Menstruation and Menstrual Cycle - At about the age of 10 to 13 years, the ovaries of females are stimulated by the follicle stimulating hormone (FSH) of the pituitary. This is called the onset of puberty and is accompanied by release of hormones oestrogen and progesterone. Thes..

Hormonal Control of Cyclic Changes in Ovaries and Uterus During Menstrual Cycle - The cyclic changes in the ovary and uterus are under the control of estrogen and progesterone hormones whose secretion is under the control of gonadotropic hormones secreted by anterior pituitar..

In women, reproductive phase begins with the onset of menses at about the age of 13 years. It ends with its cessation (menopause) at about the age of 45 - 49 years. During this reproductive period, the ovaries and the female reproductive tract undergo a series of cyclic changes which are prim..

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..

1) During this pathway many intermediate compounds are formed, which are used in the synthesis of other biomolecules like amino acids, nucleotides, chlorophyll, cytochromes and fats. For example, succinyl COA is the starting molecule for synthesis of chlorophyll. 2) This is the major pathway for g..

Born Haber Cycle - Based on Hess's law Born and Haber in 1919 developed a simplified and cyclic method to correlate lattice energies of ionic crystals to other thermodynamic data. For example, the net energy changes during the formation of sodium chloride from metallic..

When all the hydrogen gets exhausted, fusion stops and as a result the internal pressure, which keeps the star from collapsing under its high gravitational force decreases and the core contracts under its own gravity. However, the hydrogen in the outer shell fuses to helium and releases energ..
