When the land is covered with vegetation, the roots of the plants and trees interlock and interlace to bind the soil particles. This helps in two ways: does not allow the soil particles to be carried away by wind or water does not allow free flow of water over the soil whi..

Cancer Biology and Therapy - Cancer is characterised by uncontrolled growth and division of certain body tissues, so forming a tumour. It is one of the major killers today. Normally cell division is a regulated process. Mature cells are replaced by new cells produced by cell division and ..

There are many pollutants like the DDT that are not bio-degradable. These accumulate in the organisms and cause serious health problems. The contamination of water with these pollutants results in their entry into the microscopic plants and animals. These organisms are fed upon by higher aquatic li..

As the complexity of the individuals, plants or animals increases the different cells and organs become separated from each other by greater distance. Thus it becomes necessary to have a system by which the different parts of the organisms can function as a single unit. This is possible o..
