It lasts for about 3 - 5 days and extends from the 1 s t - 4 t h day of the menstrual cycle. When fertilisation of ovum does not take place, the corpus luteum starts degenerating. The level of progesterone in the blood starts decreasing. The uterine tissues fail to be maintained..

Water is an indispensable commodity of life. Water determines the distribution, structure and function of organisms in the ecosystem. Water occurs in three phases - solid, liquid (ice/snow) and gaseous (water vapour). In liquid phase it is vital for the existence of life on this planet. In gaseous ..

Kreb's Cycle - The oxidation of pyruvic acid into CO 2 and water is called Krebs cycle. This cycle is also citric acid cycle because the cycle begins with the formation of citric acid. Citric acid is a carboxylic acid containing 3 COOH groups. Hence..

Cell Cycle - Every cell that is capable of undergoing division passes through a cyclic sequence of events involving growth and division. It is called Cell Cycle. It encompasses the entire sequence of events that occur in a cell from the time it is formed from its parent cell til..
