. The excited atoms return to the lower state L from higher state H in two steps. First they return to metastable state M. This transition is non-radioactive and energy of this transition is passed to the crystal lattice as heat. The chromium atoms that returned to M level can remain in this state ..

A single enzyme that synthesizes RNA from DNA is RNA polymerase. The transcription starts when the enzyme gets binded to DNA at a region known as promoter region. The binded RNA polymerase recognizes two base sequences on non-coding strand of DNA to start the transcri..

Growth is stunted, appetite is poor Stomach gets distended The eyes are bulging The patient develops match stick legs- legs become thin, long and curved Skin may become dark and start peeling off and hair may become dull and loose its lusture..

When a chemical reaction gets started the reactants are present in the initial stage, but as the reaction proceeds, the concentration of the reactants decreases and that of products increases. Finally, a stage is reached when no further change in concentration of reactants and p..

Write for five minutes as fast as you can, but this time stick to one subject may be the given subject -say sports. Do not worry about spelling, punctuation or even complete sentences. Do not change the topic. It will let you see what material you have and will help you figure out what aspect of ..

Introduction - When a chemical reaction gets started the reactants are present in the initial stage, but as the reaction proceeds, the concentration of the reactants decreases and that of products increases. Finally, a stage is reached when no further change in concentration of ..

Phenyl Ketonuria (PKU) is a common metabolic disorder in growing children. A child suffering from PKU has defective legs and is usually unable to stand. Such a child may also be mentally retarded. This condition is due to a defect in the amino acid metabolism. In the course of amino acid metabolis..

At a given volume, the pressure of a given mass of a gas is proportional to its absolute temperature. This is Charle's law for pressure. This is the definition of the absolute temperature, T. If one starts from the fact that T and uses the fact that V is constant, one gets..

) where the third shell is partially complete (3s 2 3p 6 ). The fourth period corresponding to 'n' = 4, consists of filling of one '4s' and three '4p' orbitals. The '4d' and '4f' orbital are higher in energy than the '5s' orbitals and are filled later. The five '3d' orbitals have energies in betwee..
