    Skin Cancer Skin Cancer About a million americans will develop skin cancer this year. Skin cancer is the most prevalent of all cancers, and it's increasingly on the rise. There are millions of tiny cells that make up the human body. There are different kinds of cells, but they all make new cells by a process that involves dividing in half. This is how old cells are replaced with strong new cells. When a cells divides and doesn't do the job that it was intended to do for the body, and then it continues to divide and makes more of these useless cells, and these cells continue to collect, it is called a tumor. There are two types of tumors: benign and malignant. The cells in a benign tumor can ...

    Skin Cancer Every hour one American is killed by skin cancer and every thirty seconds one American gets skin cancer. Cancer is a deadly disease that alters the DNA of a skin cell and causes it to reproduce at a rapid pace. This overproduction of cells can be harmful and in many cases deadly. Out of these cancers the most common is Basal cell carcinoma. Many steps have been made in the treatment of Basal Cell Carcinoma, some have been very successful and some not. The cells that have the altered DNA are called malignant or cancerous cells. These cells are found in the outer layers of the skin. The skin's main job is to protect the body from infections and to insulate the body to keep it at th ...

    "Skin Cancer" ------------------ Gone are the days when people sent children outside to play to get a little color in their cheeks. They know too much about the dangers of unprotected sun exposure and the threat of skin cancer. Or do they? Despite the fact that 58% of parents remembered hearing about the importance of protecting their children from the sun, children are still playing in the sun without sunscreen or protective clothing (3., p 1). Sunburn is the most preventable risk factor of skin cancer. Skin type and family history cannot be changed. Protection from the sun and education of the potential hazards of the sun need serious attention. The American Cancer Society estimates that o ...

  • Aids - 1,410 words
    Aids Aids by sean ross How is HIV Diagnosed? You can get tested for HIV in a number of locations -- including public clinics, AIDS organizations, physicians' offices, and hospitals. Many locations give the test for free. You can choose between anonymous tests, in which you do not give your name to the HealthCare provider, or confidential tests, in which you do give your name. Test sites should provide trained counselors who can offer you support and guidance, no matter what the test result.(Balch-97) An HIV test looks for the antibodies your immune system creates in response to the virus. These antibodies may not appear in your blood until three to six months after HIV infection. Therefore, ...

Ozone depletion is looked upon as a problem that up till now, we can not fix. Air pollution has caused this hole in the ozone layer. The ozone layer absorbs 99% of the sun's harmful energy. It prevents ultraviolet radiation from reaching the Earth's surface and the troposphere. It protects humans from sunburn, skin and eye cancer, and cataracts. It also prevents much of the oxygen in the troposphere from being converted to ozone (gas). In the mid-seventies chemists F. Sherwood Rowland and Mario J. Malian discovered CFC's were creating a global chemical time bomb by ...

    Australia Studies Since 1988 Australia has changed quite a bit, one would hope it was for the better and it looks that way. As Australians we have become more health conscious and we have stopped being ashamed of our multiculturalism. There are three domains where change can be noticed the most. These are: Environment, Culture and Social systems. In each of these domains over the past twelve years Australia has become more diverse in culture, richer in Environment and more giving and learned in Social systems. ENVIRONMENT From the mid twentieth century Australia has been a nation of people who flock to the beach on the weekends as a ritual. Everyone eagerly awaited the arrival of a radio sta ...

  • Cancer In American - 331 words
    Cancer in American In modern society cancer is the disease most feared by the majority of people throughout the world, supplanting the "white death," or tuberculosis, of the last century; the "black death," or bubonic plague, of the Middle Ages; and the leprosy of biblical times. Cancer has been known and described throughout history, although its greater prevalence today is undoubtedly due to the conquest by medical science of most infectious diseases and to the increased life span of humans. The study of cancer is known as the field of ONCOLOGY. In the mid-1980s nearly 6 million new cancer cases and more than 4 million deaths from cancer were being reported world-wide each year. The most c ...

  • Chlorofluorocarbons Cfcs - 701 words
    Chlorofluorocarbons (CFCs) CFCs are a family of man-made gases used for various industrial purposes. First developed in the 1920's in the United States, CFCs have been used in large quantaties since 1950. The industrialized countries can account for over 80% of CFCs use. CFC-11 is used primarily as a propellant in aerosol cans, although its use has been phased out it is still used in the production of plastic foams. CFC-12 is used in foam production as well as cooling coals of refrigerators and air conditioners. HCFC-22 was recently introduced as a replacement for CFC-12 because of its shorter life in the atmosphere, and thus is less of an ozone depleting drug. CFC-113, methyl chloroform, an ...

She had other ideas, and struggled against him like fury. The idea of her brothers standing watching made her fight all the harder, but at last her shoulders were pinned to the hay-covered floor." Great," said the twins in unison, "now kiss her." But Beatrice wouldn't co-operate in that either, and renewed the battle with even greater fury. Thus ended the first romance. The first job was at the Bank of Commerce in Creston when Birney was 16, wages $15 a week. He was a "promising young man" when the bank transferred him ...

It is a necessity to own or to have access to a car in order to keep up with all of the competition of the business world, and also one's social demands. Most people would not be able to travel around a country or the world without this incredible machine, for it provides freedom and mobility, even for people who do not own a car. Unfortunately, the car has a very destructive nature. Automobiles make a major contribution to air and noise pollution, the depletion of fossil fuels, and the abnormalities in children and adults due to lead poison ...

  • Electromagnetic Waves - 294 words
    Electromagnetic Waves I went to Hawaii on vacation to get a tan, but I got something else instead. Ultraviolet rays are stronger, and hotter near the equator. When I got home I got x-rays. I was sent for treatment with gamma rays. Wow! What a vacation. It was so hot that I had to jump into a pool just to cool off. Ultraviolet rays have wavelengths between 10nm and 430 nm. They also have a very high frequency of about 10,000,000,000,000,000 Hz.- 1,000,000,000,000,000,000 Hz. Photon energy emissions are also very high. I think that overexposure to ultraviolet waves caused my sunburn and skin cancer. I had broken my leg by falling in-between the plane and the causeway while getting off the plan ...

  • Gene Therapy Hemophilia - 1,090 words
    Gene Therapy- Hemophilia Genetic Therapy that focuses on hemophilia Gene therapy is reinserting certain genes that helps deal with genetic diseases. There are three basic forms of this gene therapy. The first is Gene Inactivation Therapy in which the transferred gene neutralizes the proteins and evens out the amount or rids of the defective proteins. Another type is Gene Augmentation Therapy where the original form of the gene or the normal form of the gene is inserted into one of the cells chromosomes. This procedure is used normally when a gene with little activity or a deleted gene is the cause for the genetic disease. The third type of gene therapy is Gene Replacement Therapy. This form ...

    Global Warming (After a lot of reading and hunting around on the net, I found a great deal of information on this topic. I had never really researched on it before so wanted to make sure that calculations agreed from report to report. Most of them did so I will base my answer on these different reports. This subject is extremely interesting, scary and a bit of a shock as to how much we have abused and taken advantage of this Earth. Though progress as far as technology has been something we make use of and enjoy, we are paying for it in ways I never thought of before this subject came up in this class! Please forgive my ignorance. I am troubled that my children and their children will suffer ...

  • Man And The Ozone - 1,120 words
    Man And The Ozone Man and the Ozone Ozone is perhaps one of the singularly most important molecules there is. No, not because man came from ozone, but because it forms a protective layer above the earth in it's stratosphere which allowed for the growth of life upon land. Before we had an ozone layer, the rays of the sun struck the earth unimpeded, barraging it with the deadly ultraviolet radiation which prohibited any chance of life on earth. However, there was life in the oceans, plant life in particular. This plant life may seem unimportant, especially since it is algae that is being given the spotlight. The algae in the ocean produces oxygen gas (O2), which would rise through the water an ...

  • Ozone - 983 words
    Ozone annon Ozone is an important molecule in maintaining the homeostasis in the environment. Ozone, the molecule O3, makes a layer in the stratosphere, situated 10 to 15 kilometers from the earth's surface. The dioxide molecule, O2 and Oxygen atom O, collide with each other result in the formation of Ozone, O3. In this reaction, the molecule O3 contains an excess of energy. Once the molecule is formed, it is not stable enough to last long. The energy-rich O3 molecules discards the excess energy by colliding with another atom or molecule and transferring the energy in the form of heat. In the results of the decomposition of ozone into O2 and O in the ozone layer, solar radiation is absorbed. ...

  • Ozone Depletion Is An Environmental Problem That Many People Do Not Take As Seriously As They Should The Ozone Layer Prot - 1,074 words
    Ozone depletion is an environmental problem that many people do not take as seriously as they should. "The ozone layer protects animal and plant life from the sun's harmful radiation. The depletion of the ozone layer will allow ultraviolet rays to, over time, lead to higher skin cancer rates, eye cataracts, and crop damage." At ground level, ozone, a form of oxygen, is poisonous to humans and other organisms. It causes respiratory problems and damages plants. The greatest concentration of ozone is located in a layer of air called the stratosphere, some 10 to 30 miles above the Earth's surface. About 90% of the Earth's protective ozone layer resides in this level. "The molecule, ozone, is pro ...
