Canabis
Number of words: 617 - Number of pages: 3.... from the wishes of those in power. Alcohol prohibition struck directly at tens of millions of Americans of all ages, including many of societies most powerful members. Marijuana prohibition threatened far fewer Americans, and they had relatively little influence in the districts of power. Only the prohibition of marijuana, which some sixty million Americans have violated since 1965 has come close to approximating the prohibition experience, but marijuana smokers consist mostly of young and relatively powerless Americans (American Heritage, pg 47). Alcohol prohibition was repealed and marij .....

"Biodiversity"
Number of words: 505 - Number of pages: 2.... to this problem. An example of this is the
gold mining operation that we saw in the video. While mining, Mercury was
dripping into the water. The mercury then got into the fish and into the humans
who ate the fish.
Biodiversity promotes a healthy environment. Environments rich in
biodiversity are stronger and can with stand things such as drought, disease,
and other stresses that environments that lack it cannot. In the video, during
the drought, the side of the field with a more diverse environment held stern as
the other wilted away.
Areas that are very diverse are very important to .....

Cell Division
Number of words: 395 - Number of pages: 2.... prophase, the nuclear envelope fragments, and the microtubles attach to the kinetochores and overlap. In Metaphase, the chromosomes line up along the metaphase plate. The centromeres are all aligned and the sister chromatids straddle the metaphase plate. Anaphase beings when the sister chromatids are pulled away from each other. The chromosomess begin moving along the microtubles towards opposite ends of the cell, which is now in an oval shape. At telophase, the nonkinetochore microtubules elongate the cell even more, and daughter nuclei begin to form. Nuclear envelopes are reconstruc .....

Mitochondrion
Number of words: 215 - Number of pages: 1.... invaded primordial cells and evolved along with them. A
mitochondrian’s main purpose is to burn energy through a slow method of
combustion, which will consume as much air to burn as fire will, just to break
down nutrients into simpler substances. These simpler molecules then bond with
the atoms that will need the energy to function. Then, enzymes in the
mitochondrion break up the atoms and then recapture them again. This time, the
energy atoms will be bonded in a different molecule to form ATP, or adenosine
triphosphate. ATP has an adenosine core and three phosphates attached to it,
he .....

Hydrogen 2
Number of words: 1155 - Number of pages: 5.... are possible with more research. Another method of producing hydrogen is through chemical means. It is a scientific fact that every metal that is less noble than hydrogen will isplace hydrogen from water . Common materials used in this reaction is sodium or potassium . Sodium plus water will produce hydrogen , NaOH, and heat . Other
reactions include the "producer" reaction that was discovered in 1800 . It involves combining heat, carbon, and water. It then yields hydrogen an carbon monoxide .
Bacteria can also be a hydrogen producer. Bacteria and other microorganisms may
release hyd .....

Lighting Advancments
Number of words: 2248 - Number of pages: 9.... conditions were correct. It provided an inexpensive form of lighting, and could be used for cooking and heating. Due to the persistent problem of limited fuel, inhabitants looked for a way to prolong the fuel. (Thwig 29-34)
The next step in lighting that followed was a candle. Candles offered one main advantage over the fire by itself, fuel. A candle was able to provide a long burning light and was relatively inexpensive to produce. Candles were originally made from whale fat. The flame would burn and would slowly use the wick as a fuel and would burn much slower because the wax slowed the bu .....

Virtual Reality - What It Is And How It Works
Number of words: 3281 - Number of pages: 12.... order to create this alternate reality, however, you need to find ways
to create the illusion of reality with a piece of machinery known as the
computer. This is done with several computer-user interfaces used to
simulate the senses. Among these, are stereoscopic glasses to make the
simulated world look real, a 3D auditory display to give depth to sound,
sensor lined gloves to simulate tactile feedback, and head-trackers to
follow the orientation of the head. Since the technology is fairly young,
these interfaces have not been perfected, making for a somewhat cartoonish
simulated realit .....

Killer Whale, The Mighty Dolphin
Number of words: 399 - Number of pages: 2.... they have over and over again been found with harpoons sticking out of their backs. Research soon found that fishermen were shooting them to keep them from eating all of a days catch. This was not the first time something like this was found. In the 1950's The U.S. Navy used machine guns to slaughter hundreds of Killer Whales off of Iceland to protect fishing. After these animals are killed, they are usually thrown away. The meat is very bitter and is not used. Killer Whales also do not produce oil as most other whales do so there is no benefit from that area of trade either.

The Problem With Desertification
Number of words: 1841 - Number of pages: 7.... from a hunting/gathering to pastoralism and agriculture (Kaya and Yokobiri, 1997). Drylands still provide much of our grain and livestock. These areas cover more than 40 percent of the world’s land surface. As these areas decrease in size, so does the reliability of the land to support the human population. In some areas, desertification is occurring to such a degree that some lands can no longer sustain life. Large regions which have been greatly affected include: the Savannas of Africa, the Great Plains and the Pampas of America, the Steppes of Asia, the Outback of Australia, .....

stunt a child's growth is just rumors. is said not to affect children any differently then it does adults.
In another article entitled Coffee may not be so bad… in Science News, November 25, 1995, the author thinks that is an energy booster for athletes. At Oregon Health Sciences University a research team studied six healthy young men. .....
