.... There is also the Toxic Pits cleanup act of 1984. This act states that there is to be no discharge of hazardous wastes within an half a mile of a potential drinking water source. This is something being done, but water does travel and seep through ground so what is this act really doing. The clean water act is designed to protect ground water indirectly by protecting the quality of surface water. The standards for the surface water require sewage treatment , and discharge of industrial and municiple waste water into surface water. There is also the Comprehensive Environmental Re .....

.... the heart beat and breathing rate. Cigarette smoke also contains carbon monoxide, the same poisonous gases released from a car exhaust pipe. Carbon monoxide is a colorless and odorless, highly toxic gas that reduces the amount of oxygen that the blood can carry. Combined with the effects produced by the nicotine, it creates an imbalance in the demand for oxygen by the cells and the amount of oxygen the blood is able to supply. Tar is another chemical produced from cigarette smoke. Tar contains at least 30 cancer causing irritants. Tar is a mixture of several substances t .....

.... are bigger than and also much less acrobatic. However, they are still good climbers. While orangutans spend most of their life in trees, where they use their long arms and dexterous hands and feet to grasp branches and vines, chimpanzees frequently come to the ground to feed. Gorillas are primarily terrestrial, but even fully grown adult males have been observed clambering among tree branches more than 15 m (49 ft) high. Chimpanzees and gorillas—the apes that spend the most time on the ground—normally walk on all fours, clenching their hands so that their knuckles take their w .....

.... a mouthpiece of a telephone after a conversation. DNA is everywhere in a persons body, and can not be replicated. It is unique to every person, but all blood relatives have similar qualities that make them identifiable. (Joe Mickel and John F. Fischer, 1998) DNA stands for deoxyribonucleic acid, and it basically looks like a twisted ladder, or a double helix with rungs or base pairs. Guanine (G), Adenine (A), Thymine (T), and Cytosine (C) are the four bases that make up the base pairs. The bases don't just pair with any other bases, there are certain predictable combinations: A with T a .....

.... in their jaw and dying even when the tumor was removed. He later found out that the patients were coming from areas highly infested with mosquitoes, so they figured that the mosquitoes were related. The mosquitoes were carrying a virus in the herpes family, which was later called Epstein-Barr virus. This virus was later revealed to be linked with mono. (6) Anyone can get mono but it is most common in teens and young adults, mostly high school and college students. Children who are infected with EBV when they are really young are able to manufacture antibodies against the virus. If a p .....

.... across the world are being destroyed everyday. These rainforests are being destroyed by human efforts which are centred around greed. Oil companines drilling for oil, logging companies, and fires are the leading causes in destroying the last Nigerian Rainforest. Rainforests cover only two percent of the entire earth’s surface.1 It is estimated that ninety-five percent of Nigeria’s rainforest has been destroyed. A Hong Kong company is logging out of Nigeria for the use of ply-wood, toothpicks, veneer, and chopsticks.2 People need to become more educated about the im .....

.... selected by forcing them to swim through a culture medium. - The egg and sperm are placed together in a suitable medium for fertilisation to occur in a culture dish. If fertilisation does not occur after 72 hours, the oocytes (incompletely developed eggs) and sperm are disposed of. The resulting embryos are observed for the next few days. - A small plastic tube is inserted through cervix to place embryos into the uterus. The patient is able to go home a few hours later with minimal discomfort. During the first two weeks after embryonic transfer, hormones (such as Progesterone or HCG .....

.... density, V for the velocity of the air passing over the wing, and S for the area of the wing when viewed from above or below. As the air flows over the wing producing lift, it grabs onto the wings surface and causes drag. Drag can be measured by the equation D=Cd 1/2 (pV2)S, much like the lift equation. The drag coeficent Cd is found, again, by determining the shape of the airfoil and then finding the angle of attack. Drag is less than lift up to a certain angle of attack. After that, the air encountering the surface of the wing is either pushed off or deflected in a way to cause tu .....

.... with 7 to 11 flagella. More than 30 proteins are contained within B. burgdorferi1. This bacteria uses white-footed mice, mosquitoes, and deer as their hosts. This disease does not discriminate between sex and age; male and female, as well as old and young are affected. It is widely distributed around the world in the temperate zones3. A person is infected when a black-legged tick imbeds itself into them while out in the open in wodded and forested areas. This usually occurs between the months of May and July. Tick abundance is associated with humidity, temperature, landsca .....

.... the topsoil to the groundwater, due to rainfall or irrigation, can result in a dramatic rise in groundwater pressure and watertable levels. The trees of the open forests are now replaced by shallow-rooted crops and pastures which absorb far less water than the native trees. Those trees had been massive water pumps, sucking up moisture from deep underground and putting it back into the atmosphere through the evaporation from their leaves. With those pumps gone, excess rainfall accumulates underground and watertables rise to the surface, bringing ancient sediments of salt with them, often in .....
