.... grown for use as drug, while hemp is very low in THC and is not considered a drug.) Plant also produces 40% more oxygen than any other plant. Marijuana is the most widespread drug in the world, if only hemp could be the most widespread crop in the world. Marijuana is a plant, with the botanical name of . Marijuana is a weed that grows wild and is cultivated in many parts of the world. Containing 419 chemicals, this plant has the ability to intoxicate its users, primarily because of the psychoactive mind altering ingredients called Delta - 9 - Tetrahydrocannabinol, or THC. It is the THC content found at various concentration in different parts of the plant .....

.... 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 you’ve never misused antibiotics, you could still become infected by bacterium most drugs won’t kill. For each drug, there are germs genetically programmed to survive .....

.... feet, an estimated mass of 100 million tons, and a volume of 2.9 billion cubic feet. In total acreage, it is equal to 16,000 baseball diamonds [Miller 526]. By the year 2005, when the landfill is projected to close, its elevation will reach 505 feet above sea level, making it the highest point along the Eastern Seaboard, from Florida to Maine. At that height, the mound will constitute a hazard to air traffic at Newark airport [Rathje 3-4]. The area now encompassed by the Fresh Kills (Kills is from the Dutch word for creek) Landfill was originally a tidal marsh. In 1948, New York City planner Robert Moses developed a highly praised project to deposit municipal .....

.... a basic understanding of what it is. What we call light, the intangible, powerful force that powers our world, is somewhat hard to define in real terms. It shares properties with both particles and waves. It follows the same rules as a wave does--it moves in a regular fashion, in a perfect sine wave at a certain frequency. It travels in a straight line, and is subject to refraction. All of these characteristics are found in waves of any type, from radio frequency waves, up to Gamma and X- rays. Light, however, also exhibits qualities characteristic of particles such as neutrons and protons. A photon, or quanta, is the "packet" of energy that is sent in a lig .....

.... which contain an average of several thousand genes each. During certain phases of the cell's life cycle, the chromosomes are stretched out into long, thin strands, and they are tangled together into a network called chromatin. In addition to genes, chromosomes contain proteins, some of which cover the genes that are not "turned on" at the particular time. The original genetic information, stored in a coded form DNA, is carried out of the nucleus by RNA and then translated into proteins by ribosomes. 70% of oncogenes are located in the weak points of the chromosomes-hereditary regions where the DNA molecule may break or its portions may be rearranged into new .....

.... were Astrologers. In ancient times, the Greeks and Romans based their system of gods on what they believed was up in the sky. Zeus and the other gods and goddesses were based on the planets that were visible to the people of that time. Astrology was also popular in Babylon, Egypt, the Middle East, and China. Modern Astrology has changed as new planets have been discovered. Astrology is about the interaction between the planets, including the Sun and the Moon, and the Star Signs. It studies the mathmatical cycles on which these interactions are based. In some ways, the forces between the planets involved in Astrology can be simplified into one word : gravity. Th .....

.... a lot on the earth because gravity cannot keep helium from escaping to space. Helium is found mostly in stars, where it goes through nuclear fusion with hydrogen. Most Helium comes from natural gas taps in North America. It is used in balloons and divers use it with oxygen to breath easier and to not get sick or dizzy. Neon is an element that is lighter than air. The element is found most common in the atmosphere of the earth. It is also found in the earth¹ s crust. It was discovered in 1898 by Sir Walter Ramsey and Morris W. Travers. Its uses include electric signs,lamps,and lasers. Argon is the most abundant and most used noble on earth. It was di .....

.... follows: American Arthur L. Shcawlow, the Russians Alexander M. Prokhorov and Nikolai G. Basov, and the American Gordon Gould. But the first laser was constructed in 1960 by American physicist T.H. Maiman and it is still one of the most powerful available. This laser used a ruby rod for its active medium, which is its way of producing light. Ali Javan then created the first gas laser later in 1960. Three separate teams of American scientists operated the first semiconductor laser in 1962. Then in 1966, the American physicist Peter Sorokin built the first dye laser. To begin with, I will explain the definition of a laser: It is a device that produces a very na .....
