electronic components

Three different companies produce a particular type of electronic component. Random samples of components are selected from each company. Components are put into actual use until they fail and the life time of the components noted are as shown. At &..

Electron Transport System - Electron transport chain refers to the light driven reactions of photosynthesis. They were first formulated in 1939 by Robert Hill. The two photosystems are connected in series with each other by the components of electron transpor..

Electron Transport System - The metabolic pathway through which the electron passes from one carrier to another, is called the electron transport system. Electron Transport System (ETS) in Mitochondrion The electron transport system occurs in the in..

It is used for medical diagnosis and therapy and also as a surgical tool. Bats and porpoises use ultrasound for navigation and to locate food in darkness. It is used to detect defective foetus. It is used as a tool in the treatment of muscular pain. Ultra sonography (is a technique of..

The nuclei of atoms is made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the number of protons in the nucleus is exactly equal to the number..

Atomic Number, Mass Number or Nucleon Number - The nuclei of atoms are made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the number of proto..

The use of chlorofluorocarbons gases (CFC) is posing a grave threat to the existence of ozone in the stratosphere. CFCs have a wide range of applications due to their properties like non-corrosiveness, non-inflammability, low toxicity and high chemical stability. They are used as refrigerants, pro..

If the electronic compounds like resistors, capacitors, diodes and transistors are compactly put in a small piece of material, it is called as integrated circuit. This single small package performs a complete electronic function. Thin slice of crystal of silicon of the orde..

>Peptiglycons are found in the cell walls of prokaryotic cells. Proteins are polymers of aminoacids arranged in a specific sequence which is decided by the genetic code present in the DNA molecule. The polypeptide chain in a protein may be straight (primary structure) or may form helical coils (sec..
