Polydispersity index is the ratio of the weight and number average molecular masse..

The position of a point in a plane is determined by two coordinates. The method is as follows: Two mutually perpendicular lines (straight lines) XX' and YY' are drawn as shown in the figure. These straight lines are termed as coordinate axes, the one (usually drawn horizontally)..

Rectangular coordinate system - The position of a point in a plane is determined by two coordinates. The method is as follows: Two mutually perpendicular lines (straight lines) XX' and YY' are drawn as shown in the figure. These straight lines are termed as coordinate axes, the ..

Cell division is a method by which new cells are originated from pre-existing cells. The formation of daughter amoebae in amoeba, the development of sex cells and the growth of a young animal or plant into an adult, all involve cell multiplication. In order to multiply in number, cells un..

The plants upon which we depend for the food we eat, and for the oxygen we breathe, depend in turn upon the soil. A good soil supplies the plants with the mineral elements they use. Vigorous, highly productive plants can be grown in solutions of fertilizer minerals in the absence of soil. Mineral n..

Echolocation is a method of sensory perception by which certain animals orient themselves to their surroundings, detect obstacles, communicate with others and find food. Bats use echolocation to navigate in the dark and find food. A bat emits a series of short high-pitched ultrasonic wave..

Asia has 60% of global population and continues to dominate the global population in next 50 years. Some countries in Europe have negative or zero growth of population. In India, U.P is a populous state but density of population is highest in West Bengal, literacy rate and sex ratio is high..

It is very difficult to accurately weigh the number of atoms as they are extremely light and small and they cannot be seen. Indirect methods have been utilized to determine the absolute mass of an atom...
