Mechanism of cleaning action of soap |
| Answer» \tThe molecules of soap are sodium or potassium salts of long chain carboxylic acids.\tA soap molecule has a tadpole-shaped structure.\tAt one end (long non-polar end) of the soap molecule is a hydrocarbon chain insoluble in water but soluble in oil.\tAt the other end (short polar end) of the soap molecule, there is a carboxylate ion, which is hydrophilic, i.e. water soluble but insoluble in oil.\tSoap on mixing with water forms a concentrated solution and causes foaming.\tThe long non-polar end of soap gravitates towards and surrounds the dirt and absorbs the dust in it.\tThe short polar end with the carboxylate ion turns the water away from the dirt.\tA spherical aggregate of soap molecules is formed in the soap solution in water and is called a micelle.\tThe soap molecule thus helps in dissolving the dirt in water and we can wash our clothes clean. | |

How evolution and classification are related |
| Answer» The cell is the basic unit of life in all organisms. The characteristics in the next level of classification would be shared by most, but not all organisms. A basic characteristic of cell design that differs among different organisms is whether the cell has a nucleus. Bacterial cells do not, while the cells of most other organisms do. Among organisms with nucleated cells, which ones are unicellular and which ones multi-cellular? That property marks a very basic difference in body design, because of specialisation of cell types and tissues. Among multi-cellular organisms, whether they can undertake photosynthesis or not will provide the next level of classification. Among the multi-cellular organisms that cannot do photosynthesis, whether the skeleton is inside the body or around the body will mark another fundamental design difference. We can see that, even in these few questions that we have asked, a hierarchy is developing that allows us to make classification groups. | |

why do planets do not twinkle? |
|
Answer» And they don\'t appear as point sized sources of light but as a cluster of point sized lights as a result the greater refraction in some parts is equalled by less refraction other parts and thus nullifying the twinkling effect. Cause the planets are near than the star to the earth. They are collection of point source of light so atmosphere is not able to create varition in the light coming frm planets Because planets are very near from the Earth , due to this no atmospheric refrection takes place . Because they are not far as star |
