function introduction

Every organism, whether its body is unicellular or multicellular, is capable of performing all vital functions such as respiration, ingestion, excretion and reproductio..

The steam engine uses the power generated from steam pressure to move. Coal is used in furnaces to heat water in the boiler to generate steam. Steam pressure makes the wheels of the engine move. As coal is burnt, smoke is emitted and ash is left behind in the furnace. Smoke is let off through the c..

The concept of limits leads to define and describe continuity and derivative of the function. The continuity of a function has practical as well as theoretical importance. We plot graphs by taking the values generated in the laboratory or collected in the field. We connect..

All organisms require energy in order to stay alive. Energy is utilised to do the various bodily functions such as breathing, ingesting and digesting food, excreting, reproducing, locomotion, etc. Energy is obtained from food. Thus the process of intake of food is vital for the survival o..

An animal performs all its life functions with an aim to be alive till it matures and reproduces. Reproduction is the ability of living organisms to produce new individuals similar to themselves. Reproduction ensures perpetuation and survival of their species. It leads to an increas..

The simplest organic compounds are hydrocarbons. All organic compounds can be derived from hydrocarbons by substituting a hydrogen atom with a suitable functional group. Replacing a hydrogen atom by a OH group in a hydrocarbon, gives an alcohol: replacement of H atom in a hydrocarbon by C..

All organisms require energy in order to stay alive. Energy is utilised to do the various bodily functions such as breathing, ingesting and digesting food, excreting, reproducing, locomotion, et..

All living organisms require a continuous supply of energy for carrying out various functions. The main source of energy for all the functions, in all living organisms is cellular respiration. Cellular respiration is an energy releasing, enzymatically controlled catabolic proces..

A tissue is a group of cells having a common origin, similar structure and performing a common function. Tissues are characteristic of advanced multicellular animals, commonly called as eumetazoans. They are true multicellular animals where the body cells aggregate to form tissues, ..

The important characteristic of the gene is to store and express the genetic information that will contribute towards the phenotype, and will be passed on to successive generation. The idea that genes control the metabolism was put forward as early as 1902 by Gannod. He studied several human disord..
