Answer to Question 1

A
On the ECG, the P wave represents atrial depolarization and the QRS complex represents ventricular depolarization.

Answer to Question 2

C
The movement of charged particles across a cell membrane causing the inside of the cell to become positive is called depolarization. Depolarization must take place before the heart can mechanically contract and pump blood.
