In complete , there is lack of pigmentation in skin and hair, as well as in retinal and iris tissue; in incomplete , skin and hair may vary from pale to normal; in ocular , function may vary from norma to impaired. Impairments may involve the retina and iris. If a person has then they usually have somewhere between 20/70 and 20/200 visual. Ty-Neg or also called type 1A results from a genetic defect in an enzyme called tyrosinase. Tyrosinase helps the body to change the amino acid tyrosine into pigment. An amino acid is a building block of protien. is passed from parent to their kid through genes. For nearly a .....

Aquired Dyslexia
Number of words: 1877 | Number of pages: 7.... processing routes, the Non Lexical Route and the Lexical route.
A model produced based on theories from Coltheart (1981) shows that there are several routes to speech production in the brain. The eye first identifies the printed word. In the adult skilled reader the eye does not move in a smooth pattern but actually jumps to certain focus points in a sentence the brain itself actually fills in the missing words. It does this by top down processing in which the brain applies words to the sentence to make the overall meaning correct. The eye does not move smoothly but actually jumps from point to point. The term given to the peri .....

Human Cloning -
Number of words: 1292 | Number of pages: 5.... (religoustolerance). Although the ban was lifted during the first days of Bill Clinton’s presidency, in 1997 he sent a bill to congress marked “immediate consideration and prompt enactment” stating that it would be illegal to create a human clone whether in private or public laboratories. Along with the US ban, nineteen European countries including Denmark, Estonia, Finland, France, Greece, Iceland, Italy, Latvia, Luxembourg, Moldova, Sweden, Macedonia, and Turkey, signed a protocol that would commit their countries to ban by law any intervention seeking to create human beings genetically identical to .....

Electrolytes
Number of words: 612 | Number of pages: 3.... particles are
ionically (electrically) bonded together. They already made out of cations
and anions, but in their solid state the ions are locked into position in
their crystal structure, and can’t move around. When the ionic compound is
dissolved into water the water molecules, which are polar,(having a
positive and a negative end) will be attracted to the positive ions. This
attraction of different charges will create tension in the crystal and it
will overcome the attice (the arrangement of molecules in a crystalline
solid) energy keeping the crystal in place. Once this happens the cations
will be surrounded by water mol .....

Compatisome Of Upper And Lower Rock Shores Pools
Number of words: 3210 | Number of pages: 12.... different to those of a ‘normal’ marine environment. The rock pools spend some of their time completely submerged by the sea and other times exposed to the air. When exposed the organisms of the rock pool are part of a much smaller body of water than normal. This smaller volume of exposed water is likely to be changed significantly, mostly as a result of heating by the sun (Brehaut, 1982).
Heating of exposed rock pools mean that the organisms within have to cope with considerable abiotic variations There are three major factors which fluctuate in rock pools: 1. Temperature- this changes as a small body of water changes temper .....

Sickle Cell Anemia
Number of words: 2576 | Number of pages: 10.... Pauling discovered that an abnormal form of hemoglobin was the reason for the sickness in sickle cell patients. These two took a train together and started talking about . Castle told Pauling about how the cells in sickle cell patients sickled when their oxygen level is low. Paling was amazed by this conversation and did further research on the disease. After that
Pauling was able to tell which patient had sickle cell trait and which one had the disease.
In 1956, Dr. Vernon Ingram made a distinction between normal and abnormal hemoglobin. Dr. Ingram used Pauling’s test to find the key difference. Like other proteins, hemog .....

Uranium: Nuclear Friend Or Nuclear Foe
Number of words: 2697 | Number of pages: 10.... deaths were due
to lung cancer. But with their scientific knowledge the doctors could only
assume that the deaths were caused by the inhalation of arsenic. Later
studies between 1900 and 1940 found that the deaths were caused by
radiation in the mines.
The radiation the miners were exposed to would later be identified
as uranium. Uranium is a natural occurring element, it has a atomic count
of 92. Uranium is easily identified by its properties. Uranium melts at
about 1132°C, boils at about 3818°C, and has a specific gravity of 19.05 at
25°C. Uranium has three crystalline forms, of which the one that forms at
about 770°C is .....

Asteroid Defense
Number of words: 346 | Number of pages: 2.... a very scary thought. In the past
we have been very lucky with where asteroids have hit our earth. Back in 1908
in the Tunguska region of Siberia, an object from space hit there causing miles
of forest to be devastated. If that same object had hit New York, it would have
probably been like a 20 megaton bomb going off in Times Square. That would have
completely altered history. What makes it worse is that it is thought that a
small comet hit in Tunguska. What if a huge comet had hit there? These
examples are very good reasons why I think that humankind needs to come up with
a way to stop asteroids or any other type of objec .....

Environmental Pollution
Number of words: 1277 | Number of pages: 5.... fossil fuels, and CFCs from aerosols. Every bit of this
harms our atmosphere. Factories and transportation depend on huge amounts of
fuel billions of tons of coal and oil are consumed around the world every year.
When these fuels burn they introduce smoke and other, less visible, by-products
into the atmosphere. Although wind and rain occasionally wash away the smoke
given off by power plants and automobiles, the cumulative effect of air
pollution poses a grave threat to humans and the environment. A big example of
smog is LA you can see the smog just hovering above the city. I don't think any
human alive should be subject to th .....
