A.
As practised by scientists working with animals, cloning involves using a micro-manipulator to remove almost all the egg’s own genetic material — hollowing it out, in effect — and to insert a complete set of genes taken from the adult cell of the person being cloned. There is no evidence that human clones exist yet, born or unborn. That does not mean it will never happen — or has not already happened. Anyone with a little embryology experience and a well equipped laboratory could at least have a crack at it.
B.
According to the Eurobarometer survey, which measures attitudes to science and technology, more than one-third of Europeans believe that science brings more benefits than harm. However, while people are generally in favour of science and technology, there are concerns about the risks associated. According to the study, 86 per cent of young people think that there's a health risk involved in living near a nuclear power plant.
C.
Electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons and with electronic devices. Today many scientific and technical disciplines deal with different aspects of electronics. It can safely be said that not a day passes without the appearance of some new electronic device or some improvement in existing electronic devices.
D.
Now run down mobile phone battery can be recharged by hand. You save electricity, and you don't have to be near a power point. Several companies now produce chargers that work by turning a small handle. Inventors are also looking into ones that will charge automatically as you walk along. Apart from their convenience and environmental friendliness for everyone, the hand chargers could be invaluable in developing-country villages where mobile phones are increasingly used for vital communications.
E.
Electronic instrument is any musical instrument that produces or modifies sounds by electric, and usually electronic, means. The electronic element in such music is determined by the composer, and the sounds themselves are made or changed electronically. Instruments such as the electric guitar that generate sound by acoustic or mechanical means but that amplify the sound electrically or electronically are also considered electronic instruments. Their construction and resulting sound, however, are usually relatively similar to those of their nonelectronic counterparts.
F.
Science has always had a double function: not only to increase our knowledge, but also to increase our power — the power to change our world, for better or worse. The upward spiral of scientific knowledge and technological know-how of the last hundred years or so has made this particularly obvious. Even those scientists who themselves are only interested in expanding the frontiers of human knowledge, are finding it increasingly difficult to close their eyes to the potential uses of their discoveries.
G.
"The discovery of a new dish does more for the happiness of humanity than the discovery of a new star," one expert on fine food has remarked. Modern cooking is big business. It reflects centuries of experimentation, invention and scientific discovery. A number of food-processing innovations have even resulted in new products, such as concentrated fruit juices, freeze-dried coffee and instant foods. A microwave oven cooks food by means of high-frequency electromagnetic waves called microwaves. A microwave oven is a relatively small, boxlike oven that raises the temperature of food by subjecting it to a high-frequency electromagnetic field.
