Division: Angiospermae Class: Monocotyledonae Series: Coronarieae Order: Liliflorae Family: Liliaceae It is commonly called Lily family. It includes about 250 genera and 3700 species that have a cosmopolitan distribution. Around 200 species are available in Indi..

Explanation of Induction - When the positively charged body is brought near the two cans A and B, the electrons (-ve charges) from both the cans are attracted and get concentrated on B which is near R. The can A which has lost the electrons is left with an equal amount of positive..

When the rod X with positive charge on it is brought near C [figure (a)], the negative charges get attracted and they get concentrated on the cap C. On the other hand, the positive charge gets repelled and they get concentrated at the distant end on the leaves L and M. The leav..

Heisenberg, in 1927 pointed out that it is not possible to measure simultaneously both the momentum (or velocity) and the position of a microscopic particle with absolute accuracy. Mathematically this may be expressed..

Electronegativity is the tendency of an atom to attract electrons towards itself in a molecule of a compound. The value of electronegativity of an element describes the ability of its atom to compete for electrons with the other atom to which it is bonded. Electronegativity is however not the prope..

Characteristics of a Food Chain - In a food chain, a) there is repeated eating in which each group eats the smaller one and is eaten by the larger one. Thus, it involves a nutritive interaction between the biotic components of an ecosystem. b) the plants and animals which depend successively on one..

Most of plants and animal cells respire aerobically, that is, in the presence of oxygen. However, there are certain microbes that respire in the absence of free oxygen. This respiration is called anaerobic respiration. It is also called fermentation. Among plants, it takes place in yeast, bacteria ..

. The bottom block will sail out from under, and the rest of the stack will not be toppled but will drop down still in a pile. It is not immediately obvious that a body moving with uniform velocity in a straight line tends to go on moving forever without coming to rest. The fact is that n..
