It is the most important parameter indicating the pressure of population on land, water and other resources. Usually, higher population density (expressed as number of people (square kilometers) is found in urban areas than in rural areas. Regional disparities of density of populati..

It is another highly specialised animal tissue. It is a derivative of mesoderm. The specialisation in connective tissue is for various specific functions. Following are some of the functions of connective tissue: It connects and binds various other tissues and organs. It forms a protective covering..

Earth's crust is rich in inorganic materials . It includes ores, that are used on a large-scale to yield metals such as iron, aluminium, copper, tin, nickel, silver, gold, platinum etc. These minerals are very useful in industrial and technological growth. Some of the metals are used as catalysts, ..
