MICRO ORGANISMS : Micro organisms are classified into four major groups.these groups are bacteria,fungi,protozoa viruses are also microscopic but are different from other microorganisms.the reproduce only inside the cells of the host organism,which may be a bacterium,plant or animal.Common ail- mets like cold , influenza(flu) and most coughs are caused by viruses,serious diseases like polio and chicken pox are also caused by viruses.   Diseases like dysentery and malaria are caused by protozoa whereas typhoid and Tuberculosis (TB)are caused by bacterial diseases.

WHAT IS IR : BRIEF: IR IS THE EXPANSION OF INFRARED  RADIATION  WHICH EMITS RADIATION WITH THE HELP OF ELECTRICITY. HOW IT WORKS: INFRARED RADIATION IS PRODUCED VERY MINUTELY SO THAT IS NOT AFFECTING BY ORGANISMS.THESE RADIATIONS ARE MADE TO TRANSMIT DATA AND THIS RADIATION IS PRODUCED BY A LED CALLED IR SOURCE OR IR TRANSMITTER .THIS IR TRANSMITTER PRODUCES ELECTRIC PULSES WHICH IS IN THE FORM OF 0 AND 1 WHICH IS TRUE OR FALSE. THESE 0 AND 1 ARE RECEIVED IN THE OTHER SIDE CALLED RECEIVER.THIS RECEIVERS GET THOSE 0 AND 1 FROM THE IR WHICH IS TRANSMITTED IN THE AIR.AFTER RECEIVING 0 AND 1 FROM THE RECEIVER,IT CONVERTS AND IT WILL OUTPUT'S IT DATA . WHERE IT IS USED: IR IS USED IN SMARTPHONES, TV REMOTES,MODERN FM'S AND MANY MORE WHICH IS IN COMMUNICATION INDUSTRIES. INTERESTING FACT : IR LIGHTS CAN BE SEEN ONLY WITH THE HELP OF A DIGITAL CAMERA

BRIEF: HAVE YOU EVER WONDER HOW SUN EMITS LIGHT THROUGHOUT THE DAY?  HERE IS YOUR ANSWER: THE SUN TAKES UP A CHEMICAL REACTION CALLED"NUCLEAR FUSION". IT IS THE FUSION OF TWO OR MORE SUBSTANCES TO FORM A NEW SUBSTANCE OR SUBSTANCES OR EVEN A NEW ELEMENT.

HOW A MOTOR WORKS ? DEFINITION: An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. HOW IT WORKS: The basic idea of an electric motor is really simple: you put electricity into it at one end and an axle (metal rod) rotates at the other end giving you the power to drive a machine of some kind. ... When an electric current starts to creep along a wire, it creates a magnetic field all around it. TYPES: Some of the most common electric motors used today include: AC Brushless Motors.   DC Brushed Motors.   DC Brushless Motors.  Direct Drive.  Linear Motors.  Servo Motors.   Stepper Motors. BRIEF: AC Brushless Motors AC brushless motors use the induction of a rotating magnetic field in the stator to turn the rotor and...
