The answer is B: there would be fewer American Indians or B: Slavery would not have been permitted
Answer:
The correct answer will be option B.
Explanation:
Blood pressure represents the pressure of the blood in the major arteries of the body.
This blood pressure increases in the arteries when the ventricle contracts to push the blood to the major artery by a mechanism called ventricular systole. This increased blood pressure number is known as systolic blood pressure which is usually 180 mm of Hg.
The blood pressure decrease in the artery due to ventricular diastole during which ventricles relaxes. This lower number of blood pressure is known as diastolic blood pressure which is 80 mm of Hg.
Thus, option B is the correct answer.
