Digestion is the process of break down of complex food substance into simple molecules.  Digestion is carried out by our digestive system by mechanical and biochemical method. The digestive system consists of alimentary canal and the associate glands. The process of digestion is accomplished by mechanical and chemical processes. The buccal cavity performs two major … Read more

Applications of atmospheric pressure Drinking Straw  When drinking with a straw, one has to suck the straw. This causes the pressure in hte straw to decrease. The external atmospheric pressure, which is greater, will then act on the surface of the water in the glass, causing it to rise through the straw. Subscribe on YouTube … Read more

Microwave ovens are so quick and efficient because they channel heat energy directly to the molecules (tiny particles) inside food. Microwaves heat food like the sun heats your face—by radiation. A microwave is much like the electromagnetic waves that zap through the air from TV and radio transmitters. It’s an invisible up-and-down pattern of electricity and magnetism that races through the air at the speed of light (300,000 … Read more

Cell structure and its functions Cell is the smallest structural and functional unit of an organism, which is typically microscopic and consists of cytoplasm and a nucleus enclosed in a membrane. Structure of cell The cell is a basic unit for life forms. As well as enabling sophisticated control of biochemical processes by providing compartments … Read more

:  A fast breeder reactor (FBR) breeds more fuel than it consumes that is it produces more plutonium than it consumes while generating power. For a uranium scarce country like India, it is an attractive technology. Plutonium produced in the thermal reactors as spent fuel is ideally suitable as the fuel material for use in … Read more

The spinal cord, running almost the full length of the back, carries information between the brain and body, but also carries out other tasks.  From the brainstem, where the spinal cord meets the brain, 31 spinal nerves enter the cord.  Along its length, it connects with the nerves of the peripheral nervous system (PNS) that … Read more

A quantum computer employs the principles of quantum mechanics to store information in ‘qubits’ instead of the typical ‘bits’ of 1 and 0.  Just as a bit is the basic unit of information in a classical computer, a qubit is the basic unit of information in a quantum computer.  It takes advantage of the strange … Read more

Reflex action is an immediate involuntary response to a stimulus. In an involuntary response, a sensory impulse on reaching central nervous system is itself returned to a specific effector as a motor impulse without neuronal analysis and integration. Reflex responses occur below the level of consciousness. Reflex actions are sudden and autonomic. For instance, if … Read more
