(a)
Interpretation: Between water and proteins, the member which is more abundant, on a mass basis, in the human body has to be predicted.
Concept introduction: Those substances that do not contain carbon are known as bioinorganic substances and those substances that contain carbon are called bioorganic substances. In terms of mass composition for human body, bioinorganic substances are much more abundant than bioorganic substances.
(b)
Interpretation: Between carbohydrates and lipids, the member which is more abundant, on a mass basis, in the human body has to be predicted.
