.... are harmful to our environment. Automobiles run on gasoline, which is a mixture derived from petroleum. Gasoline contains hundreds of different hydrocarbons, or compounds containing the chemical elements carbon and hydrogen(Gasoline). When the gas is burned in the engine of the car, several byproducts result. These exhausts include hydrocarbons and oxides of three elements: Carbon, nitrogen, and sulfur(Emissions). Tiny amounts of poisonous trace elements such as lead, cadmium, and nickel also are present. Everything contained in the exhaust affects the env .....

.... Mary Shelley’s “Frankenstein” serves as a bioethical exhortation for today’s technological advances in genetic cloning. Mary Shelly’s “Frankenstein” provides a clear distinction between the theoretical grandeur of man’s ability to scientifically author life and the stark reality, which it encompasses. Mary prophetically illustrates some of the potential hazards of breaking through the barrier that separates man from God (Bloom 611). Her insight allows the reader to trace these repercussions through Victor Frankenstein, the monster, and eventually societ .....

.... chemicals, it is first important to establish its potency prior to freezing. Accordingly, two test sets were created by the researcher. The purpose of the test was to determine how well the chemicals could break down household grease before and after the substances were frozen. The first test set would focus on unfrozen chemicals, while the second was set up for previously frozen chemicals. The Test: To start the experiment the researcher fried four pieces of bacon until there was enough grease in the skillet to perform the test. He then put a quarter .....

.... at 0.13%; Water at 0.03%; and Neon at 0.00025 %. Martian air contains only about 1/1,000 as much water as our air, but even this small amount can condense out, forming clouds that rise high in the atmosphere or swirl around the slopes of towering volcanoes. Local patches of early morning fog can form in valleys. At the Viking Lander 2 site, a thin layer of water frost covered the ground each winter. There is evidence that in the past a denser Martian atmosphere may have allowed water to flow on the planet. Physical features closely resembling shorelines, g .....

.... better healthcare, and more funding to school. Nuclear power is also a lot environment wise. Nuclear power requires a mere fraction of the space that is required to set up a solar, wind, or hydroelectric generating station which. This will allow more space for private landowners and will also keep land prices at a lower cost. Nuclear power is also a much cleaner operating type of fuel. The amount of waste produced is from a nuclear power plant is not even a fraction of the amount of sulfur, carbon monoxide, and nitrogen oxide produced by a coal plant. By buil .....

.... example, environmental reports indicated that almost half the trees in Germany’s Black Forest had been damaged by acid rain. This form of pollution has also particularly affected the northeastern United States and eastern Canada. Industrial emissions have been blamed as the major cause of acid rain. Because the chemical reactions involved in the production of acid rain in the atmosphere are complex and as yet little understood, industries have tended to challenge such assessments and to stress the need for further studies; and because of the cost of pollution red .....

.... collapses, very small particles (called neutrinos) escape into space. After the star becomes a very small sphere, it explodes like a giant nuclear bomb and becomes a billion times as bright as our own sun. All kinds of matter and radiation are blasted into space. This matter and radiation travels through space at nearly the speed of light (186,000 miles per second) Now, if one of these supernovae were to occur within about 130 light years of Earth, some scientists feel that life on earth would be drastically affected. Since a light year is the distance l .....

.... of these single strands of a DNA molecule, a mRNA molecule is built. This is accomplished by an enzyme which travels along a portion of DNA between two exons and attaches the opposing base pairs to the backbone of the mRNA (a structure composed of phosphates and ribose). The nitrogen bases of this new molecule are identical to that of the opposite side of the original DNA molecule except that the thymine has been replaced with uracil. The formation of this molecule allows for the construction of proteins in the ribosome without risking the DNA in the cytoplasm. The mRNA travels through the cell to a ribo .....
