Gulf War Syndrome
Words: 3627 - Pages: 14.... the syndrome as Mycoplasma fermentans. Sinha also stated that Mycoplasma fermentan was “the most poorly studied bug on the list (Sinha 70).” 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 .....

Genetic Engineering 5
Words: 1126 - Pages: 5.... one’s moral standards (Epstein 5). Others argue that such inventions as human clones, which are genetically constructed humans, and other genetically created figures, are wrong and should be stopped (Epstein 5). Overwhelming textual evidence proves that genetic engineering is not beneficial to society. Accordingly, genetic engineering is unethical and therefore should be stopped.
One reason why genetic engineering should cease is because genetic engineering disrupts society’s moral values and causes society to act out in destructive ways. An online survey done by Time Magazine in 1997, found that 11% of those who were intervi .....

Adrenal Gland
Words: 1019 - Pages: 4.... cells of the pancreas. Epinephrine is called the “fight” or “flight” hormone.
The actions of epinephrine and norepinephrine are generally similar, although they differ from each other in their effects.
Norepinephrine constricts almost all blood vessels. Norepinephrine is formed by intravenous infusion to combat the fall in blood pressure associated with types of shock. Norepinephrine is formed in the body from the amino acid tyrosine, and epinephrine is formed from norepinephrine.
Mineralocorticoids steroids control the overall body fluid. Mineralocorticoids are critical to regulate concentrations of minerals in extracellu .....

The Element Carbon And Its Importance
Words: 1089 - Pages: 4.... of amorphous carbon, called carbon black, is formed. Carbon black is
used in rubber products and paint. Charcoal is used as a cooking fuel and
ivory black, made by heating ivory, is used as a pigment in paint.
Most carbon occurs in combination with other elements. For example,
the carbon dioxide in the air is a compound of carbon and oxygen. Other
compounds containing carbon include minerals such as limestone, and fuels
such as coal and petroleum. Carbon compounds make up the living tissues of
all animals and plants. There are over one million known carbon compounds
(still growing rapidly every year), which is over the sum tot .....

Genetic Engineering And DNA Technology In Agricultural Productivity
Words: 758 - Pages: 3.... have been mapped for important traits than waiting until they are fully-grown. This way, animals and plants are recognized at an earlier state whether or not they will be useful in breeding. DNA fingerprinting also makes it easier to ensure that organisms are homozygous for certain, desirable traits, rather than relying on just the phenotypes which may actually prove to be heterozygous and can, therefore, pass on the traits which were intended to be removed.
Even the knowledge of a single gene can have a major impact. Just by locating a single pathogen-resistant trait or adding or deleting a single gene can vastly improve the overall qua .....

The Destruction Of Red Tides
Words: 885 - Pages: 4.... and falls of the sea." (New York Times: Aug. 27,1997) Some cases of red tides do not show any change in the color of the water at all. This makes a red tide very hard to predict or find.
Red tides often occur when fresh water runoff creates a stratified surface layer above colder nutrient-rich waters. "heavy rains might have helped the red tides develop by pouring fresh water and nutrients into surrounding sea waters," (New York Times: Sept. 19, 1996) Fast growing algae quickly strip away nutrients in the upper layer, leaving nitrogen and phosphorus only below the interface of the layers, called the pycnocline. Many swim at speeds of 10 .....

The Ozone Layer
Words: 1504 - Pages: 6.... from mixing cooler air outside
with the warmer air inside.
Although water is the most important factor in the greenhouse effect, is
a major reason why human regions experience less cooling at night than do dry
regions. Changes in both water and carbon dioxide play an important role in
climate changes. For this reason many scientist have expressed concerns over
the global increase of carbon dioxide in resent decades, largely as a result of
the burring of fossil fuels. In many other factors of the earth’s present
climate remain more or less constant, the carbon dioxide increase should raise
the average temperature at the earth’s su .....

Penguins: The Eyes Have It!
Words: 1047 - Pages: 4.... a different story-or has been up to now. Waddling along
on their flat little feet, eyes fixed intently on the ground, penguins
appear myopic, inefficient and generally out of place.
In fact the reverse is true. During a recent stay on the Falkland Islands,
a Canadian researcher discovered that penguins are able to recognize
individuals and navigate the rocky terrain on which they live quite well.
Long of body and short of leg, they probably poke their heads forward as
an aid to balance. And as for looking at the ground, they're merely-like
us-keeping an eye on where they're going.
The human eye is adapted for aerial vision, which is why .....

The second day in town, the grandfather did something that no one could believe. He just awoke form his nap when he heard a noise that was very familiar to him. It was the sound of a train whistle. He ran running to the window and saw the smoke from a train headed toward town. A memory was triggered in his head and he went running from the house toward the train. While running to the train, he star .....

Plastic Not Paper

This means it takes seven trucks to deliver the same amount of paper as one
plastic delivering truck. Talk about a big waste of gas. Plastic bags cost
about ¼ of a cent to make, while paper cost close to 3 cents. This is money we
save as well as the store owner. This is a lot of money that is going to
waste considering that plastic bags are so much more practical then paper. You
can use them for lots of other things. You can take on trips to the grocery
store, your can protect dry clothing from wet towels in an exercise bag. You
can line your house hold waste basket with them, you tote dry sh .....
