The study of various aspects of life activities requires the use of certain techniques and analytical instruments. Physical and chemical sciences have helped scientists in developing some tools and techniques with the help of which biologists have been able to get a clearer insight into the life pr..

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 differentiation. Due to altered gene ..

Biology invariably uses knowledge and techniques from other branches of science, to solve its complicated life processes. Most of the recent discoveries and inventions in biology have resulted from the joint endeavour between biology and physical sciences and even ..

It includes the exchange of gases between the cells and the blood and the breakdown of food in the cells. The bio-chemical processes involved in respiration which break down the substrate to release energy take place in the tissues within the cells of an organism. Thus, this biochemical ..
