The Peregrine Falcon
Number of Words: 1782 / Number of Pages: 7
... called this falcon a duck hawk. That was a poor name,
since falcons aren't hawks and they rarely kill ducks. The American
peregrine was once found all across the eastern United States and southern
Canada. In the west, the species was found from Mexico to California. DDT
poisoning hit this subspecies the hardest. Even today, naturalists are
still working hard to save the American peregrine from extinction.
The smaller tundra peregrine (Falco peregrinus tundrius) lives
farther north. Tundra peregrines range across the treeless regions of
Alaska and Canada. They are also found in Greenland. ...

Quantum Computing
Number of Words: 2038 / Number of Pages: 8
... description of the world in which an object can apparently be in more than one place at the same time, in which a particle can penetrate a barrier without breaking it, in which something can be both a wave and a particle, and in which widely separated particles can cooperate in an almost psychic fashion, is bound to be both thrilling and bemusing. Niels Bohr, one of the founders of the theory, once remarked that anybody who is not shocked by quantum mechanics hasn't understood it.
For decades the complexity and incredibility of the quantum world was an obstacle to the theory being known outside the sc ...

From Water To Land
Number of Words: 1190 / Number of Pages: 5
... ancestry, but still anatomically far from its terrestrial relatives. These creatures still lived in water, but they had a lot of the terrestrial tetrapod anatomical characteristics.
Introduction:
Before tetrapods existed, all vertebrates were confined to living in aquatic habitats. The only animals that lived on land were arthropods. Through natural adaptations, the fish developed into amphibians. This colossal stage of change made necessary the evolution of new ways of breathing, locomotion, and reproduction. Paleontologists needed to understand how this transition took place. If the changes in anato ...

Female Circumcision
Number of Words: 3203 / Number of Pages: 12
... child abuse and a violation of human rights, it remains a revered rite of passage in parts of Africa, the Middle East and Southeast Asia. According to the World Health Organization, circumcision dates back almost 4,000 years. No one knows exactly how the practice began, though scholars speculate its origins lay somewhere along the Nile Valley.
The reasons for performing this procedure are almost as numerous as it's consequences. The procedure can simply be a small but painful nick across the hood of the clitoris, but is typically more severe. The most severe type of circumcision is called infibulati ...

Predators And Ecosystem Management
Number of Words: 419 / Number of Pages: 2
... it's been
possible for us to observe the kelp-forest ecosystem over-time, thanks to the
massive growth of the sea otters population we observed the change from otter-
free to otter-dominated.
This article relates to many aspects of our textbook. On page 89 in
chapter 5 the text explains what an ecosystem is, defined by the book, it's a
community of species interacting with one another where there is a non-living
environment. In this case the otter and kelp-forests ecosystems a coastal
ecosystem. As mentioned in the book, the food chain is involved in the sequence
of events with the organism that a ...

Nuclear Power: Cons
Number of Words: 2010 / Number of Pages: 8
... the dangers involved with fission could be
solved by adopting these newer, safer methods. A main source of energy that
could lead the way for the near future is solar energy. It is clean efficient
and is already a large part of American and Canadian electricity production.
"Solar energy already supplies about 6% of the nation's [U.S.A] energy ... the
industry is still in an embryonic stage, and opportunity exists for increasing
this contribution by ten times from current levels." (Maidique, 92) It is
obvious that solar power will become a large part of the electricity production
around the world. With ...

The Big Bang Theory Vs Biblical Views
Number of Words: 351 / Number of Pages: 2
... the confines of an atomic nucleus. Known as a singularity, this is the
moment before creation when space and time did not exist. According to the
prevailing cosmological models that explain our universe, an ineffable
explosion, trillions of degrees in temperature on any measurement scale,
that was infinitely dense, created not only fundamental subatomic particles
and thus matter and energy but space and time itself. Cosmology theorists
combined with the observations of their astronomy colleagues have been able
to reconstruct the primordial chronology of events known as the big bang.

Heroin A Long Dark Path
Number of Words: 1871 / Number of Pages: 7
... heroin can also be cut with strychnine or other poisons. The reason heroin is one of the most deadly drugs is because there are varying rates at which the drug is diluted. Therefore a user never knows exactly how pure the drug is, hence, they do not know how much of the drug they should take, often leading to an overdose. Like alcohol, heroin is a depressant that slows down all the body functions. But heroin differs from alcohol in two very significant ways. It does not destroy body organs, like the liver or kidney, the way alcohol does. That is why heroin dependency can last for years. Second, an ...

... in the upper lid to squeeze the lachrymal gland. This produces tears that flow too fast to be drained away. The lashes catch many flying particles that otherwise would enter the . As further protection, the lids automatically close when an object suddenly moves close to the .
The eye is made of 3 coats, or tunics. The outermost coat consists of the cornea and the sclera. The middle coat contains the main blood supply to the eye and consists of the choroid, the ciliary body, and the Iris. The innermost layer is the retina.
The Sclera, or the white of the eye, is composed of tough fibrous t ...

The Effects Of Foreign Species Introduction On An Ecosystem
Number of Words: 643 / Number of Pages: 3
... in the ecosystem is reduced, the ability of the
ecosystem to grow, or the biotic potential, is as well reduced. More species
residing in an ecosystem which depend on each other allows for a greater chance
of survival and perpetuation. This may occur for several reasons, for example a
bee and a flower. The bee requires the pollen of the flower to make its honey.
However, while gathering the pollen from the flowers, it transfers some of the
pollen to female flowers, allowing them to make seeds and spawn further
generations. However, a foreign species may, for example, eat the bees
therefore allowing ...
