The process by which plants produce offspring from vegetative parts is: MCQ with Answer and Explanation

Explanation:
Vitamin E (tocopherol) is a lipid-soluble antioxidant that scavenges free radicals and prevents lipid peroxidation of cell membranes. Vitamin C is water-soluble antioxidant, A is for vision, K for clotting.

Explanation:
Vitamin A is essential for the formation of rhodopsin in the retina; its deficiency causes night blindness. Vitamin B1 (thiamine) deficiency leads to beriberi, characterized by nerve and heart issues. Vitamin K, not Vitamin C, is essential for the synthesis of blood clotting factors like prothrombin. Vitamin C is essential for collagen synthesis and immunity. Thus, statements 1 and 2 are correct.

Explanation:
The Haversian canal (central canal) is the core of the osteon (Haversian system) in compact bone. It runs parallel to the long axis of the bone and contains the blood vessels (arterioles, venules, capillaries), nerve fibers, and lymphatic vessels that supply the bone tissue. The concentric lamellae surround this canal. Osteocytes are housed in lacunae between the lamellae, and red bone marrow is found in the medullary cavity of long bones or the spaces of spongy bone.
