The Serious Problem Of Acid Rain
Number of words: 1892 | Number of pages: 7.... that are near
the Great Lakes, have substances such as limestone or other known antacids
that can neutralize acids entering the body of water thereby protecting it.
However, large areas of Ontario that are near the Pre-Cambrian Shield, with
quartzite or granite based geology and little top soil, do not posses
enough buffering capacity to neutralize even small amounts of acid falling
on the soil and the lakes. Therefore over time, the basic environment
shifts from an alkaline to a acidic one. This is why many lakes in the
Muskoka, Haliburton, Algonquin, Parry Sound and Manitoulin districts could
lose their fisheries if sulfu .....

Down Syndrome 4
Number of words: 1135 | Number of pages: 5.... is called "Down's" in Europe.
In the first part of the twentieth century, there was much speculation of
the cause of Down syndrome. The first people to speculate that it might be
due to chromosomal abnormalities were Waardenberg and Bleyer in the
1930s. But it wasn't until 1959 that Jerome Lejeune and Patricia Jacobs,
working independently, first determined the cause to be trisomy of the 21st
chromosome. Cases of Down syndrome due to translocation and mosaicism
were described over the next three years.
The estimated incidence of Down syndrome is between 1 in 1,000 to 1
in 1,100 live births. Each year approximately .....

The Effects Of Foreign Species Introduction On An Ecosystem
Number of words: 643 | Number of pages: 3.... 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 for decreased fecundity of the flowers.
Another implication of the introductio .....

Interview With An Alien
Number of words: 4277 | Number of pages: 16.... she calls her "live-in
companion," who answers to the name of Hweig.
Mrs. Kannenberg realizes that Hweig would be
explained away by conventional scientists in terms
of split personality or some other form of mental
abberation. Although she does not agree with this
interpretation of her situation, she does not claim to
have any paranormal abilities because of her contact
with Hweig. She does not seek publicity, nor does
she avoid it. She writes down dialogues and insights
she finds to be of particular interest as they occur,
and has given me permission to quote the following
descriptions:

Number of words: 547 | Number of pages: 2.... on Christmas Day 1974.

At this time most people were asleep or partying. By 1:00 AM, the city of Darwin felt the full effect of the cyclone. Some people were outside when it hit but most people got to a safe place for shelter. T .....

Lasers And Their Applications
Number of words: 1998 | Number of pages: 8.... is the process that the laser works on, which was first proposed by Albert Einstein in 1917. When a sufficient number of atoms, either gas solid or liquid, absorb energy so that they are in an excited state of higher energy stimulated emission can occur. Light of a specific wavelength can produce more light with the same phase and direction these light waves will be coherent. Stimulated emission amplifies the coherency of this radiation and gives the radiation a very narrow beam spread.
The combination of light amplification and stimulated emission creates a laser. Laser light is coherent because the atoms are stimulated to e .....

Mitochondrion
Number of words: 215 | Number of pages: 1.... evolved along with them. A
mitochondrian’s main purpose is to burn energy through a slow method of
combustion, which will consume as much air to burn as fire will, just to break
down nutrients into simpler substances. These simpler molecules then bond with
the atoms that will need the energy to function. Then, enzymes in the
mitochondrion break up the atoms and then recapture them again. This time, the
energy atoms will be bonded in a different molecule to form ATP, or adenosine
triphosphate. ATP has an adenosine core and three phosphates attached to it,
hence its name.
These phosphates will store the new energy. ATP can tr .....

How Natural Processes Operate At A Coastal Eographic Environ
Number of words: 1040 | Number of pages: 4.... made of sedimentary rock was eroded back to expose ‘Fisherman’s Rock’ - the shore platform which, made of limestone – tended to erode back slower than the cliff.
The types of wave erosion that caused this are -
Hydraulic Action, when waves hit the cliff, air is forced into cracks, and then as the wave retreats this air expands explosively. Over time the cracks enlarge, weakening the base of the cliff causing erosion.
Attrition is the breakdown of rock particles when they hit Otakamiro point and each other causing the base of the headland to erode.
Chemical Erosion/Corrosion occurs due to the content of .....

Multiple Personality Disorders
