Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Fats serve as an insulator in the body.
Reason (R): It helps to prevent the rapid change in temperature and cushions organs from sudden injury.
In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is false but (R) is true.
• D. (A) is true but (R) is false.

Hint:

The physiological functions of adipose tissue include both thermal insulation (protecting against heat loss) and mechanical cushioning (protecting against physical shock).

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Adipose tissue (body fat) serves multiple vital structural and physiological roles in the human body beyond simple energy storage.

Step 2: Detailed Explanation:
- Assertion (A): Subcutaneous fat acts as an effective thermal insulator in the body. (Assertion A is correct)
- Reason (R): Fat is a poor conductor of heat, meaning it reduces heat loss through the skin, helping the body maintain a stable core temperature despite external changes. Additionally, visceral fat deposits around internal organs act as mechanical cushions, absorbing shock and protecting them from physical trauma. (Reason R is correct and directly explains why and how fat acts as an insulator/protector)

Step 3: Final Answer:
Both (A) and (R) are true, and (R) is the correct explanation of (A), representing Option A.
