Answer:
The correct answer will be option-A
Explanation:
Electrocardiogram or ECG is the recording and representation of the electrical changes that are taking place during the cardiac cycle.
The QRS complex is preceded by the P wave or atrial systole or atrial depolarization after which the electrical signals are passed on to the AV node.
As soon as the AV node passes the electrical signals to bundle of His, it is observed in as the QRS interval which represents the atrial diastole and the onset of ventricular depolarization.
Thus, option-true is the correct answer.

Answer:
d. cell membranes
Explanation:
The movement of the the fluid is a combination of both the osmotic and the hydrostatic pressures.
Osmotic pressure results from the differences in the solute concentrations across the cell membranes. On the other hand, hydrostatic pressure results from pressure of the blood as it enters the capillary system, forcing some amount of the fluid out of vessel into surrounding tissues.
<u>As a result of these factors, the fluid movement occurs through cell membrane.</u>
