Hence, the total number of elements = 12 (= total values of spin quantum number)

Marasmus is a disorder caused by a deficiency of food or protein. Marasmus occurs in infants below 1 year of age when they do not get sufficient mother's milk or weaning diet. Such infants are often provided with very diluted cow or buffalo milk. Marasmus babies have emaciated bodies with shriveled appearance, thin face, sunken eyes, wrinkled thin and dry skin, protruding ribs, reduced digestion, and frequent diarrhea.

Epoxypropane reacts with CH₃MgBr to give butan-2-ol as follows:

C₄ plants are special: They have a special type of leaf anatomy, they tolerate higher temperatures, they show a response to high light intensities, they lack a process called photorespiration and have greater productivity of biomass. Photorespiration is absent is C₄ plants. Photorespiration does not produce energy or reducing power. Rather, it consumes energy. Further, it undoes the work of photosynthesis. There is 25% loss of fixed CO₂. Therefore, photorespiration is a highly wasteful process. This happens only in the case of C₃ plants.

In creatures where the egg and sperm are combined inside the mother's body or by interbreeding, those beings have a secretion of some type of fluid from the male's special glands, which is called semen. Sperm are mixed with this fluid. The sperm swim through the semen, through the antrum, enter the fallopian tube and connect with the egg. The antrum is the fluid-filled space found in antral or Graafian follicles; also called the follicular cavity.

Fungi belong to their kingdom of eukaryotic organisms classified in the eukaryote domain. Plants, animals, algae, and fungi all are eukaryotes because they don't have chlorophyll and vascular tissue and line by decomposing and absorbing organic matter from living or dead sources. Fungi are heterotrophic because they cannot produce their food, fungi can be single-celled or very complex multicellular organisms. The cell wall of fungi is mainly composed of Chitin.

Castle Intrinsic factor (IF), also known as a gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells of the stomach. It is necessary for the absorption of vitamin B₁₂ later on in the ileum of the small intestine. Cyanocobalamin is a man-made form of vitamin B₁₂ Vitamin B₁₂ is important for growth, cell reproduction, blood formation, and protein and tissue synthesis. Cyanocobalamin is used to treat vitamin B₁₂ deficiency in people with pernicious anaemia and other conditions.

It was 7 lakh years ago when herbs and grasses increased in population. They belonged to the epoch Pleistocene of the Quaternary period. They collectively occurred during the Cenozoic era.

The latest major group of plants to evolve were the grasses, which became important in the mid-Paleogene, from around 40 million years ago. The grasses, as well as many other groups, evolved new mechanisms of metabolism to survive the low CO₂ and warm, dry conditions of the tropics over the last 10 million years.
