переведите пожалуйста текст правильно Every human being begins life as a single cell, a fertilized egg, by the time reachers adulthood, the body consists of 100 trillion cells. The cell is a fundamental component ol all living thing. As cells deteriorate , people age. As cells malfunction, people get sick. If cells were better understood, people might live longer and stay healthier. And thanks to a recent series of extraordinary breakthroughs, scientists arc beginning to leam more about them. One of the molecular biologists says that we are on the verge of a revolution in the understanding of cells. Scientists discovered three centuries ago that living things contain cells, but only in the last three decades have they begun to piece together the puzzle of how cells operate . They know a few fundamental things: every single adult cell (except ova and sperm) contains the same set genes as the original cell. Still cells come in all shapes, sizes and functions: slim nerve cells more than 3 feet long and about 1 forty-thousandth of an inch wide: transmit impulses between the limbs and the brain: red blood cells 3 ten-thousandth of an inch in a diameter cany life - giving oxygen around the body. But researchers remain baffled by arcane chemical mechanism that enables particular genes in different cells to switch themselves on and off perform differently in varying circumstances . Each of those trillion cells functions like a walled city. Power plants generate the cell's energy. Factories produce proteins, vital units of chemical commerce . Complex transportation systems guide specific chemicals from point to point within the cell and beyond. Sentries at the barricades control the export and import markets, and monitor the outside world for signs of danger. Disciplined biolojgical armies stand ready to grapple with invaders. A centralized genetic government maintains order. Toxic garbane. Cells occasionally go wrong. Recycling systems can break down, overloading the cells with their own toxic garbage the result is the fatal Tay-Sachs disease, or some similarly horrendous genetic ailment. Confused by erroneous information, internal factories can add many chemicals to an already abundant supple that they eventually flood the whole body: the resulting accumulations of cholesterol lead directly to cardiovascular disease. A breardown in communications between the nuclei of cells and their outer borders can produce the unrestricted growth that causes cancer. Even if they operate smoothly, normal cells eventual succumb to old age -the process of biological decay that alters the cells and kills organism of which they for the basic units. Biologists think they eventually can treat many of defects by turning the intricate machinery in each cell to the patient's advantage. For instance . chemicals find their way to appropriate places in the cells through what scientists call *‘zip:' code". To overcome genetic diseases that leave cells bereft of vital chemicals , biologists might manufacture the chemicals in a test tube, attach the proper chemical address to them, and inject them into the dody- knowing that they will end up where they will do the most good. Similarly, to treat certain forms of cancer, scientists are learning to manufacture digestive sacs within the cells known as lysosomes . A cell ordinarily will reject many poisons . But if a drug-intended to poison a cancerous cell-is disguised with food, it might be accepted by the cell and released by the lysosomes .

помогите пожалуйста!! Read the text. Then mark the sentences as True (T) or False (F). Dear Editor, We represent the Young Journalists Club and we would be happy to publish some of our articles in your journal. The topics we study refer to teenagers' life. We run different surveys and questionnaires which help understand what teenagers are interested in, what they care for, and what they are indifferent to. Most of our research is on political and cultural issues, and we want to find out how competent contemporary teenagers are in those topics. We certainly don't ignore environmental issues and human rights problems and try to display a wide diversity of views and opinions. Lately we've been studying the TV topic, i.e. (то есть) what teenagers watch on TV and what TV programmes they enjoy. Forty teenagers, aged 14-16, were interviewed, and we got some curious results. Here are some of them. About 35% of the interviewed said that they don't watch the news at all. “I don't watch the news,” said Julia Smith, one of the typical representatives of that group, "they speak either about wars or terrorist attacks. If I watch it, I feel down and scared..., so... I don't watch it at all." 65% watch the news occasionally and randomly, and were not able to name any programme they trust. They confuse Presidents and Prime Ministers, and they are not sure about the regions of armed conflicts, and don't know what the word "summit" means. However, about half of our respondents mentioned that they would like to feel more confident about political issues, and that it would be useful to have some classes on political literacy (грамотность) in the school curriculum (учебный план). The survey revealed some unexpected things. For example, most teenagers are not really keen on thrillers and action films. They say that they prefer point-and-shoot computer games to action films. As for TV, about 60% of our respondents claim that they would like to see more educational, cultural and popular science films on TV. Scientific breakthroughs, new technologies, mysteries of the past and the present, ancient civilisations are very welcome. These topics have always been a great attraction for teenagers of all generations. In conclusion we would like to thank you for the time you gave to our letter. If you find our topics of some interest to your journal and your readers, we would be happy to present the full texts of our projects and articles, and discuss our possible cooperation.
