In plants, algae, and cyanobacteria, photosynthesis uses carbon dioxide and water, releasing oxygen as a waste product. Photosynthesis is vital for all aerobic life on Earth. In oxygenic photosynthesis water is the electron donor and, since its hydrolysis releases oxygen, the equation for this process is: Carbon dioxide + Water + Light energy → Carbohydrate + Oxygen + Water

Correct Option: B

Xylem is of a plant's vascular system that conveys water and dissolved minerals from the roots to the rest of the plant and furnishes mechanical support. It constitutes the major part of a mature woody stem or root and the wood of a tree, and consists of specialized water-conducting tissues made up mostly of several types of narrow, elongate, hollow cells.

Red blood cells, or erythrocytes, are the most common type of blood cell and the vertebrate organism's principal means of delivering oxygen (O₂) to the body tissues via the blood flow through the circulatory system. The cytoplasm of these cells is rich in haemoglobin, an iron-containing bio-molecule that can bind oxygen and is responsible for the blood's red colour.

Iodine exists in soil, but the content may vary because soil erosion can leach away this and other minerals. Beans and seeds highest in iodine content include lima beans, soybeans, cooked navy beans and sesame seeds. Vegetables highest in iodine include spinach, Swiss chard, turnip greens, summer squash and white potatoes with the peel. The herb highest in iodine is garlic.

Rabies is a viral disease that causes acute encephalitis in warm-blooded animals. The disease is zoonotic, meaning it can be transmitted from one species to another, such as from dogs to humans, commonly by a bite from an infected animal.
