Notes:
Cloves are native to the Maluku Islands (or Moluccas) in Indonesia. They are the aromatic flower buds of a tree in the family Myrtaceae, Syzygium aromaticum. They are generally used as a spice.

Notes:
Bile is secreted by Hepatocytes. It is a complex aqueous secretion that originates from hepatocytes. It is modified distally by absorptive and secretory transport systems in the bile duct epithelium.

Notes:
Myosins refers to a superfamily of motor proteins known for their roles in muscle contraction and other motility processes in eukaryotes. These proteins are basically specialized motor machines that convert the cellular free energy to mechanical work. They depend on ATPs for actin based motility.

Notes:
Archosaurs (crocodilians and birds) and mammals show complete separation of the heart into two pumps, for a total of four heart chambers;

Notes:
The Bovine spongiform encephalopathy (BSE) is commonly known as Mad Cow Disease. It is a brain disorder in an adult cattle that may be spread to humans through diseased meat.

Notes:
Bombay Blood Group is an extremely rare ABO group, called so because it was first discovered among some people in Bombay. Their red cells lack ABH antigens and their sera contain anti-A and anti-B and anti-H. The anti-H would not be detected in the ABO group but would be detectable in pretransfusion tests. People who have Bombay phenotype can donate to any member of the ABO blood group system (unless some other blood factor gene, such as Rhesus, is incompatible), but they cannot receive any member of the ABO blood group system`s blood (which always contains one or more of A and B and H antigens), but only from other people who have Bombay phenotype

Notes:
The Coral Reef ecosystem showcases the highest biodiversity among the options provided. This is due to the ideal tropical environment in which they exist, offering a wide range of habitats, shelter, and nourishment for an astonishing array of marine life. In terms of biodiversity, they are second only to tropical rainforests. Interestingly, despite covering less than 1% of the ocean floor, coral reefs support about 25% of all known marine species.

Notes:
Potato and Brinjal have several common features and are thus included in the same genus Solanum. The scientific name of Potato is Solanum tuberosum and Brinjal is Solanum melongena.

Notes:
Cereals which are made with puffed or powdered rice and refined wheat typically contain starch. Starch is the most common form of carbohydrate and typically found in staple grains like rice, wheat, and corn.
