Why will life processes be affected if wastes keep accumulating in the body?
Answer and explanation
Correct answer: Because wastes can disturb normal cell functions
The governing concept is excretion and internal balance, or homeostasis. Metabolic reactions produce wastes such as carbon dioxide, urea and excess salts. If these substances accumulate, they can alter pH and water balance, damage cells, and interfere with enzyme activity and organ function. Consequently, essential life processes are disturbed. Option A is correct; the other options incorrectly describe wastes as useful food, oxygen or plant regulators.
