The students of Environmental studies collected the data of the life span of Zebras from the zoological authorities which are as follows. 20, 12, 19, 22, 28, 30, 17, 25, 10, 23, 16, 18, 21, 32, 15, 14, 8, 22, 11, 13, 18, 20, 21, 19, 19 Find the average life span of a Zebra by constru..

. Such series demonstrate as to how various forms of life have changed gradually over a period of millions of years. As a result, the evolution of a number of animals such as horse, camel and elephant, has been clearly understood. Plenty of fossil evidence is now available so as to establish human ..

Formation of Image by a Plane Mirror - Ray Diagrams - The following rays are usually considered while constructing ray diagrams: A ray of light incident on a plane mirror at 90 degree gets reflected from the mirror along the same path. A ray of light falling on a plane mirror at any angle..
