English is the study of the English language. The goal is to improve communication skills by practicing listening, speaking, reading, writing, and understanding language rules like pronunciation, vocabulary, and grammar.
In 1962, a team of scientists produced a special radio station that had a range of fifteen moles. Even though communication was being accomplished in space at a range of more than a million times this distance, the new radio station caused must excitement among scientists. The reason: its power supply was ‘battery ‘made of bacteria. For the first time, practical amounts of electricity were being produced by a form of life and put to use.
‘biocell’, the new power supply had a liquid fuel containing tiny forms of life that changed the fuel directly into electric energy. This was far more than an interesting experiment. The biocell is being developed as producer of electricity for radios, for signals to guide ships, for lighting and for other uses. Thought the working biocell is only a few years old, some scientists feel that it will one day produce power cheaply as is now being done by other methods, and that the biocell will use materials that would otherwise be considered a waste. Early biocells were powered with sugar, but a wide range of fuels can be used. Work is being done using sea water to feed the bacteria.
Electricity from living cells is no new idea. Man experienced the strange ‘shock ‘produced by some fish even before electricity was really discovered. Then in time, there were other discoveries. Benjamin Franklin found that lightning in the sky was electricity. Lulgi Galvani found some electricity in the muscles and nerves of animals. Bust the African catfish produces far more electricity than most other living creatures. And another fish, the electric eel, well named, for it has an even greater electric charge. Research works also discovered that even humns produce small amounts of electricity in their bodies. Our hearts produce a very small amount that can be measured, so do our brains. The biocell is completely new in the field of power production and, as yet, no mass-produced models have begun to replace the older types of batteries. It might be wondered, and then what the excitement is all about.

While political and social changes may appear to be distinct phenomena, they are analytically inseparable. Political and social changes refer to alteration or transformations in human behavior, norms and politico-social institutions. Such changes are often a collective response to the need to change, or as a tacit recognition of a shift in the prevalent power relations in the society. Therefore, the coming to power of a new set of rulers, or the establishment of new structure and processes of governance broadly typifies socio-political changes.
It is important to note that changes can either be positive or negative. In most cases, political and social changes are caused by certain factors or reasons. This push people to collectively organize themselves to struggle for a change in the existing power relations. Another reason is to capture political power in the hope of making life better for the generality of the people. If politics is defined as who gels what, when and how; It then implies that political change refers to an alteration in the form of power and the identity of the group or class which controls the wields states power.
