	7.35-7.45.......acidosis
	7...alkalosis
	7.35-7.45...alkalosis
	7....acidosis

Solution

1. The pH of blood (7.35-7.45) is maintained by physiological buffers in the form of bicarbonates, proteins etc. When pH falls below normal, it means more acidic (Acidosis), while as when pH goes above normal value, the blood becomes alkaline (Alkalosis).

Therefore, the correct answer is:7.35-7.45...alkalosis
