Acid Rain
.... regions that are near the Great Lakes, such
substances as limestone or other known antacids 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, there is not 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 sulphur emissio .....

The Application Of Science To Engineering
.... through a circuit thereby
encoding each letter of the alphabet. More efficient transmission facilities
were developed as the mining industry developed. The discovery of electricity
sped up the development of mining through electric lighting and better machinery
and ventilation, which led to better materials for wires and cables. Telegraph
lines were set up along the CPR in 1885 as a convenient root, but also to relay
information about the position of each train along the track to avoid collisions.
The telegraph was also the main source of information for newspapers.
Like the telegraph, the telephone wouldn't have been possi .....

Air Pollution
.... pollutant in smog,
is produced by the interaction of hydrocarbons and nitrogen oxides under the
influence of sunlight. Ozone has also caused serious crop damage. On the other
hand, the discovery in the 1980s that air pollutants such as fluorocarbons are
causing a loss of ozone from the earth's protective ozone layer has caused the
phasing out of these materials.
Current information about the problem
The tall smokestacks used by industries an utilities do not remove
pollutants but simply boost them higher into the atmosphere, thereby reducing
their concentration at the site. These pollutants may then be transported over
large .....

The Roswell Incident
.... in an open field. The issue lay still for almost thirty
years, until the thought of a government cover-up arose.
Society's opinions have changed over the years. Previous to the 1990's,
people have despised the thought of sharing the universe with other intelligent
life forms. Now people are interested in this mysterious phenomenon. People
think it is the blame of the movies and television. By watching this, people are
at a level at which they understand. Not only do these movies entertain, they
inform people about the little information we obtained from the government.
The thought of government cover-ups have been long .....

A Massive Project For The Benefit Of Mankind: A Look At The Human Genome Project
.... ahead of schedule. The project was estimated to have detailed maps
of all of the chromosomes and know the location of most of the human Genes by
1996. Researchers have successfully located the gene and DNA sequence for
Huntington’s Disease on Chromosome 4 and have created a genetic test to
determine if a person carries this gene. "The child of a person with
Huntington's has a 50% chance of inheriting the gene, which inevitably leads to
the disease." Once an individual acquires the gene, it is only a matter of
time before they acquire the disease. Because the medical costs of treating
such persons in terminal illnesse .....

Who Is Responsible For Cleanup Under CERCLA?
.... under CERCLA when it was sold for $25,000, but was appraised at
$200,000, suggesting the decision to sell was for disposal of hazardous
materials.) A vendor is not an owner if it did not own the property at the time
of toxic discharge from the facility.
iii) A parent company may be considered the owner, despite the formation of a
subsidiary with day to day control over operations.
iv) Lenders and secured creditors are liable if they actively participate in
decisions involving either waste treatment, or site development. They are not
liable if they do not participate in management decisions. (silent partners and
banks)

An Argument For Animal Research
.... rats and mice developed
expressly for laboratory use. "Less than 1 percent of experiments involve cats,
dogs, farm animals, nonhuman primates, frogs, fish, and birds." ( ¯Encyclopedia
of Medicine, AMA®, "Animal Experimentation", Page 110.) Animal rights advocates
try to sway public opinion by showing grotesque pictures of destroyed cats, dogs,
farm animals, dolphins, and monkeys which account for less than 1 percent of the
experiments, yet it seems 99 percent of their advertising and campaigning deal
with this one percent. At least the American public realizes even those who
portray ethical righteousness can be wrong. For insta .....

All About Ants (almost)
.... are at least 1
quadrillion living ants on earth(Groliers Œ93).
All species of ants are social. They live in organized communities or colonies,
which may contain anywhere from a few hundred to more than 20 million
individuals. These are organized into a complex system which may contain two or
more castes and sub castes which can be roughly organized into three groups.
Queens, males and workers.
The queen is much larger than the other ants, and has wings until mating. Her
primary task is to lay eggs for the colony. Some colonies have one queen;
others have up to 5000. Queens develop from fertilized ordinary eggs, nobody

Army Ants
.... 100 yards or
more. In the U.S. army we attack countries in different areas to weaken the
force we are attacking. We send out thousands of troops in various directions
and try to surround the source of the location being attacked. For instance, if
there are several locations that needed to be attacked to weaken the enemy, like
their weapon storage or air force base, we send several sets of troops to attack
each individual location. This is very similar to the way army ants set out on a
hunting raid. They will send out thousands of ants at once in two or three
different directions.
When ants go out on their raids, a subgroup call .....

A Study Of Inheritable Traits In Fruit Flies
.... and dihybrid crosses were conducted
with Drosophila melanogaster. Our objective was to examine the inheritance from
one generation to the next. We collected the data from the crosses and analyzed
them in relation to the expected results.
MATERIALS AND METHODS
For the monohybrid cross in this experiment, we used an F1 generation, which
resulted from the mating of a male homozygous wild-type eyed fly with a female
homozygous sepia eyed fly. Males and females are distinguished by differences in
body shape and size. Males have a darker and rounder abdomen in comparison to
females, which are more pointed. Another difference occ .....

Australopithecus
.... fossil was made in 1924. The body of
the australopithecus is smaller than humans, but biffer than chimpanzees. Also,
The brain size of australopithecus is bigger than humans at about 475 cubic
centimeters. This is also biffer than the chipanzees, but the brains were not
developed in most areas. For example speech. The australopithecus species all
had mostly the same features with a low forehead, a "bony ridge"over the eyes, a
flat nose and no chin. Their jaws stuck out and they had large back teeth. Even
today, many more species of australopithecus are being discovered.
Australopithecus anamensis was only named in august 1995, .....
