Question

Which of the following statements about biomolecules is true?

I. Biomolecules are the basis of life.
II. Biomolecules are involved in the metabolic processes of all living organisms.
III. Biomolecules are inorganic molecules.​

Answer 1

Step-by-step explanation:

The following statement about biomolecules is true:

II. Biomolecules are involved in the metabolic processes of all living organisms.

Step-by-step explanation:

I. Biomolecules are indeed essential components of life, but they are not the sole basis of life. Life also depends on various physical and environmental factors.

III. Biomolecules are organic molecules, primarily composed of carbon, hydrogen, oxygen, nitrogen, and sometimes other elements. They are not inorganic molecules.

So, statement II is the correct one as biomolecules play a crucial role in the metabolic processes of all living organisms.

Answer 2

Statements I and II are true, but statement III is false.

Step-by-step explanation:

• Statement I is true. Biomolecules are the organic molecules that make up living organisms. They are essential for all life processes, including growth, reproduction, and metabolism.
• Statement II is true. Biomolecules are involved in all metabolic processes, which are the chemical reactions that occur in living organisms to keep them alive.
• Statement III is false. Biomolecules are organic molecules, which means that they contain carbon. Inorganic molecules do not contain carbon.

Therefore, the correct answer is I and II only.
