(a)
Interpretation: The given statement that bioorganic substances are slightly more abundant than bioinorganic substances concerning human body composition, in terms of mass percent has to be validated.
Concept introduction: The chemical substance found in the living organism is called biochemical substance. The biochemical substance is further subdivided into bioinorganic substance and bioorganic substance. Bioinorganic substances do not contain carbon, for example water and inorganic salts. On the other hand bioorganic substances contain carbon, for example lipids and carbohydrates.
(a)

Answer to Problem 7.1EP
The statement, bioorganic substances are slightly more abundant than bioinorganic substances concerning human body composition, in terms of mass percent is false.
Explanation of Solution
It is usually misconcepted that the human body contains a major part of the organic substances. The human body has only one-fourth by mass of the organic substances i.e. the carbon contatining substances like the lipids, carbohydrates,
Therefore, bioorganic substances are not slightly more abundant than bioinorganic substances.

Answer to Problem 7.1EP
The statement, bioinorganic substances are much more abundant than bioorganic substances concerning human body composition, in terms of mass percent is true.
Explanation of Solution
It is usually misconcepted that the human body contains a major part of the organic substances. The human body only has one-fourth by mass of the organic substances i.e. the carbon contatining substances like the lipids, carbohydrates, nucleic acids while the human body has 70 % of the water, i.e two-third by mass of the body consists of inorganic substances.
Therefore, bioinorganic substances are much more abundant than bioorganic substances.
