Movement involves 3 basic mechanisms. They are amoeboid, ciliary and muscular. Amoeboid movement is typically found in amoeba, a unicellular animal. Amoeba moves by producing pseudopodia, which are cytoplasmic projections. This involves change in the shape of the cell body and ..

Mendelian Genetics - The biggest name in the entire history of genetics beyond any doubt is that of Gregor Johann Mendel (1822-1884). It was Mendel, more than any other scientist, who synthesized the basic principles of heredity into a body of knowledge that has formed the very core of mo..

In 1909, Sorensen introduced a term for expressing the concentration of hydrogen ions, which give an idea about the acidic and basic characters of the aqueous solution. This term was called 'pH' which means the 'power of hydrogen ions'. The pH is defined as "the negative l..

Nutrition and Its Types - The term nutrition includes the way an organism obtains its food and also the processes by which the nutrients in the food are broken down to simpler molecules for the utilisation by the body. Thus, the study of the process of nutrition in various organisms gives us an ..

Atomic structure - Although Dalton's theory of the existence of atoms was published in 1808 there was no clear idea of what an atom might look like until the early part of the twentieth century. With the advent of electricity and phenomenon of spectrum, experimentation underwent a change ..

Indicators - Indicators are the chemicals that when added to solutions show whether the solution is acidic or basic, by a sudden change of their colour. The common indicators used and the colour changes observed are mentioned belo..

In spite of many evidences, studies and theories, we are still not aware of how the evolution actually occurs. If we go backwards at some point in the history of the earth it would have consisted of only the basic elements, the non-living materials like the air, water, sunlight etc. It i..

Molecular orbital theory was proposed by F. Hund and R.S. Mulliken in 1932. The basic idea of molecular orbital theory is that atomic orbitals of individual atoms combine to form molecular orbitals. The electrons in molecules are present in the molecular orbitals, which are asso..

The greatest contribution of Linnaeus to the natural system of classification is that he recognised species as the basic natural unit of classification. He used four specific categories in his classification namely class , order , genus and species . He divided the kingdom into many small..
