Nitrogen Fixing Organisms - Some bacteria are known to fix the atmospheric nitrogen for their own biological activity. This natural phenomena is commercially utilized to increase the nutrient supply to crops. There are two types of nitrogen fix..

>The nitric oxide so formed then reacts with more oxygen to form nitrogen dioxide. Nitrogen dioxide so formed, gets washed down by rain and forms nitrates and nitrites in the soil. Plants absorb these of nitrates and nitrites from the soil and convert them into plant proteins. A..

We can think of a single fixed pulley as a lever of class I where the fulcrum is at the centre and the load and effort arm have the same length. (shown in the figure below) Fixed Pulleys If you pass a string over the pulley with one end carrying a weight and the other end attach..

: Rhizobium, a nitrogen fixing bacteria present in the roots of leguminous plants, fixes atmospheric nitrogen to the soil. Azotobacter and Clostridium are other free-living nitrogen fixing bacteria. Physical fixation When nitrogen..

The nitrogen cycle is complex as it depends on the activities of various bacteria. Nitrate in the soil is built up by plants into protein which is then passed on to animals, which eat the plants. The nitrogen from the protein is returned to the environment as ammonia (ammonifica..

Large amounts of free atmospheric nitrogen is however, fixed artificially by a number of methods. Three important methods ar..

Nitrogen Cycle - Nitrogen is an important structural component of many necessary compounds, particularly proteins. Atmosphere is the reservoir of free gaseous nitrogen and nitrogen compounds are found in bodies of organisms and in the soil. Living organisms c..

In this case, there will be a reversal of phase due to reflection. Let the incident wave be represented by the equation. The reflected wave will have the same magnitude of the amplitude, velocity and wavelength. Due to reversal of phase (i.e., a crest returning as a trough or vice versa) the sign o..

>When nitrogen is heated with calcium carbide at 800 o C to 1000 o C, nitrolim an important fertilizer is formed. Nitrogen is used in high temperature thermometers, as a refrigerant and in electric bulbs. Nitrogen cycle charts the circulation of nitrogen comp..
