Question

Assertion (A): In large animals, oxygen can reach different parts of the animal’s body easily.

Reason (R): Respiratory pigments take up oxygen from the air and carry it to body tissues.

Options

• Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).

• Both Assertion (A) and Reason (R) are true, and Reason (R) is not the correct explanation of Assertion (A).

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).

Explanation:

Respiratory pigments like hemoglobin, which bind to oxygen and carry it throughout the body, are part of the circulatory systems of large animals. This ensures that oxygen reaches all parts of the body.
