Introduction - Biogeography reveals that living organisms (plants and animals) are found practically everywhere on this earth. The living components interact among themselves as well as with their physical environment like soil, air and water. The branch of biology, which deals with the r..

Replacement of hydroxyl group in carboxylic acids with a halogen, carboxylate, alkoxy or amino group gives functional derivatives of carboxylic acid known as acyl halides, acid anhydrides, esters or amides respectivel..

Health is considered to be the state of perfect functioning of body and mind, unhindered by diseases. Disease is the malfunctioning of the organism or part of it due to infection, inherent weakness or environmental stress, that upsets the normal physiological functioning of the ..

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 chemical reactivity patt..

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 poss..

Every organism, whether its body is unicellular or multicellular, is capable of performing all vital functions such as respiration, ingestion, excretion and reproduction. In multicellular organisms, because of the increase in body size, it is difficult for each cell to efficiently cope wi..
