells of the pancreas. Thus, the gene product insulin is an example of a specific differentiated function performed by one cell type. Energy is used by the beta cells in the performance of this differentiated function. The process does not represent either regulation of cell division or the capability of apoptosis.
