Organic chemistry is that branch of chemistry which deals with the study of compounds of carbon with hydrogen (hydrocarbons), and their derivatives. Presently about five million organic compounds are know..

Summary - While the nervous system and endocrine system have their own features, they have a common method of communication. Both the systems release chemicals to communicate between cells. Together these two systems carry out a very complex process of maintaining a homeostatic ..

Previously, we were adding sine waves of exactly the same frequency. Now, we shall add sine waves of different frequencies, but close to each other. In this case, as time goes on, the sine waves would get increasingly out of phase with each other. The simplest case would be the sum of two equal sin..

During a redox reaction, the total increase in oxidation number must be equal to total decrease in oxidation number. This is the basic principle for balancing chemical equations. In addition, the number of atoms of each kind on one side of the equation must be equal to the numb..

Mendelian Genetics - The biggest name in the entire history of genetics beyond any doubt is that of Gregor Johann Mendel (1822-1884). It was Mendel, more than any other scientist, who synthesized the basic principles of heredity into a body of knowledge that has formed the very ..

When the amplitude of high frequency carrier wave is changed in accordance with the intensity of the signal, it is called amplitude modulation. In amplitude modulation, only the amplitude of the carrier wave is changed in accordance with the intensity of the signal. However, the frequency of the mo..

In this, the cancerous parts of the body are exposed to ionising radiations like x-rays, which kill the cancerous cells. It gives good results in skin, lip, mouth and cervix cancers. Radiation therapy is used in 80% of cancer patients. The basic principle here is to bombard the..
