.... will be less likely to detect leakage ( 1). Leakage is when chemicals like leachates and other harmful materials that result from decomposing trash begin to leak out of the . When are located near bodies of water and are not properly maintained, chemicals and other materials can leak out and will go into the water which will be extremely hard to clean but will be hard for the EPA to detect. Doing this will allow the companies to save money because they will not have to barrel the leachates and pay to have them properly disposed of or stored ( 1). There are many things deposited in . Garbage, rubbish, ashes, large wastes, dead animals, sewage-treatment s .....

.... X and Y chromosomes. "What we're trying to decide now is whether to isolate probes for the other chromosomes, or whether we should utilize the eight we have," he says. Dr. Willard is currently negotiating with an American company to develop prenatal diagnostic tests, which, because the current tests are time consuming and technically difficult to do, are restricted to women over 35 and those who have a family history of chromosomal abnormalities. Prenatal tests using Willard's probes would be much simpler and faster to perform and could be available to all pregnant women who wish to take advantage of the technology. Current prenatal testing involves gr .....

.... chains, linked together by bonds between the bases of one chain and those of the other. An A is always bonded to a T, and every G is paired with a C; the result is that the sequence of bases in the two strands is complementary. The arrangement of the bases determines the genetic code of an organism. This code directs the synthesis of proteins at the cellular level. It is written in units called codons, each of which specifies a particular amino acid. (Proteins are composed of amino acids.) A codon consists of a sequence of three bases--for example, GAG or TCA. The four bases can be assembled into 64 possible codons. Because proteins are built from only 20 a .....

.... siderite, and bog iron (Encarta, 1996). Even though iron is tough and hard it is still easy to work. Iron is a active metal and will combine with halogens, carbon, etc. It has an atomic weight 55.847, it's atomic number is 26, it's specific gravity is 7.86, it's melting point is 1535 degrees Celsius, and it's boiling point is 3000 degrees Celsius. It burns in oxygen forming ferrous oxide. When exposed to moist air, iron becomes corroded, forming a reddish - brown, flaky, hydrated ferric oxide, commonly known as rust. (Encarta, 1996) Iron is formed in shallow seas. It comes out of the water and collects on the sea floor. This creates an underwate .....

.... momentum, which says the total momentum of an isolated system is the table and the balls, and the law then implies that the total momentum of the balls just before they collide is the total momentum just after the collision. Therefore if the masses of two colliding objects are known, the velocity and the velocity of the other before the collision, you can calculate the final velocity of this second object after it has collided. To obtain an exact answer however, we must find out what type of collision takes place, whether it is elastic or not elastic. The type of collision is characterized by what is called the coefficient of restitution. Thi .....

.... part to the low latitudes. It is located at south of Siberia and the north of the tropical Pacific. At this distinctive location, the country is affected by the alternate seasonal expansion and contraction of the polar continental highs and tropical maritime air masses, along with the seasonal shifts of the overhead sun. These changes in the pressure systems over Asia generate the unique Asian monsoon circulation which prevails over China throughout the year. Surface Pressure Field and Winds: For any fluid to initiate movements, pressure gradient must exists. Therefore, for a close understanding of the circulation system that operates over China, we should s .....

.... Saskatchewan, where some very striking examples of streamlining occur, was the type region for the development of the new theory [Shaw et al., 1984]. The sheet flood flows proposed for this area by Shaw et al were about 150 km wide, and the total volume of the meltwater reservoir was estimated as about 84,000 km3. The subglacial flood hypothesis for drumlin origin has been applied to drumlins in New York, southern Ontario, the northeast shore of Georgian Bay in Ontario, and to the interpretation of hummocky terrain in southern Alberta, and other areas, by various workers. Shaw suggested as many as 10 meltwater discharges, similar to those which caused the Li .....

.... snowy winter day. It felt like we only had two seasons all year either summer or winter. When we stepped out of the car we could see and hear birds singing. We could also smell, hear, and see the beautiful trees swaying in the gentle breeze. Pictures of a robin and a cardinal that we saw while stepping out of the car. We all got our gear out of the car and walked over to the trails. We had to decide what trail to take. We had three choices the first trail was half a mile long, the second trail was two miles long, and the third trail was four miles long. Since it was such a beautiful day we all decided to take the third trail that was fo .....
