The Importance Of The Ozone Layer
Number of pages: 3 | Number of words: 765.... the ozone reacts
with a chloride ion from chlorine monoxide, the ozone molecule is destroyed.
So chlorine monoxide is an ozone destroyer. There is always a certain
amount of chlorine monoxide in the atmosphere.
It is important to remember that ozone is constantly being created and
destroyed in the atmosphere. The amount of ozone in the atmosphere is based
on these reactions. There are many factors that influence the amount of
reactions like season, latitude, and solar cycle. Because of these factors
ozone can vary wildly each day. In the northern latitudes there can be up
to .....

Alcoholism 4
Number of pages: 5 | Number of words: 1374.... nervous system. This depresses mental, motor, and vital functions such as pulse rate, respiration, and blood pressure (Kestler 6). The body can absorb alcohol very quickly, approximately 20% goes directly into the blood stream from the stomach, the rest enters the body through the small intestine. Moments after alcohol enters the blood stream it reaches the Cerebral Cortex, the part of the brain responsible for judgement. The areas of the brain controlling caution and self control are effected first, so most people feel more relaxed. Extremely large doses of alcohol may .....

Phosphates
Number of pages: 4 | Number of words: 865.... to 75% sodium
triphosphate (Na5P3O10), which serves two purposes. Providing an alkaline
solution (pH 9.0 to 10.5) is necessary for effective cleansing and also to tie
up calcium and magnesium ions found in natural waters and prevent them from
interfering with the cleansing role of the detergent.
Eutrophication is the progressive over-fertilization of water, in which
festering masses of algae's blooms, choking rivers and lakes. Phosphorus
compounds act as a fertilizer for all plant life, whether free-floating algae
or more substantial rooted weeds, and are implicated .....

Homo Aquaticus?
Number of pages: 8 | Number of words: 2003.... evolution. With the exception of the olferactory bulb (scent), all
brain structures are larger in humans than in apes. The neocortex (part of the
cerebral cortex), for instance is over three times larger than in chimps, even
though chimps and humans are pretty close to equal in body weight.
Each side of the brain is diveded by the central sulces into independant
halves. Just before the central sulcus lies the post-central cortex, where the
opposite body half (right side for left brain, left side for right brain). Just
in front of the central sulcus lies the pre .....

Effects Of Smoking
Number of pages: 2 | Number of words: 464.... pressure, the flow of blood from their heart, the
heart beat and breathing rate.
Cigarette smoke also contains carbon monoxide, the same
poisonous gases released from a car exhaust pipe. Carbon
monoxide is a colorless and odorless, highly toxic gas that
reduces the amount of oxygen that the blood can carry.
Combined with the effects produced by the nicotine, it
creates an imbalance in the demand for oxygen by the cells
and the amount of oxygen the blood is able to supply.
Tar is another chemical produced from cigarette smoke.
Tar contains at least 30 cancer .....

ADHD On Child Intelligence
Number of pages: 9 | Number of words: 2216.... causes. The present paper seeks to explore current research through investigating the social and bio-genetic influence of . Testing and treatments of those with ADHD will also be discussed. In accordance with Dulcan et al. (1997) ADD, ADD-H, ADHD, although not identical, will be considered interchangeably due to similarity.
Characteristics and Testing of ADHD Intelligence
Even though ADHD occurs in people of every intelligence, a majority of children affected experience academic problems. These children may have specific learning disabilities, such as dyslexia, or ma .....

Endangered Species Study: Jaguars
Number of pages: 2 | Number of words: 431.... have died. The rain forests that the
jaguars inhabit are being torn down to open up lumbering, farming, livestock
raising, and other activities carried out by humans. Killing a jaguar is taking
away a life that is doing no harm to the eco-system. A jaguars' way of living
is much like that of a human, you don't see jaguars killing humans for their
skin.
III. Any endangered specie, including the jaguar, has many different
alternatives in which the government or a national group would have to be
involved. There are several organizations that help the breeding and life of
ma .....

Gulf War Syndrome
Number of pages: 14 | Number of words: 3627.... Nicolson has found that the M. fermentans is nested inside the cells of almost half of all cases. Sinha defines Mycoplasmas as “the smallest self-replicating life form that latch onto white bloodcells, which are part of the body’s disease defenses, with a hooklike tip; then they transmit chemical signal that force blood cells to behave abnormally (Sinha 70).” Mycoplasmas can be difficult to detect, for they burrow deep inside cells. If there was a definition for it would be a disease found after the Gulf War which is related to Mycloplasma fermanta .....
