Orion Nebula

... has been estimated that this nebula is only 1,500 light years away. In addition, the is a relatively young star cluster, with an approximate age of less than one million years. It has even been speculated that some of the younger stars within the cluster are only 300,000 years old. The is an emission nebula because of the O-type and B-type stars contained within it. These high-temperature stars emit ultraviolet (UV) light that ionizes the surrounding hydrogen atoms into protons (H+) and electrons (e-). When the protons and electrons reco ...

Mammals

... as in sea cows. All mammals, except the egg-laying monotremes, produce live young that undergo the early stages of development within the body cavity of the mother. Some mammals are helpless at birth, others are able to walk and even run immediately, and may be born fully furred and with their eyes and earsopen. The largest mammal, the blue whale, Often exceeds 30 m (100 ft) in length, and the smallest shrews, mice, and bats are often less than 5 cm (less than 2 in) in length. In many mammals the color of the skin or fur blends with t ...

Solar Energy: An Alternative Energy

... Solar energy is the visible energy produced in the sun as a result of a constant nuclear fusion reaction that is taking place. The amount of energy at the solar constant, which is at outer edge of the earth's atmosphere, is two calories per minute per cm squared. A calorie is the amount of energy needed to raise one gram of water one degree Celsius. If we could efficiently harness the energy bombarding the earth for twenty-four hours we could power New York for a year. Unfortunately the photovoltaic cells that change the energy into elect ...

Growth Rate Of A Seed

... will grow more then the seed that is kept in the dark. Experimental design: I took the four seeds and divided theme into groups of two. I placed theme inside a paper towel which was inside a cup. I water both of the cups and placed one in the closet, where it was dark. The other cup I placed on the ledge, where there was a large amount of light at all times. Each day I provided the seed with the equal amount of water. In this experiment I had one control which was the plant in the dark. Results and conclusion: My hypothesis was correct. As yo ...

Flesh-eating Bacteria

... right now, medical researchers are testing antibiotics that may have chemicals to disable the resistance of this organism. But while research continues, it is vital to be aware of how these deadly germs spread and what we can do to prevent them. Long before humans discovered antibiotics, they existed in nature. So naturally, after penicillin was introduced, some germs were already naturally resistant to the drug. As we used more and more of the antibiotics, we incidentally caused drug-resistant germs to progress. So, even if you̵ ...

Cancer 3

... used to combat osteoarthritis, a condition that effects the joints and its surroundings. For a better understanding to how glucosamine works, this paper will include what glucosamine sulfate is, how is works, and what it works on (osteoarthritis). Also included is an in-depth look at osteoarthritis, or degenerative joint disease (DJD), which is the most common type of arthritis, affecting over 16 million people in the United States today (1). Arthritis refers to inflammation or swelling of the joints. The most common form of arthritis is oste ...

Death Of A Planet

... of two or more elements, that contain only carbon and hydrogen (2 factsheet, OMS-5). Hydrocarbons are released when fuel in the engine burns partially. When hydrocarbons come in contact with sunlight they form ground level ozone. Ground level ozone is a major ingredient in the formation of smog. Ground level ozone is responsible for irritating eyes, damaging lungs, and it complicating respiratory problems. Hydrocarbons aren't the only pollutants released through car exhaust. Two more pollutants released through car exhaust are ca ...

Early Synthetic Polymers

... later. These are the cellulose derivatives. They are also derivatives of a natural polymer, cellulose. They hold a special place in polymer history, because their invention in a lot of ways was the beginning of an explosion in the invention of synthetic polymers which continues to this day. Cellulose derivatives are forms of cellulose, a polymer found in wood, cotton, and paper, which have been chemically altered. Scientists first started to make them in the second half of the nineteenth century, long before we really even knew what a poly ...

Alternative Energy Sources

... for several years. It is imperative that these alternatives be implemented long before the current supply is depleted. Without question, the world's energy demand has increased due directly to the fact that the population continues to rise. What this translates to in correlating statistics is that energy demands throughout the past half century have tripled, the global economy has quintupled and the world population increased twofold (Anonymous em_txt4.html).
