Many industrial organic acids can be manufactured from large scale culture of microbes. Acetic acid is produced by bacterial fermentation of ethyl alcohol by Acetobacter bacilli. Lactic acid is produced by bacterial fermentation of lactose by Streptococcus lactii Citric acid is produced b..

The different types of cells in the body of a multicellular organism are specialised for different functions. Yet, we see an autonomy in the cells in carrying out some of the fundamental biological processes such as respiration, utilisation of food energy, synthesis of macromolecules, eli..

Organ Transplants and Antibodies - Organ transplantation is defined as the transfer of organs (like kidneys, heart liver etc) from one person to another. An organ transplant always involves a donor - who donates an organ and a recipient - who receiv..

Heart - The efficiency of the heart decreases with increasing age. In a 70 year old man, the heart pumps only 65% blood per minute as compared to a 30 year old man. Oxygen uptake by blood - Oxygen uptake is reduced with advance in age. Decrease of blood volume - The production of ..

Importance of Diazonium Salt in Synthetic Organic Chemistry - Aryl diazonium salts constitute intermediates that can be used to synthesis many classes of organic compounds especially aryl halides in the pure state. For e.g., 1,2,3 - Tri bromobenzene is not formed in the pure sta..

1) Decomposers like Aspergillus (aerobic fungi), Neurospora (aerobic fungi) and Escherichia (anaerobic bacteria) act on the dead and decaying organic matter of plants and animals, releasing hydrogen sulphide (H 2 S) to the environment. 2) Heterotrophic bacteria like Desulfavibrio and Ace..

Haploids are organisms, whose cells contain haploid number of chromosomes - as against normal diploid number of chromosomes. Haploid cells are usually found in gametes of any organism. But when entire plant body contains haploid cells - it offers a great advantage as such plant..

Aryl diazonium salts constitute intermediates that can be used to synthesis many classes of organic compounds especially aryl halides in the pure state. For e.g., 1,2,3 - Tri bromobenzene is not formed in the pure state by direct bromination of benzene. But it is obtained by a sequence of..

Primary and Secondary Productivity - 'The amount of organic matter or biomass produced by an individual organism, population, community or ecosystem during a given period of time is called productivity'. Primary production refers to all or any part ..

Introduction - All living organisms need food for their existence. They need food for their growth, repair of tissues, energy and also protection against diseases. The various components of food are proteins, carbohydrates, fats, vitamins, minerals, roughage and wate..
