Answer:
↓
Explanation:
I can't really read what you have typed, but the subscripts are the little numbers such as this 2 in H₂O. So using the blue pen, I'm assuming you would circle the little numbers. The coefficients are the numbers in front of the elements so from what I can read, in 2HCl the 2 would be circled in the orange. So in a simple way the subscripts are the tiny numbers that are at the bottom (usually after elements), and the coefficients are normal numbers in front of the whole element.
Hopefully that makes sense! :)
B, is the answer. I believe.
*High ventilation/low perfusion that Increased the cardiac output Decreased of the pulmonary vascular and the resistance and *Pulmonary hypertension,*Reduced the left ventricular preload
Pulmonary hypertension is happens when the pressure in the blood vessels and leading from the heart and the lungs is too high. With the pulmonary hypertension, the blood vessels in the lungs to develop the increased amount of muscle in wall of the blood vessels
It's a serious condition which can be damage the right side of the heart. and The walls of the pulmonary and the arteries to become the thick and the stiff, and that cannot be expand as well they allow blood through.
