Hemophilia Manitoba
Number of words: 925 - Number of pages: 4.... can only pass on one of
the two chromosomes. If a male has hemophilia, he will
have normal sons and all of his daughters will be carriers
of the hemophilia disorder because all he can pass on is
the defective X-chromosome.
Males mostly have hemophilia, but women can also have
hemophilia. This is extremely rare though because two
defective X-chromosomes would be needed. In fact, the
first proven case of women having hemophilia was not until
the 1950’s (Bornstein 89). Female carriers are also at
risk. These women are known as asymptomatic .....

Ecstasy The Hug Drug
Number of words: 827 - Number of pages: 4.... a great recipe for intimate contact, which a lot of young people today strive for. The positive feelings that people report are very similar to that of Prozac (anti-depressant drug) and fenfluramine.
MDMA is usually taken orally in the form of pills synthesized by independent labs. They come in different colors, shapes, and sizes. The designer drug may also be taken in the form of a powder and injected into the blood stream for a quicker " high". The actual potency of the pills is determined by the size. They range from 50mg to 300mg depending on where it i .....

Genetics Engineering
Number of words: 655 - Number of pages: 3.... live with genetically engineered items. The FDA
has approved bioengineered tomatoes that ripen without rotting(Dewitt, 1994).
Entire herds of cattle are now being injected with a growth hormone(BST) so that
they will produce more milk than ordinary cattle(Dewitt, 1994). Also drought
resistance grass that needs no moving.
Scientists will soon be able to collect DNA from endangered species.
This DNA could be used to clone more condors, bald eagle, mountain gorillas, and
many other animals. Totally extinct animals may be recreated as well, i.e.
Jurassic Park. I .....

Destruction Of The Ozone Layer
Number of words: 1143 - Number of pages: 5.... sparks from motors also convert oxygen to ozone ( Stoker 1).
The question about the destruction of the ozone layer revolves
around whether human-made CFCs (chloroflurocarbons) used in air-
conditioners and refrigerators are breaking it down. This is the ozone
thinning theory: "CFCs release chlorine into the stratosphere... leading to
ozone destruction and exposing the planet to harmful ultraviolet rays."
Critics who discount the thinning theory still say that chlorine comes from
natural sources like volcanic eruptions and does no permanent damage
(Brooks 422) .....

Cellular Diffusion
Number of words: 595 - Number of pages: 3.... processes of diffusion, osmosis, and active transport, all of which involve only small simple molecules.
Diffusion is the movement of a substance from a region of high concentration, to a region of low concentration of that substance. In other words, a movement down the concentration gradient. Osmosis is very similar to diffusion, however it involves the concentration of water. Osmosis, like diffusion, is a passive process, and does not require energy to occur. Active transport does require energy though, as it involves movement up the concentration gradient. T .....

Is Medical Testing On Animals Ethical
Number of words: 439 - Number of pages: 2.... has no advantage to animals or people.
Animals including dogs, cats, mice, pigs, monkeys, horses, deer, and cattle are commonly used for these senseless experimentations. The other
remaining misfortunate animals come from places a little closer to you and me. Some of them come from animal shelters, some from the “free to a good home” ads in the newspaper, or, even worse, some have been stolen directly from their own yard. Imagine your pet being crammed into a cage with ten other animals waiting to die in these cruel and heartless experiments.

The Search For Black Holes: Both As A Concept And An Understanding
Number of words: 2169 - Number of pages: 8.... allows for a greater understanding of the concept
of spacetime and maybe give us a grasp of both science fiction and science fact.
Hopefully, all the clarification will come by the close of this essay.
A black hole is probably one of the most misunderstood ideas among
people outside of the astronomical and physical communities. Before an
understanding of how it is formed can take place, a bit of an introduction to
stars is necessary. This will shed light (no pun intended) on the black hole
philosophy.
A star is an enormous fire ball, fueled by a nuclear reac .....

The Evils Of Hunting
Number of words: 430 - Number of pages: 2.... to participate in, even for the people who are
hunting for their livelihood. (Satchell 30)
Over the years, hunting has reduced the animal population drastically.
In the 1970's, the number of ducks making annual flights was approximately 91.5
million. In 1995, the number had been reduced to around 64 million. Within 20
years, in short, the duck population was reduced by almost one third, showing
the drastic toll hunting is taking on our wildlife. If we assume that other
species have been reduced in number at approximately the same rate in recent
years, then what .....
