Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): | In nearly all animal tissues specialized junction provide both structural and functional links between its individual cells. |
Reason (R): | Cell junctions always help to stop substances from leaking across a tissue |
1. | (A) is True but (R) is False. |
2. | (A) is False but (R) is True. |
3. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
4. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
1. | Bone – ostocytes embedded in hydroxyapatite in osteon |
2. | loose connective tissue – collagenous, elastic, reticular fibers |
3. | adipose tissue – loose connective tissue with fat storing cells. |
4. | Fibrous connective tissue – chondrichthyes embedded in chondroitin sulfate. |
Assertion (A): | Haversian canal is the characteristic of Mammalian long bone. |
Reason (R): | Spongy bone of Mammal is highly vascular, and it is the place for the formation of red bone marrow |
