The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms.
The features of the nitrogen cycle are-
(i)Nitrogen fixation-Atmospheric nitrogen must be processed, to be used by plants.
(ii)Assimilation-Plants can absorb nitrate or ammonia from the soil via their root hairs. If nitrate is absorbed, it is first reduced to nitrite and then ammonia.
(iii)Ammonification-Bacteria, or fungi in some cases, convert the organic nitrogen into ammonium, a process called ammonification.
(iv)Nitrification-Conversion of ammonia to nitrate is performed primarily by soil-living bacteria and other nitrifying bacteria.
(v)Denitrification- Denitrification is the reduction of nitrates back into the largely inert nitrogen gas, completing the nitrogen cycle which is performed by Clostridium in anaerobic conditions.

Many invertebrates and a significantly smaller number of vertebrates are hermaphrodites. A hermaphrodite possesses both male and female reproductive organs during their life span. Some of these animals self-fertilize, while others require a partner. It is a condition which enables a form of sexual reproduction in which both partners can act as the "female" or "male". Examples: Snails,worms and about 21 families of fish are Hermaphrodites. Refer this link for more explanation:

A hysteroscopy is used to diagnose and treat problems of the uterus or womb. The procedure involves a thin, telescope-like camera inserted into the uterus via the ******. A diagnostic hysteroscopy is carried out to investigate abnormal uterine bleeding. Hysteroscopy can be carried out to aid in diagnosis or to perform minor surgical procedures. In many cases hysteroscopy can be performed as an outpatient (same-day) surgical procedure. Complications of hysteroscopy are rare. The most commonly reported complication is perforation of the uterus.

When the primordial follicle is stimulated, it becomes a primary follicle. The oocyte enlarges, and the follicular cells divide. A follicle that has two layers of follicular cells is called a primary follicle. These cells continue to hypertrophy and proliferate to form many layers surrounding the oocyte.
