Genetic engineering
2009-12-22
It is estimated that humans have between 50,000 to 100,000 different genes; some of them are linked to particular diseases and conditions. Scientists have now identified nearly 4000 conditions that are limited to single defects in a person’s genetic code. Researchers all around the world are currently engaged in “The human genome project”, which aims to identify and define the function of every gene to be found in the human body. Through this they hope to locate errant genes, thereby getting a better understanding of every disease that is genetically transmittable and if possible find a cure for it. Genetic engineering, where by the defective gene sequence is cut and remodeled, is one route scientists might take. At present genetics can be a reliable predictor of who is likely to develop a particular fatal illness. Many feel that this information has the potential to cause as much harm as good, among the 10 percent of the population who may be affected. Some say that people would not be able to cope with the knowledge that they were likely to contract a terminal illness, but genetics argue that everyone has the right to know so that they could plan the rest of their lives. Some women who have been told that they are likely to develop breast cancer have chosen a surgery to remove the breast in order to increase their chances of survival. Genetic engineering is big business, and many experiments take place on animals. Fruit flies have been produced that they have extra eyes on their wings and legs; two years ago scientists grew an ear in a test tube and then transplanted on a laboratory mouse without immune system in order to see if it would be rejected. Harvard University has even patented its own mouse known as “nocuous” which has been genetically manipulated to develop cancer. Imutran, a Cambridge-based biotechnology firm, have produced a pig that is transgenic, from which they hope to be able to supply donor organs such as hearts that are in short supply for transplantation. The revelation that scientists at Cambridge University have successfully transplanted the hearts from genetically altered pigs into monkeys is the most wonderful news to have emerged from the world of medicine fro more than a decade. We are all to familiar with the bad side of science – here is a cause for being happy. The implications are stunning. We are witnessing the forward in human happiness. The chance now exists that hundreds of thousands of people, who are waiting for heart, liver and kidney transplants and would die because of the lack of donors, will now live. Suffers from many other diseases will also face hope. Not only will all those who need these major organ transplants be treated but whole new therapies will emerge. Many cancers, for example are now treated by chemotherapy or radiotherapy but in future it might be safer and more effective to just transplant the affected organ. Possibilities are nearly endless and truly amazing. Whole new era of health and longevity is now downing. Names of diseases: Appendicitis, bronchitis, cancer, chicken-pox, constipation – vidurių užkietėjimas, diabetes, diarrhoea – viduriavimas, hay fever – šienligė, hepatitis, indigestion – skrandžio skausmai, flu, insomnia – nemiga, leukaemia, measles – tymai, mumps – kiaulytė, tonsillitis – angina. Shortened one: Genetic engineering A general term for the direncted manipulation of genes, and usually used synonymously with genetic manipulation or genetic modification. A wide range of technologies are involved in this, but most involve the recombinant DNA techniques. Genetic engineering falls into several different categories depending on what is being engineered. Bacteria, yeast. This is ‘traditional’ genetic engineering (over 10 years old). Using recombinant DNA techniques genes are put into microorganisms to make them produce something we want, be it insulin, better beer or protein for food. Animals. Genetically engineered animals are usually called transgenetic animals. They are produced by a combination of fertilization techniques and DNA technology and produce animals that pass on their genetic modification to their offspring. Plants. Sometimes called transgenetic plants. They are created through the use of plant cloning technologies, which involve growing plants from isolated plant cells. Humans. Although the genetic engineering methods applicable to cows or mice are, in theory, applicable to humans, they have not been yet applied for obvious ethical reasons. Some experiments treating disease have been performed: these do not modify the germ cells. This is called gene theraphy rather than more public allarming term genetic engineering.
In our world are a lot of animals. Some of them live their usual life. Others are threatened of extinction. They live only in theirs specific areas. Some of them are just on extinction, but there are a lot of which number of population is really small. Animals which are on extinction are the following: stoats (šermuonėlis), seals (ruonis), white hares (baltasis kiškis), black storks and grass snakes. They are threatening of extinction because of some reasons. First and the most important reason is that these animals haven’t got fitted to them residence. They live in uninhabitable areas. They haven’t got specific food, and they can’t adapt to alterable living conditions. Second reason why there are endangered animals is that man's mastery over his environment is really huge. First here are a lot of factories and companies which are polluting air and water. Second there are cutting down forests on a mass scale. One more human’s harm is that hunters are hunting some animals for their fur, skin or bones. Animals are vanishing apace, and if we don’t take measures animals will disappear and it is unstoppable. So what should we done? First I think we have to try to reduce air and water pollution. We have to try to live cleanly. We ought to stop littering and using chemicals. Second way how to protect these vanishing animals is to transpose them to the zoo or into their specific and fitted areas. In these areas they can live their normal lives. To sum up I want to say that all of us have to understand that if these animals will disappear we can’t restore them.

Lithuanian flora consists of deciduous trees, coniferous wood, mixed forests and bushes. Deciduous trees are oak, birch, alder, lime and others. Fir and pine are from coniferous wood. Mixed forests compose the biggest part of Lithuanian flora. Many animals are involved in Red book in Lithuania. Hunters don’t think about damage which they make hunting animals. In my opinion, national parks and conservation areas are necessary in Lithuania. These places protect our forests from cutting, animals don’t disappear.

Here are facts showing the dangers of eating meat because of the large amounts of antibiotics fed to livestock to control staphylococci (commonly called staph infections), which are becoming immune to these drugs at an alarming rate. The animals that are being raised for meat in the United States are diseased. The livestock industry attempts to control this disease by feeding the animals antibiotics. Huge quantities of drugs go for this purpose. Of all antibiotics used in the U.S., 55% are fed to livestock.
Lithuania is a very beautiful country. It is very rich with many plants and animals. But of course we must save what we have. The most beautiful part of nature is our thick forests. They cover 27,9% our all territory. So we can admire our woods. But they are not like they were 5 or 6 hundred ago. Then our forests were just inpassable and full of different animals. But many people have cut these beautiful woods and now we have only 18,000 separate plots. But now when people understand the threat of extinction and many organisations plant new pine forests.

Nowadays the air, water and soil pollution have become a really big problem. Humanity thinks too little about natural resources and future of our descendants, as well as the world face, the disappearance of rainforests and global warming. The rapidly developing industry has polluted the air and the water. People, animals and plants are closely connected to each other. The usual order being broken, the nature starts to clean itself in a way that is harmful to the man himself.

Vitamins
2009-07-09
All living things, plant or animal, need vitamins for health, growth, and reproduction. Yet vitamins are not a source of calories and do not contribute significantly to body mass. The plant or animal uses vitamins as tools in processes that regulate chemical activities in the organism and that use basic food elements-carbohydrates, fats, and proteins-to form tissues and to produce energy.Vitamins can be used over and over, and only tiny amounts are needed to replace those that are lost.

About dinosaurs
2009-07-09
One of the smallest dinosaurs known, Compsognathus grew only about as large as a chicken, but with a length of about 60–90 cm (2–3 feet), including the long tail, and a weight of about 5.5 kg (12 pounds). A swift runner, it was lightly built and had a long neck and tail, strong hind… The Compsognathus is the smallest dinosaur in the Jurassic Period. It only ran on its two back legs. Its shape allows it to run fast and swiftly. This can help it to run from all the predators. Its top speed was twetny-five miles per hour. It was the size of a chicken. It was only two and a half feet long including the tail. its height was only one foot tall. It weighed only ten pounds.

Cat's
2009-07-09
A group of cats is referred to as a clowder, a male cat is called a tom, and a female is called a queen. The male progenitor of a cat, especially a pedigreed cat, is its sire, and its female progenitor is its dam. An immature cat is called a kitten (which is also an alternative name for young rats, rabbits, hedgehogs, beavers, squirrels and skunks). In medieval Britain, the word kitten was interchangeable with the word catling. A cat whose ancestry is formally registered is called a pedigreed cat, purebred cat, or a show cat (although not all show cats are pedigreed or purebred). In strict terms, a purebred cat is one whose ancestry contains only individuals of the same breed.

New Year
2009-07-09
New Year - conditional start of the Calendar year. Ancient Lithuanian, national holidays calendar, shows that the beginning of the New Year during ancient times had no fixed date. According to ethnographers’ thinking, the abundant agrarian rites with sun and fire elements of worship, winter’s burial, preparation for spring works traditions could signify the New Year start. Later the new Year was identified with Easter, which is bound with plant vegetation and start of outdoor work.

Everyone wants to live clean, nice and tidy. We like to look at somewhere and say: “What a niece place! How wonderful! Just like in heaven!”. But what are we doing to make the surrounding like this? To my mind just nothing… On the contrary – we do much more to destroy our environment. Living conditions in the world are getting worse and worse. Exhaust fumes and smoke from factories are polluting the air, trees are cutting down, and streets are full rubbish and grime. Furthermore rivers are being polluted by chemicals from factories too.

Pollution
2009-07-09
I’m going to speak about some kinds of pollution, for example air pollution or acid rain, water pollution. Now different kinds of trees, many of the animals, birds, fish are in serious danger. What should government do to stop the polluting, nowadays? First of all I would like to speak about water pollution There is no ocean or sea which is not used as a dump. Many rivers and lakes are poisoned, too. Fish and reptiles can’t live in them.

Feast of St.John
2009-07-09
From ancient times people marked the time of the return of the sun, the shortest and longest night. In olden times it was called the Feast of the DEWS, [ a.k.a. RASOS ]. When Christianity was established in Lithuania, the name was changed to Feast of St. John, according to agrarian folk calendar, the start of haying. The rituals of the longest day were closely related to agrarian ideas and notions.

Darbas apie fizines bausmes taikomas vaikams, jų pasekmės, kilmė, priežastys, įtaka auklėjimo raidai. Darbas susijęs su psichologija. Prievarta prieš vaikus egzistavo per amžius. Jos vertinimas ir supratimas skyrėsi ir skiriasi priklausomai nuo laikmečio, socialinio, kultūros - ekonominio lygmens. Visuomenėje pastaruoju metu vis daugiau dėmesio skiriama prievartos ir žiaurumo atvejų skaičiaus didėjimui. Pastaruoju metui vis dažniau viešumon iškyla, nors tik reti ir atskiri, prievartos prieš vaikus atvejai.

Drug
2009-07-09
Drug, substance that affects the function of living cells, used in medicine to diagnose, cure, prevent the occurrence of diseases and disorders, and prolong the life of patients with incurable conditions. Since 1900 the availability of new and more effective drugs such as antibiotics, which fight bacterial infections, and vaccines, which prevent diseases caused by bacteria and viruses, has increased the average American’s life span from about 60 years to about 75 years. Drugs have vastly improved the quality of life.

Do zoos serve a useful purpose, or are they unfair to animals? During the last few years there has been noticed a great development of zoos. Some people think that such places are entertaining or even needed. However in my opinion zoos should be banned for numerous reasons. The first argument against zoos, which I would like to present, is that in fact in most cases animals are kept there against their nature. Nowadays people are used to keeping animals at home, though these are just a few species and they have been domesticated for centuries.

Lithuania has nature and beautiful landscapes. And yet many plants and animals cannot survive without protected areas. We must protect nature from people - and for people. Any species can be leaded into extinct if they are hunted, polluted or infected. One of the smallest species vanishing in nature can cause irretrievable affect to others one’s. This is because all of species are involved into the natural chain of sustenance.
