Traces of metal is necessary for the human and animal system to function efficiently. Some of the important metals required are iron, copper, zinc, sodium and potassium. Iron metal is a constituent of haemoglobin in blood which carries oxygen to various parts of the body in huma..

Nitrogen - Nitrogen forms nearly 78% of the volume of air. Earlier, the useful significance of nitrogen was not known and it was considered to be inactive. At that time, nitrogen was considered important only because it was known to moderate the processes of ..

Living Beings are Organised - Organisation refers to a kind of structure or system or situation where the smaller components become arranged into larger ones in a hierarchical order of complexity, to co-ordinate with one another in performing common functions or achiev..

Functions of Circulatory System - The functions performed by the circulatory system in all animals are 1) Transport of nutrients like glucose, amino acids, vitamins, minerals 2) Transport of oxygen from the organs of respiration to the body cells. 3..

. Thus, state of the system may be defined as its conditions of existence of the system when its macroscopic properties have definite values. When the state of a system changes its macroscopic properties also change and acquire new definite values. The macroscopic prop..

State of the system implies the conditions of its existence. In order to understand it, let H 2 O be considered as a chemical system. H 2 O can exist in three physical states; ice, water and steam depending upon the conditions of temperature and pressur..

Introduction - Functional groups containing nitrogen are present in a variety of naturally occurring and man made organic compounds. These functional groups impart physico- chemical characteristics to these molecules. These groups are responsible for their unique chemi..

The nitrogen cycle is complex as it depends on the activities of various bacteria. Nitrate in the soil is built up by plants into protein which is then passed on to animals, which eat the plants. The nitrogen from the protein is returned to the environment as ammonia (ammonifica..
