Answer to Question 1

ANS: A
Unlike those of other muscle tissues, however, cardiac contractions cannot be sustained or teta-nized because myocardial tissue exhibits a prolonged period of inexcitability after contraction. The period during which the myocardium cannot be stimulated is called the refractory period.

Answer to Question 2

ANS: A
Inherent rhythmicity or automaticity is the unique ability of the cardiac muscle to initiate a spon-taneous electrical impulse.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
