Question 1 - Question: How did the people react to see Cutie-Pie shown on T.V sets? Answer: The people were very fascinated by the extraordinary appearance of this extra terrestrial creature. They called him "Cute" because of his admirable rainbow-like coloured feathers. They wanted to cu..

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 the plotted poi..

An atom or a molecule is a very minute particle; the actual mass of an atom is extremely small. The mass of atoms extends from 1.67 x 10 - 2 4 g (hydrogen) to 4.0 x 10 - 2 2 g only. It is physically not possible to measure such small and light masses easily. In 1811, Avagadro suggested ..

The AM radio waves which propagate from one point to another following the surface of Earth are known as ground waves or surface waves. This type of propagation is called ground wave propagation or surface wave propagation. In ground wave transmission, the intensity of the signal falls with distan..

An organism, in which number of complete chromosome sets is more than the diploid number is called polyploid. It is usual practice to express the chromosome number of an organism in diploid, symbolically represented by 2n. In all sexually propagated crops, such expression is of ..

The apparatus is set as shown in figure 7.2. Copper turnings are taken in a round bottom flask. Concentrated sulphuric acid is added through the dropping funnel and the flask is carefully heated. Chemical reaction occurs and SO 2 vapours get displaced upwards. The sulphur dioxid..

Biotechnology is the use of technological procedures in the field of biology for obtaining products of commercial importance. Biotechnology is the use of technological procedures in the field of biology for obtaining products of commercial importance. Biotechnology has two main aspects gene..

Radiocarbon The 1 4 C so produced is eventually converted into CO 2 , which in turn is incorporated into plants and trees by the process of photosynthesis and then finds way into animals, which eat plants. As there is a natural plant-animal cycle, an equilibrium is set up and all living m..
