Energy Flow - All living beings require a constant supply of energy for the various functions they perform. The energy is obtained from the sun. This energy is introduced into the biosphere by green plants by a process known as photosynthesis. Plants are able to trap this light energy and by the pr..

Satellite Communication - It is mainly done through geostationary satellites. These satellites are fitted with special devices. These devices can receive signals from an Earth station and transmit them again in different directions. These special devices are called transponders. A TV transmitter on..

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..

. As there is a natural plant-animal cycle, an equilibrium is set up and all living matter contains the same small proportion of 1 4 C as it occurs in the atmosphere. Once the plant or animal dies, the uptake of CO 2 by it ceases and the level of 1 4 C in the dead begi..

Summary Relations and Functions - A pair of objects, written in a specified order is called an ordered pair . A pair of objects, written in a specified order is called an ordered pair . For the ordered pair (a,b), a is called the first element and b, the second element. The ordered pairs (a,b) and ..

Summary - Reproduction is defined as the production of individuals of the same species, that is the next generation of the species. There are basically two types of reproduction - asexual and sexual. Asexual reproduction involves only one parent and the offspring is genetically similar to the paren..

Mediators amplify the signal in an expanding cascade of response. A single -subunit of insulin receptor, for example, activates many molecules of DG, and each protein kinase C molecule activated by DG will, in turn, activate many other enzyme molecules. DG and IP 3 are examples of second messenge..

Reasons for Mendel's Success - Many scientists earlier to the period of Mendel had attempted breeding experiments in both plants and animals. However, most of them failed to arrive at any specific conclusions or principles to explain the pattern of inheritance. In fact, many of these scie..

When pollutants like hydrocarbons and nitrogen oxides combine in the presence of sunlight, smog is formed. This is a mixture of gases and since it is formed by photochemical reactions, it is called the photochemical smog. The word 'smog' is derived from the two words - smoke and fog. It forms a ye..
