Following are the characteristics of the electrolysis process: 1) Electrolytic reactions involve the gain of electrons at the cathode and loss of electrons at anode. 2) The cathode reaction is a reduction reaction as the cations accept electrons, while the anode reaction is an oxidation reaction..

'The rate of organic matter build up or stored by producers in their bodies per unit time and area is called net primary production (NPP)'. \ GPP - Energy lost by respiration and maintenance = NPP The biochemical formula that describes photosynthesis is,..

Gonads are the reproductive organs. The male gonads are the testes and the female gonads are the ovaries. Both produce hormones under the influence of hormones of the pituitary (see under pituitary gland). Testes produce testosterone which produces the secondary sexual characteristics lik..

An alkyl halides or a benzyl halide reacts with ammonia to form primary secondary and tertiary amines. If ammonia is used in excess primary amine is the major product. Under these conditions in the reaction mixture, an alkyl halide is more likely to encounter and react wit..

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. These hormones control the production of ova or ..

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. These hormones control t..

From Alkyl halides - Alkyl halides on treatment with ethanolic solution of sodium cyanide or potassium cyanide give alkyl cyanide..

When the key K is pressed, current starts flowing through the coil P and this increases the magnetic flux linked with P. Since S is very close to P, the magnetic flux linked with S also increases. Thus induced emf, hence induced current is produced in S. The direction of induced current in S is gi..
