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.

struggling to breathe -- gasping -
Answer:
1 When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photo receptors turn the light into electrical signals.
These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.Focal vision is involved in examining and recognizing objects related with the macular area of the retina whereas peripheral vision is vision resulting in stimulation of the retina outside the macula. An example of peripheral vision would be looking straight ahead while also being able to see on the side by the eye.
Explanation:
2The pituitary gland is enveloped by dura and sits within the sella turcica of the sphenoid bone. The sella turcica is a saddle-shaped depression that surrounds the inferior, anterior, and posterior aspects of the pituitary.When a pituitary tumor pushes the optic chiasm, it causes visual loss in both eyes. In addition to the optic nerve, which brings vision from the eye to the brain, there are also several other nerves near the pituitary gland that travel to the eyes and help them move normally.
