Explanation / Answer
1. ADH has 9 amino acids
2. P wave represents the atrial depolarization [The first even in the cardiac cycle is atrial depolarization. The first positive wave in the EKG is P, so P is the wave which represents the atrial depolarization.]
3. T wave represents the ventricular repolarization. [ this is the last event of a cardiac cycle, t wave is the last wave of EKG]
