Religion & Evolution
.... that lies deep within ourselves. As for myself, I cannot believe in a being which created a universe and a multitude of worlds in a rather short period of time then deigns to lower itself into becoming a puppet-master and "pulling the strings" of the Earth and all of the people therein.
Since this paper touches upon many scientific terms, I feel that in order for the reader to correctly grasp the content I must first define three words: Theory, Law, and Hypothesis. The definitions will allow for a gre .....

Solar Cells
.... with the orbital radius. When atoms bond together to form a solid, the electron energy levels merge into bands.
In electrical conductors, these bands are continuous but in insulators and semiconductors there is an "energy gap", in which no electron orbits can exist, between the inner valence band and outer conduction band [Book 1]. Valence electrons help to bind together the atoms in a solid by orbiting 2 adjacent nucleii, while conduction electrons, being less closely bound to the nucleii, are free .....

Cloud Formations
.... that are not attached to each other, and is usually white with no shading. Cirrocumulus clouds appear like very small round balls or flakes. The cirrocumulus clouds sometimes form a pattern of a buttermilk sky. The cirrostratus clouds sometimes form tangled webs or thin whitish sheets. A large ring or halo is sometimes seen around the sun or moon when the cirrostratus covers the sky.
The middle layer of clouds range in altitude from 6,500 to 23,000 feet. The altocumulus, altostratus, and nimbostrat .....

Darwin’s Finches
.... example of allopatric speciation is the differences between the common giraffe (Giraffa camelopardalis), and the reticulated giraffe (Giraffa cameloparadalis reticula). These two subspecies have formed on different sides of the Tana River in Kenya. They are phenotypically distinct, and can only produce fertile offspring in zoos.
Sympatric speciation occurs when two segments of the same species occupy a geographical area without interbreeding. Each new species, or subspecies, adapt to a specific envir .....

Possibility Of Terraforming One Of Earth's Neighboring Planets
.... and celestial ether that is conducive to human respiration. There are two planets from which to choose: Mars and Venus.
Martyn J. Fogg authored what is regarded as a textbook of the future called Terraforming: Engineering Planetary Environments. I have chosen Fogg's book as my second primary source because it is the only book of its kind that addresses the question of terraforming in a non- science fiction context.
The successful terraformation of a planet requires the synthetic development of a b .....

Essay On Global Warming
.... human-induced gases include carbon dioxide, methane, nitrous oxide, and ozone depleting substances such as CFCs, also known as Chlorofluorocarbons, hydrofluorocarbons, and perfluorocarbons. These gases are generated a number of human activities such as fossil fuel combustion, waste disposal in landfills, the use of a refrigerator, numerous agricultural and industrial activities, and the cutting down of numerous forests.
These human practices have already changed the chemical make up of the atmosp .....

Sedimentary Rocks
.... carry some chemical sediment, and most chemical sedimentary rocks also contain some loose sediment material.
All sedimentary rocks are in general characterized by the parallel arrangement of their mineral layers or beds, which are distinguished from each other by differences in thickness, the size of the grains, or color.
All rock disintegrate slowly as a result of mechanical weathering and chemical weathering. Mechanical weathering is the breakdown of rock into particles without producing chan .....

Polymers

New polymers are being created with more strength and flexibility by combing two chemically different polymers and producing a block copolymer. Combinations of block copolymers and composites and intended for use in booster rockets and in materials of Earth-orbiting installations.
Most common pol .....

Cellular Diffusion
.... transport, all of which involve only small simple molecules.
Diffusion is the movement of a substance from a region of high concentration, to a region of low concentration of that substance. In other words, a movement down the concentration gradient. Osmosis is very similar to diffusion, however it involves the concentration of water. Osmosis, like diffusion, is a passive process, and does not require energy to occur. Active transport does require energy though, as it involves movement up the concent .....

How Toxic Waste Affects Canada’s Natural Environment
.... which are dumped in improper sites, can seep into underground water supplies and contaminate huge areas. If the land that is intoxicated supports plant life, most of the plants and trees will die off. If humans occupy the area, it could cause serious illness or death. For example, an area by Niagara Falls (US side) was used during the 1930s by a chemical company to dump its waste. Most of them were hazardous, and the containers that held the chemicals later (after the company had gone out of business) be .....

The Theory Of Evolution
.... joined, a membrane grew around the proteins, and the first complete cell was formed (Dawkins 16). According to evolution, this process was the beginning of life.
But, there are minimal chances that this organic soup would form. Consider the experiment of Stanley Miller. In 1953, Stanley Miller passed an electric spark through an atmosphere of hydrogen, methane, ammonia, and water vapor; an atmosphere similar to the so-called "primitive atmosphere." But, this produced only 4 out of the 20 amino acids ess .....

Glass
.... The properties of glass vary and regulate by modifying the composition, production techniques or both. Glass represents a combination of properties that can not be separated, such as mechanical, chemical, optical and thermal properties. Glass is an intriguing substance in the way that the moment you change the percentage of one of its components, the glass itself is different. (Education Dep. Properties: Chemical). Often, it can even be classified as a different type of glass. Commercial glasses ar .....

Acid Rain
.... the rate of most of these reactions. Rainwater, snow, fog, and other forms of precipitation containing those mild solutions of sulfuric and nitric acids fall to the earth as acid rain.
Water moves through every living plant and animal, streams, lakes, and oceans in the hydrologic cycle. In that cycle, water evaporates from the land and sea into the atmosphere. Water in the atmosphere then condenses to form clouds. Clouds release the water back to the earth as rain, snow, or fog. When water droplet .....

Black Smokers

Up until recently, smokers have only been observed by videotape and "deep-diving submersibles". Last summer a team from the University of Washington and the American Museum of Natural History accomplished the task of bringing four "black smokers" to the surface. The method that the team used for retrieval was quite interesting. The team followed a "loggers technique" for detaching the smoke .....

Clean Coal Technologies

It's the most plentiful type of coal in the States, and is mainly found in the eastern and middle part of the North American continent. Bituminous coal is primary used to generate electricity, and has a carbon content of 45 to 86 percent and a heat value of 10,500 to 15,000 Btu's. Sub-b .....
