.... walked on two legs, and it had two very short arms. The Tyrannosaurus was one of the most feared dinosaurs. The word Tyrannosaurus means “tyrant reptile�. Since the Tyrannosaurus Rex was a meat-eater, its teeth were shaped in zig-zag form which allowed it to cut through meat like a steak knife (Benton 161). It mainly relied on its strength when catching prey. Because it could not swim, many of its prey would run for shelter into water. Also, the Tyrannosaurus Rex was able to take big breaths due to lots of lung capacity, but it tired easily and could not put up much of a chase when its prey ran. (Monatersky 287). The Tyranno .....

.... to form a theory about planetary motion. The three most popular instruments which used were quadrant, armilla, and triquetrum. All furnish some measure of the position of the heavenly body. It took an endless amount of mathematical calculations to come up with the Copernicus' theory. He had to find out how fast the Earth spins around the Sun, and how far the Sun is. He also had to calculate the length of the orbit of the Earth. People use math in every walk of life. In our days everything is related to math, and Copernicus used his knowledge of mathematics to provide the human kind with an important discovery. Only a small amount of peo .....

.... research tool and a heuristic device in the sociology classroom. Three specific questions guide the discussion: 1) Why should sociologists concern themselves with the Internet?; 2) What are the various Internet technologies available to sociologists?, and; 3) How can faculty begin to integrate these technologies into their classrooms and research. Key words: teaching sociology, information technology, on-line teaching Introduction Information technology is quickly becoming the hub of efforts within the higher education community.

A panic attack is characterized by unpredictable attacks of severe anxiety with symptoms not related to any particular situation. (Hale, 1886). The person experiencing the attack may not be aware of the cause.

.... curved edges or too many curves look artificial. Choose plants for the pond and its surroundings that make the pond look genuine. Plants at the water's edge are usually different from those found on the surroundings higher ground. Especially reminiscent of natural ponds are large plant's that leaves 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 pref .....

.... and nitrogen oxides can be transformed into sulphuric 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 eno .....

.... are in. Thus, the brightest star in the Big Dipper (part of the constellation Ursa Major) is called alpha Ursa Majoris. Polaris, in the Little Dipper (Ursa Minor), is gamma (designated by the Greek lower-case letter gamma) Ursa Minoris, and Betelgeuse, in Orion, is gamma Orionis. VARIABLE STARS (those which periodically change in brightness) have lettered names, such as RR Lyrae in the constellation Lyra. Fainter stars are known by their numbers in a catalog; HD 12938 is the 12,938th star in the Henry Draper Catalogue. CHARACTERISTICS OF STARS Each star in the universe has its own position, motion, size, mass, chemical composition, and temperat .....
