biology

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 l..

Cancer is characterised by uncontrolled growth and division of certain body tissues, so forming a tumour. It is one of the major killers toda..

The numerical strength and biomass of organisms affect the functioning of ecosystem. In ecosystems, the biotic communities usually contain a few common species represented by a large number of individuals or by a large biomass and a comparatively large number of individual species occurring in sma..

Conversion of nitrogen into compounds is essential by combining with carbon, hydrogen and oxygen before it can be absorbed by the plants. This is known as nitrogen fixation. The micro-organisms which can fix atmospheric nitrogen can be classified into two main groups: i) Symbiotic micro-organisms i..

Internal respiration is also called tissue respiration or cellular respiration. 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 is called cellular respiratio..

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 eve..
