The purpose of hydrogenating unsaturated fats is to make them more solid at room temperature as it is easy store the product.

Deficiency of Iodine cause Goiter also called Enlarged Thyroid. It doesn't give any pain but difficult to swallow and breath are its causes.

Meiosis takes in the capsule of the Bryophytes.

Bile contains bile acids, which are critical for digestion and absorption of fats in the small intestine. Since bile increases the absorption of fats, it is an important part of the absorption of the fat-soluble substances, such as the vitamins A, D, E, and K. Besides its digestive function, many waste products, including bilirubin, a byproduct of red blood cells recycled by the liver are eliminated from the body by secretion into bile and elimination in feces.

Testosterone is the hormone which is associated with aggression.

Ribosomes comprise a complex macro molecular machine, found within all living cells, that serves as the site of biological protein synthesis. Ribosomes link amino acids together in the order specified by messenger RNA molecules.

Increasing the Alveolar ventilation rate will increase the rate of carbon dioxide diffusion from the blood to the alveoli.

Fermentation is the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.

The two most common types of fermentation are

(1) alcoholic fermentation (and) 

(2) lactic acid fermentation.

(1) Alcoholic fermentation : the type of fermentation in which ethyl alcohol is the main end product .This is very common in yeast (unicellular fungus) and also seen in some bacteria. Yeast cells release enzymes called zymase complex which bring about the fermentation. The reactions are similar to anaerobic respiration.

(2) Lactic acid fermentation : The type of fermentation in which lactic acid is the end product.

It is carried out by some bacteria (e.g. lactic acid bacteria), and also by animals (muscle glycolysis in animals, under oxygen deficiency, results in the formation of lactic acid this is whay we experience in muscle cramps, or "Charley horse").
