Account for the following :
(i)Aspirin drug helps in the prevention of heart attack.
(ii)Diabetic patients are advised to take artificial sweeteners instead of natural sweetners.
(iii)Detergents are non-biodegradable while soaps are biodegradable.

Explanation

(i)Most of the heart attacks are due to blood clotting in the coronary arteries. Aspirin helps to make the blood thinner and thus prevents the formation of blood clots in the coronary arteries thereby preventing heart attacks.
(ii)Diabetic patients do not produce enough insulin to metabolize the natural sugar. As a result, sugar remains in the blood and thus affects, liver, heart and kidneys. Therefore, diabetic patients are advised to take artificial sweeteners such as saccharin. It is not metabolized in the body and is excreted as such through urine without affecting the heart, liver and kidneys.
(c )Soaps have straight hydrocarbon chains which are easily degraded by bacteria present in the sewage water and hence do not cause water pollution, aspartame. Most of the detergents, on the other hand, have branched hydrocarbon chains which are either not attacked or attacked only slowly by bacteria. As a result, detergents remain undegraded in rivers and waterways and thus cause water pollution.
