The Roswell Incident
.... our minds to the capacity of
excepting all, has remained one of the most controversial issues today. In
Roswell, New Mexico, 1947, a strange occurrence arises. An alien craft from
outer space crashed 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 interest .....

A Massive Project For The Benefit Of Mankind: A Look At The Human Genome Project
.... for the project. There also have been
technological advances and discoveries that have helped to speed up the project.
This automation may help to reduce the cost and help the project to meet its
objectives 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 .....

Who Is Responsible For Cleanup Under CERCLA?
.... corporations are permissible
ii) If one is the owner or operator, liability may attach even if some other
party in the past placed hazardous wastes there. ( The seller of a foundry was
found liable 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, d .....

An Argument For Animal Research
.... treatment of animals during experimentation, but the use of animals in
research for the benefit of all people is and always will be justifiable.
Over 99 percent of all animal experiments are on 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 grotes .....

Solar Oven
.... it will work:
It will work because the cold air under the box will be separated by
four (4) wood pegs. The black, non-glossy paint will attract heat, rather than
reflect it. The glass, double panel, will allow heat to pass through, but not
allow it to escape. The charcoal cubes and shavings will absorb the heat in the
box and store the excess heat allowing the flow to continuously warm the oven.
The tin foil will reflect heat and subsequently heat up the oven. The
polyurethane material will trap t .....

All About Ants (almost)
.... Insects Œ68). These remarkably adaptive creatures are found in
some form on all continents and all habitats but the extreme arctics. Their
success is manifested in the claim that at any time there 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 .....

Army Ants
.... made by ants are carried out by "armies" of thousands
of ants and set out from the bivouac in various directions. They form two or
three parties going out simultaneously in different directions for 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 wea .....

A Study Of Inheritable Traits In Fruit Flies
.... it develops into an adult through metamorphosis. Upon
reaching adulthood, the flies are ready to mate and produce the next generation
of Drosophila melanogaster.
During this experiment, monohybrid 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, .....

Australopithecus

million and 1.1 million years old. There has also been evidence that the
australopithecus "man" lived in australia where fossils have also been found.
The first discovery of an 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 .....

The Effects Of Antibiotics On Bacterial Growth
.... live are known as anaerobes.
The shape of specific bacteria provides for the next step in the
identification process. Spherical bacteria are called cocci; the bacteria that
have a rodlike shape are known as bacilli; corkscrew shaped bacteria are
spirilla; and filamentous is the term for bacteria with a threadlike appearance.
Hans Christian Joachim Gram, a Danish microbiologist, developed a method
for distinguishing bacteria by their different reaction to a stain. The
process of applying Gram’s stai .....

A. Preparation :
1. Bacteria is cultivated on agar jelly in an incubator at 25°C for 24 hours. 2.
Obtain a microscope slide and with a toothpick, smear a thin coat of the
bacteria sample onto the slide 3. Cover the smear with a drop Crystal Violet
and leave standing for 20 seconds 4. Wash off the stain with distilled water;

Bats
.... has the most distinguishing feature of a bat, wings (Lauber 9). The upper
arm of the bat is short while the forearm is very long. The wrist is very
small and from it comes the thumb and the four longer fingers. The thumb is
short and used for climbing or walking. The fingers are long and thin.
Interlocking the fingers is the wing. This set up of having the fingers in the
wing gives the bat amazing flight maneuverability (Honders 22). These bones
look similar to a human hand. They are connected by r .....

Becoming An Ecologist Is An Exciting Venture
.... of nature, wherever it
occurs, is what you will investigate and analyze"(17).
Since a career as an ecologist is usually long term, there are certain
characteristics a person should have in order to maintain a successful career.
One of these characteristics that is the most important is patience. Patience
is important because as an ecologist a person will have to at some point in
their career talk to another person who knows nothing of or about ecology.
Another reason why patience is important is b .....

The Big Bang

The Steady State model says that the universe does not evolve or change in
time. There was no beginning in the past, nor will there be change in the
future. This model assumes the perfect cosmological principle. This principle
says that the universe is the same everywhere on the large scale, at all times.2
It maintains the same average density of matter forever.
There are observational evidences found that can prove the Big Bang model
is more reasonable than the Steady State m .....

Star Mars

technology slightly provides strong, useful information about the red planet
because of the vast distance between us.
While people such as Steven Spielberg and George Lucas try to convince
us with hundred million dollar movies that we are not alone, engineers and
geologists like from the NASA-Stanford University team pursue, based on true
evidence, the idea of possible life on Mars. However, the burden of proof is
sometimes too heavy even based o .....
