.... the red. That is it's wavelength was longer than that of the light emitted from the corresponding atoms in the lab. Furthermore he found that the farther away the galaxy was the more it was shifted toward the red end of the spectrum. Hubble attributed this shift to the doppler effect. Hubble saw this and concluded that all galaxies are rushing away from us and the universe is expanding as a whole. Modern equipment has observed and verified this so-called Hubble expansion exists throughout the observable universe. This shows three important things. First there is no significance to the fact that earth seems to be the center of the universal expansion. In any ....

.... atmosphere of is quite different from that of Earth. It is composed primarily of carbon dioxide with small amounts of other gases. The six most common components of the atmosphere are Carbon Dioxide at 95.32%; Nitrogen at 2.7%; Argon at 1.6%; Oxygen 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 ....

.... deforestation can have on the environment and society. In this eassy I will point out these implication and the causes and disadvantages of deforestation and prove that it is wrong to cut down forests. Deforestation is the large-scale removal of forests. Why does deforestation occur? There are a many answers to that question but the main ones are: Ø For agricultural purposes eg space for building. (overpopulation) Trees are logged for the purpose of space. In this day and age the human race is multiplying and therefore we require more space to expand cites and build more houses. To do this world government cut down any forests in their way. Ø Industrial commerc ....

.... people never thought it would be as big as it is today. The Internet is an easy to use technology that can do just about anything. But what people don’t understand is that the Internet is not all good. Much of the information posted on sites on the Internet is merely opinions, not factual information. When people look at this information, it looks and seems like trustful information, but most of the time, it is not. Although the Internet is a relatively new technology, television has been around for about fifty years. There are many problems with television though, mainly with the content of the shows. Many of the shows on television portray violence, dru ....

.... most scientists now agree that almost all sightings and stories of extra terrestrials are not authentic. The United States government has records of thousands of UFO sightings since 1948, including photos of alleged UFOs and interviews with people who claim to have seen them. Since UFOs were considered a potential security risk, the report on these sightings was originally classified as secret. (Craig, 917) When the report was later declassified it showed that 90 percent of all UFO sightings could be easily explained. Most of the sightings turned out to be celestial objects, such as stars or bright planets like Venus, or atmospheric events such as auroras or meteor ....

.... together and the molecules would heat up, reacting with each other and giving off special scents. As you will see, it took a lot of researching to come up with the correct answer and see if my hypothesis was correct. I first had to research all of my chemicals and note their specific contributions to the experiment. The chemicals included vinegar, ethyl alcohol, sulfuric acid, salicylic acid, and methyl alcohol. RESEARCH OF THE PROBLEM To start my project, I researched vinegar. Vinegar is a sour liquid with a pungent odor, containing acetic acid, and is made by fermenting dilute alcoholic liquids such as cider, wine, or other fruit juice. Vinegar is used as a condiment, ....

.... appeal to customers. Psychological tests help people choose careers. Employers use tests as tools to help decide whether or not a person is fitted for a certain job. Psychologists help people with emotional problems to understand the basis of their difficulties. This understanding often brings a solution to the problems. A psychologist's specialty and place of employment determines their working conditions. Clinical, school, and counseling psychologists in private practice have pleasant, comfortable offices and set their own hours. However, they often must offer evening hours to accommodate their clients. Those employed in hospitals, nursing homes, and other health faciliti ....

.... and powerful lightning bolts arced through the skies, lighting up the desolate landscape.  Given enough time, cosmic rays, and lightning bolts, a "primordial soup" gradually formed which contained amino acids.  These in turn got hooked together to form simple proteins, the "building blocks" of life.  At some point these proteins happened to get connected in just the right way, and a threshold was crossed:  the proteins started reproducing themselves, and simple life was "born". During uncounted eons, this simple life gradually became more and more complex as chance modifications of the original proteins combined with external conditions of moisture, temperature, ....
