Hereditary Colon Cancer
... colon cancers. Familial Adenomatous Polyposis Coli (FAP) is very rare and only accounts for one percent of all cases. If a person had FAP, they would develop hundreds or even thousands of colon polyps. These polyps are developed at a very young age, Some people have been known to be as young as 13years of age. Most colon polyps are benign but some become cancerous. Most FAP patients develop cancer by the age of 39. Another form of hereditary cancer is Hereditary Non-Polyposis (HNPCC). HNPCC accounts for five to ten percent of all cases. HNPCC develops also at a young age but not as young as FAP patients. The ...

Ocean Pollution
... chemical pollution. There are approximately 2 trillion travel industries in this world and they all contribute to the chemical pollution, weather it is cruise ships, hotels near the water, or boat tours.
Fishermen also pose a threat to our oceans by over fishing our waters. The way they are going there will not be enough fish for a maximum sustainable yield, and our fish population will die. Fishermen also clean there fish and throw the guts overboard into the ocean.
Industrial, agricultural, household cleaning, gardening, and automotive products are also polluting our ocean. You wouldn't believe it but all of those ...

Effects Of Smoking
... worst side effect of smoking is cancer; it is a life threatening disease that can affect many parts of your body at once. Lung cancer is one of the most common type of cancer caused by smoking. Smoking can cause cancer in the stomach as well in the throat.
Smoking not only attacks your health, but it can also attack your pocketbook. The costs of a single pack of cigarettes has raised substantially in recent years, from 1.75 in the late '80s too nearly over $3.00 now, that’s over $20.00 a carton. Think if you smoked two packs a day for 30 years, multiply that by the price of a pack a cigarettes (think about ...

How Various Mechanisms By Which Substances Cross The Cell Me
... move from higher concentration to a lower
concentration. The side of the membrane that has the higher
concentration is said to have the concentration gradient. It drives
diffusion because substances always move down their concentration
gradient. The pressure gradient also plays a role in diffusion. Where
this is a pressure gradient there is motion of molecules. The pressure
gradient is a difference in pressure between two different points. If
the concentration of one side of the membrane is greater than the
molecules will travel from the higher to lower concentration.
Eventually there will be a dynami ...

The African Penguin

old.
The African Penguin (pheniscus Demersus) is also called the Black-
footed Penguin or the Jackass Penguin. They are called this because of the
loud braying noise, which the little penguins make. This species is the
only species that breeds anywhere in Africa. It breeds on some twenty
islands, from Hollams Bird Island off the coast of Namibia to Bird Island
in Algoa Bay.
At one time the population of the African Penguin was quite large
but some man caused factors has drastically reduced their species. A long
time ago the early European settlers at the Cape of Good Hope realized that
penguin eggs ...

Revolutionary QM212
... around the world.
Chemical Process:
Teams from universities successfully inserted instructions for
building an anti-fluorescein antibody in the DNA of bacteria. This
antibody binds with fluorescein molecules. Into this chunk of material,
they inserted instructions for buildin g a metal-ion binding sight. They
discovered where to put this slot by simulating the antibody on a large
computer. The resulting product revealed an anti-fluorescein antibody which
binds to metal ions. After physically inserting the genetic code in to E.
coli. bacteria, the researchers had a large batch of a new compound which ...

Life and death situations could arise as hospital systems such as, life support and machines used to monitor a patients vital signs are among the systems at risk. Australian hospitals believe that as many as 60% of their machines may not work properly when the date rolls over. Local testing has identified the ultrasound machines and central monitors which have exhibited year 2000 failures. There could be significant threats to personal safety, for example if a ...

Creatine
... With its popularity, you may find at any health or sport product retailer. It sells for roughly $35 a bottle, and is distributed by many manufacturers. serves as an energy reserve in muscle cells. Muscular contraction is powered by the breakdown of ATP (adenosine triphosphate) to ADP (adenosinediphosphate). When all the ATP is broken down, phosphate in the muscle donates a phosphate group to ADP, and further energy reactions can occur. monohydrate is a precursor to phosphate. By supplementing with CM, CP levels in muscle apparently are maximized, and more muscular work can occur, since th ...

The Solar System
... days. The Moons distance from the earth is 384,400 km (238,620miles). Its diameter is 3,476 km (2,160miles). As the moon orbits the earth we see different amounts of it due to the light from the sun. These are the different phases known to man full, new, crescent, half, gibbous, and new moon.
The earth rotates in its axis once a day. The earth is a sphere shaped object. Its diameter is 12,750 km (7,923miles). It takes 23 hours and 56 minutes to rotate once, which is approximately one day. The sun orbits the sun ever 365.25 days. The average surface temperature is 15 degrees. The distance from the sun is 150million ...

Manatees
... uncommon,
and like no other creature on earth. These majestic beasts can float across the
water amazingly fast for its size ("Florida Manatee" 1). They can weigh up to a
ton, and get as long as fifteen feet. They are almost devoid of hair, except for
some whiskers on their face, and they have internal ears on the sides of their
head. Their nostrils are closed by valves, so they can accomplish such feats as
flips and quick turns without losing any air. Manatees have no hind legs, but
instead one big, flat, spatula-like tail (Sentman 327). This feature made people
confuse manatees with mermaids for nearly four ce ...
