Gastrulation is an important dynamic process in the development of the zygote which involves movement of cell masses from the surface of the blastula to their definitive positions in the embryo and their three primary germinal layers i.e., ectoderm, endoderm and mesoderm. These movements ..

Example 19: The ozone in the ozone layer protects the earth from harmful ultraviolet radiation by trapping these radiations. This ozone layer has been thinning gradually and poses potential health hazards for the future. The thinning of ozone layer has been attributed..

In a game, a target is moving randomly on a vertical screen of length 8 m and height 9 m. A light source placed at 2 m in front of the board can be turned on with a switch. If the target is found with in the lighted portion of the screen a prize is won. Light is passed through a circle of..

Ozone (O 3 ) - Ozone is an allotropic form of oxygen. Its molecular formula is O 3 and molar mass is 48 g mol - 1 . Schonbein (1840) concluded that Van Marums observations in 1785 of a peculiar smell, when an electric discharge was passed through oxygen (or air), was in fact a n..

Let us refer to a circuit consisting of two switches p and q connected in series with a lamp and battery as shown in figure. The lamp will glow, only if switch p and switch q are closed. If we replace the word 'closed' by T and 'open' by F, the switch will..

Formation of 3 Germinal Layers - Gastrulation is an important dynamic process in the development of the zygote which involves movement of cell masses from the surface of the blastula to their definitive positions in the embryo and their three primary germinal layers i...

2 layer test for detecting bromine and iodine A small quantity of sodium extract is boiled with dilute HNO 3 for 1 to 2 minutes and cooled. A few drops of carbon disulphide (CS 2 ) and 1 to 2 mL fresh chlorine water are added and shaken. Appearance of orange color in the..

Who has not seen the damaging effects of rusting of iron! During the process of rusting the oxide that forms is brittle and chips off from the surface. This exposes yet another layer below to the deleterious effects of moisture and air. Thus, rusting destroys the metal layer by ..
