Answer to Question 1

ANS: C
Excitability is defined as the ability of a cell to respond to an electrical stimulus. Conductivity re-fers to the ability of cardiac tissue to propagate an action potential. Automaticity describes the ability of certain specialized cells of the heart to depolarize. Rhythmicity refers to the heart's pacemaker action potential.

Answer to Question 2

ANS: C
Conductivity is defined as the ability of cardiac tissue to propagate an action potential. Excitabil-ity refers to the ability of a cell to respond to an electrical stimulus. Automaticity describes the ability of certain specialized cells of the heart to depolarize. Polarization occurs when a cell be-comes electrically activated.
