Question

what is the rate and extent of a nutrients absorption and use?
o a. activity quotient
o b. bioactivity
o c. bioavailability
o d. availability ratio

Explanation:

To solve this, we analyze each option:

• Option a: Activity quotient is not related to nutrient absorption/use.
• Option b: Bioactivity refers to a substance's effect on a biological system, not absorption/use rate/extent.
• Option c: Bioavailability is defined as the rate and extent of a nutrient (or substance)’s absorption and use, which matches the question.
• Option d: Availability ratio is not a term for nutrient absorption/use.

Answer:

c. Bioavailability
