.... in the late Cretaceous period, about 72 to 65 million years ago, toward the end of the Mesozoic, The Age of Reptiles . It was among the last of the dinosaur species evolve before the Cretaceous- Tertiary extinction 65 million years ago. BEHAVIOR: Triceratops was probably a herding animal, like the other Cartesians. This hypothesis is supported by the fining of bone beds, large deposits of bones of the same species in am area. Triceratops hatched from eggs, which may have been cared for by adults. Which threatened by predators, Triceratops probably changed into its enemy, like the modern-day rhinoceros does. This was probably a very .....

.... in saluting and blank fire charges, as the bursting charge of practice shells and bombs. Despite the fact that is called under one name, there are many different forms of . These are merely classified as how strong their reactions are, in other words, the size and power of their reactions. The most typical form of is the mixture of sulfur, charcoal, and potassium nitrate. Another form of this powder is known as the brown form, this is a mixture of saltpeter, charcoal, and sulfur. These pieces tend to look like little hexagonal or octagonal milk chocolate pieces. However these can be modified in a way to form a more harsh expl .....

.... second is the Steady State Theory. (Weinberg, 1977) The later hypothesis was created to replace the common belief that the universe was completely static. The expansion of the universe was discovered in 1929 when Edwin Hubble discovered that every galaxy in the universe was moving away from each other, this meant that the universe was expanding. Hubble found the movement of the galaxies by using a phenomenon known as the Doppler effect. This effect caused bodies moving away from an observer to have a "red-shifted" spectrum (the light spectrum of the body had been shifted closer to red) and bodies moving towards an observer to be "blue-shi .....

.... ride. Then the tension rose. In less than thirty-six hours, they would have to close a gap of four thousand miles at an altitude of 245 miles while traveling at 17,500 miles per hour, only to have to move within three inches and two degrees of a quickly moving, very fragile object in space. One small thrust of a poorly aligned engine could cost one of four space-worthy shuttles and the world's first and only long-term space station. Docking was over with soon, and was followed by the cosmonauts of Mir greeting the astronauts of Atlantis. Gifts of flowers, candy and fruit were given by the Americans, who in return, following a Russian tradit .....

.... acid and nitric acid, and air current can send them thousands of kilometres from the source.When the acids fall to the earth in any form it will have large impact on the growth or the preservation of certain wildlife. NO DEFENCE Areas in Ontario mainly southern regions that are near the Great Lakes, such substances as limestone or other known antacids can neutralize acids entering the body of water thereby protecting it. However, large areas of Ontario that are near the Pre©Cambrian Shield, with quartzite or granite based geology and little top soil, there is not enough buffering capacity to neutralize eve .....

.... the "that" of anything and not the "why;" for example; We all know "that" fire is hot but do we know "why." We also know "that" water is wet but "why" is it wet. These were questions that nobody obtained the answers to but Aristotle was determined to know, and having this type of knowledge would truly earn the title of PAGE 1 Wisdom. Now finding the knowledge and answers would be very difficult but Aristotle believed what better way to obtain this then through the use of science. He knew that everything in science deals with learning using more than just senses. There are always deeper meanings and definitions when pertaining to science. In .....

.... become less frequent with increasing age and are relatively uncommon after the age of 50. After interviewing my grandmother, who is a special case Migraine sufferer, she told me that her Migraines began when she was seven. Often in school she would have the classic migraine symptoms- she would see only half of her teacher and bright lights and flashes up to 20 minutes before her Migraine began. These symptoms are called auras and once they are gone the Migraine begins. The Migraine itself can lead to vomiting, slurred speech, makes the sufferer sensitive to light and worsens when there is a lot of noise. The mechanism is not complete .....

.... the life blood of the insurance industry. By not providing coverage for the billion dollar industry of alternative treatments, insurance companies are keeping the cost of the premiums down but at the same time not allowing their customers to use complementary treatments such as chiropractic to prevent or cure illness. The more rigid and restrictive the policy provisos, the more assurance for the companies that they will maximize their bottom lines. Therefore, patients of alternative therapies as well as doctors must show that such unconventional treatment provides relief and prevention of illness. “The total projected out-of- po .....

.... to mine it at a cheap cost. Chapter 2 Mining When uranium is extracted, pitchblende is broken up and mixed with sulfuric and nitric acids. It then dissolves into uranyl sulfate. With the addition of sodium hydroxide, uranium is precipitated as sodium diuranate which is known as the yellow oxide of uranium. To get uranium from carnotite, the ore must be finely ground and treated with a hot solution of caustic and potash to dissolve out the uranium, radium, and vanadium. And after the sandy matrix is washed away, the solution is treated with sulfuric acid and barium chloride. A caustic alkali solution is then added to the remaining clear .....

.... is caused by non-uniform temperature in a fluid and density differences. This continuous convection is the cause of plate movement. Each complete cycle, called a convection cell, drives the plate in the direction of the cell. How does a ‘solid’ mantle move? The mantle may be solid but, as with most solids, it will deform if long-term stress is applied. Presently, there are more than fourteen plates in the Earth’s crust. Upwelling hot magma flows out from mid-ocean ridges and then cools down when exposed to the cooled environment outside; the layer of cooled magma forms the lithosphere. When magma flows out from the ridges, the .....
