... are the cause of great destruction and devistation in the area in which they occur. For example the Tri-State Tornado of 1925 occured in the Kansas, Oklahoma, and Texas States. This tornado was one of the largest tornados recorded in history. It killed nearly 625 people. However, the tornado which strikes closest to home has occured on what Canadians have come to know as "BLACK FRIDAY". The tornado of "Black Friday" touched down on July 31st, 1987 at 2:59 pm. (See appendix #2 for the torndo path). (See appendix #'s 4&5 for maps locating the disaster sights). 27 people were killed; 25 people died during the tornado and 2 died later in the hospital. Hundreds of other p ...

... or Maintaining Sleep). Several surveys have tried to pin down the exact cause of sleep problems. Of 1,000 households, one third had someone with current problems and in 42 percent someone had suffered from sleep disorders at sometime. Some doctor's polls have been revealing yet somewhat disparate. In one survey, roughly 19 percent of the patients seen by the 3,000 doctors had complaints of some type of . That figure may actually understate the case, for some say that more people in the United States visit doctors for help in getting to sleep than any other single complaint. It is also estimated that half of those not considered cs have a sleepless night on occasion, and a large but ...

... the head edging the jaws. Humpbacks have huge, mottled white flippers with rough edges that are up to one-third of its body length; these are the largest flippers of any whale. The humpback's genus, Megaptera, means "huge-wings," referring to its flippers. The flippers may have barnacles growing on them. The deeply-notched flukes are up to 12 feet (3.7 m) wide. Humpbacks have a small dorsal fin toward the flukes. DIET AND BALEEN Humpback whales (like all baleen whales) are seasonal feeders and carnivores that filter feed tiny crustaceans (krill-mainly Euphausia superba, copepods, etc.), plankton, and small fish (including herring, mackerel, capelin, and sandeel) from the water ...

... mica cemented together with felspar. These rocks are gradually weathered and broken down by the action of carbon-dioxide from the air dissolved in rainwater forming ‘kaolin'. This is further broken down to form other substances, ultimately resulting in the formation of Aluminium deposits. Where and how Aluminium is mined? Aluminium is never found in it's pure state until it has been refined. Aluminium is made when refining alumina, which is in turn found from the ore ‘bauxite'. Bauxite is often mined in the opencast method. Aluminium deposits are found in many countries, but the countries with significant deposits include: Guinea, Jamaica, Surinam, Australia and Russia. How is Alumini ...

... overhanging the water's edge, and plants with long thin, grassy foliage that grows in the shallows. These will all help to cover the water edge, which is almost never seen in a natural pond. Most nurseries sell aquatic plants. A pond that is meant to look natural requires much less maintenance than a formal pool, were clean, clear water is generally preferred. If the site has a low area, a pond is a good choice in almost any climate. Natural ponds will also suit almost any architecture, but they are not often effective on small site, particularly urban houses were a more formal water feature would look more appropriate. ...

... the Apodemus agreavius coreae mouse. Using the microscope, one could see the round microbes that were stacked in rows along the epithelial lining of the lungs (CDC website 6). Each infection still involved mild kidney infections. The same type of rodent always carried the virus, and people came in contact with the microbes through skin exposure or inhalation of infected animal feces or urine. Research continued on this virus and in 1981, it was first cultured in human cells. Many people were worried that since the virus was so prevalent in Korea that it possibly could be spread easily from boat to new land through trade. When rats were tested in various harbors throughout the Unit ...

... home and into the havoc that is ours. Millions of acres of beautiful land are destroyed daily to satisfy the needs of mankind. But has anyone contemplated the needs of our wildlife? When their homes are incinerated, where do they run for shelter? Where will wildlife obtain its food and oxygen if the sources are gone? Not much is done about our destructive ways, we sit back and let money and greed take power. The solution is just a whisper away. The preserved areas should remain untouched. Hunting should be outlawed in these protected lands. If a family is starving and has to resort to this brutal deed, then restricted areas should be permitted. Proper usage of trash and recy ...

... commercial forecaster, "Global air temperatures as measured by land-based weather stations show an increase of about 0.45 degrees Celsius over the past century. This may be no more than normal climatic variation...and several biases in the data may be responsible for some of this increase." - Satellite data indicate a slight cooling in the climate in the last 18 years. These satellites use advanced technology and are not subject to the "heat island" effect around major cities that alters ground-based thermometers. - Projections of future climate changes are uncertain. Although some computer models predict warming in the next century, these models are very limited. The effects of cloud ...

... 2 m tall; and weigh 90 kg. A gray kangaroo can clear more than 9 m (30 feet) at a bound and attain a speed of 48 kilometres per hour. The wallaroo, a smaller and stockier animal, may be dark gray to pinkish brown; it lives in rocky country throughout Australia except Victoria. These large kangaroos travel in groups (mobs) under the leadership of the largest male ("old man," or "boomer"), which dominates younger rivals by biting, kicking, and boxing. Each long, narrow hind foot has four toes. The short forelimbs are used almost like human arms, but the thumb is not opposable. Kangaroos possess soft, wooly fur, and some have stripes on the head, back, or upper limbs. All kanga ...

... organism and to furnish all descendants with protein-synthesis and hence the growth and development of the organism. So all living things on plant Earth contains the genetic material DNA and the structure of a DNA molecule or combination of DNA molecules determines the shape, form, and function of the offspring. 2)The term "genetic technology"(or genetic engineering) is the modification of the genetic properties of an organism by the use of recombinant DNA technology. By using this technology it is possible to alert characteristics of living organisms in specific ways. The chemical languages of DNA in all living thing are the same so it is possible to take one gene from one living thing ...
