The Cystic Fibrosis Gene Introduction: Cystic fibrosis is an inherited autosomal recessive disease that exerts its main effects on the digestive system and the lungs. This disease is the most common genetic disorder amongst Caucasians. Cystic fibrosis affects about one in 2,500 people, with one in twenty five being a heterozygote. With the use of antibiotics, the life span of a person afflicted with CF can be extended up to thirty years however, most die before the age of thirteen.1 Since so man

As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases.1 What causes the depletion of the ozone layer?

This drug can help to aid such notorious diseases as AIDS and glaucoma. The name of this drug is cannabis sativa, or its more well-known name, marijuana. Cannabis sativa should be legalized for its medicinal uses. This paper will state the different types of diseases that marijuana may be used for, the current steps towards

Furthermore, the deterioration of the ozone cause an increase of Ultraviolet (UV) radiation which can have a negative effect on human skin and eyes.

Birth Control The practice of birth control prevents conception, thus limiting reproduction. The term birth control, coined by Margaret SANGER in 1914, usually refers specifically to methods of contraception, including STERILIZATION. The terms family planning and planned parenthood have a broader application. METHODS OF BIRTH CONTROL Attempts to control fertility have been going on for thousands of years. References to preventing conception are found in the writings of priests, philosophers, and

It provides the air we breathe and regulates our global temperature. And it contains a special ingredient called ozone that filters deadly solar radiation. The gaseous area surrounding the planet is divided into several spherical strata separated by narrow transition zones which is the atmosphere. (Graedel

The greenhouse effect is an increase in the atmospheric temperature caused by increasing amounts of greenhouse gases. These gases act as a heat blanket insulating the Earth's surface absorbing and trapping heat radiation which normally escapes from the earth. They include carbon dioxide, water vapor, methane, nitrous oxide, CFC's, and other halocarbons. The earth's atmosphere goes through two processes constantly. Global cooling is the first process. This process uses the clouds which cover 60%

anthrax Anthrax (Bacillus anthracis) is an acute infectious disease caused by the spore-forming bacterium. The most common victims of anthrax are warm-blooded animals, but it can also infect humans. Anthrax spores can be produced in a powdery form for biological warfare. When inhaled by humans, these particles cause respiratory failure and death within a week. Because anthrax is considered to be a potential agent for use in biological warfare, the Department of Defense (DOD), in 1998, announced

At the same time this destroyed by various reactions with other components in the air.
