Evolution
1. A central organizing concept in biology is that life changes and develops through evolution, and that all life-forms known have a common origin. Introduced into the scientific lexicon by Jean-Baptiste de Lamarck in 1809, Charles Darwin established evolution fifty years later as a viable theory by articulating its driving force: natural selection. Evolution is now used to explain the great variations of life found on Earth.
Darwin theorized that species and breeds developed through the processes of natural selection and artificial selection or selective breeding.
2. The evolutionary history of the species – which describes the characteristics of the various species from which it descended – together with its genealogical relationship to every other species is known as its phylogeny. Widely varied approaches to biology generate information about phylogeny. These include the comparisons of DNA sequences conducted within molecular biology or genomics, and comparisons of fossils or other records of ancient organisms in paleontology.
3. The theory of evolution postulates that all organisms on the Earth, both living and extinct, have descended from a common ancestor or an ancestral gene pool. This last universal common ancestor of all organisms is believed to have appeared about 3.5 billion years ago.

What is the essence of the evolution theory?
Варианты ответов
  • It found out that the last common ancestor of all organisms have appeared about 3.5 billion years ago.
  • It implies that all organisms existing on the Earth have a common ancestor or an ancestral gene pool.
  • The development of species and breeds influences the processes of natural or artificial selection.
  • Life can be changed and developed through evolution as all living-beings have a common ancestor.

Evolution should be investigated from the historical point of view as it describes the species features depending upon their long-term genealogical relationships.
Scientists put forward different evolution theories but all of them point out that evolution plays an important role in the life of all living beings.
The founder of evolution theory, Charles Darwin, established evolution in 1859 as a viable theory by formulating its driving force: natural selection.
According to the theory of evolution all organisms on the Earth are of a common origin and are constantly changing and developing.

Water is not used in refrigerators. Why?
Water is not used in refrigerators because it evaporates too slowly. Ether, another refrigerant, is never used in domestic refrigerators since it is both poisonous and inflammable. However, it is sometimes used for industrial refrigeration because it evaporates very fast. Freon is usually used in domestic refrigerators as it evaporates fast, is non-toxic, and non-flammable.
Because it evaporates fast.
Because it is poisonous.
Because it is inflammable.
Because it evaporates too slowly.

Electromagnetism and gravity are two basic forces of nature. They are very similar and scientists are trying to unify them. Electromagnetism works in small objects – it attracts the electrons from the atomic nucleus and maintains them in place. Gravity works with big objects – the pull of gravity from the nucleus of the Earth maintains our atmosphere in place. Both, the electrons and the Earth, spin and generate an electric and magnetic field around them. These fields make up our planet’s electromagnetic shield.

Those seeking employment will want to investigate all available possibilities. The following are the main sources of information about job vacancies.
– Job centers.
– Employment agencies.
– Local careers officers.
– Newspaper advertisements.
– Friends and relatives.
Advertisements are the most common way of publicising a job vacancy and inviting applications. Prospective applicants should read the advertisement carefully. Not only it will give important information about the job and the firm, but it may also offer clues of what should be included in the letter of application.
In some cases it may be acceptable to type a letter, in others the advertisement may state that the application should be in “first hand”, in which case the letter should be handwritten, preferably on plain paper. It is sensible to make a rough draft of the proposed letter before writing it out in detail.
