(Loxosceles reclusa) is a poisonous spider in in the United States. Its mostly
found from Kansas and Missouri, south to Texas, and west to California. Found
in sheltered places indoors and outdoors it is about 10 mm (.4 in.) long and
has an orange-yellow body with a dark violin-shaped design on its back. Its
bite isn't usually fatal to humans, the venom destroys the skin and it may take
a few months to heal. The brown recluse is m .....

Black Friday: Tornado In Canada
.... per second. Eventually the tornado becomes fragmented and dissipates
causing the end of the tornado.
Tornados are the cause of great destruction and devistation in the area
in which they occur. For example the Tri-State Tornado of 1925 occured in the
Kansas, Oklahoma, and Texas States. This tornado was one of the largest
tornados recorded in history. It killed nearly 625 people. However, the
tornado which strikes closest to home has occured on what Canadians have come to
know as "BLACK FRIDAY". .....

The Application Of Fractal Geometry To Ecology
.... to be an
extremely useful tool, not all concur. With all the new insights gained through
the appropriate application of fractal geometry to natural sciences, it is clear
that fractal geometry a useful and valid tool.
New insight into the natural world is just one of the results of the increasing
popularity and use of fractal geometry in the last decade. What are fractals and
what are they good for? Scientists in a variety of disciplines have been trying
to answer this question for the last two dec .....

Cloning
.... in Edinburgh announced on that he had replaced the genetic material of
sheep's egg with the DNA from an adult sheep, and created a lamb (Dolly), the
topic of cloning "created" many new questions of its own. None were as
controversial as: Will they apply this to humans as well? According to Dr.
Wilmut, the answer was "there is no reason in principle why you couldn't do
it"(clone humans), but he added, "All of us would find that offensive."(Wilmut
as quoted by NYTimes, Daniel Callahan, 02/26/97).

The Cambrian Period
.... inland sea called the Saulk sea. Inhabiting this sea, and
the other seas of the primitive world, were Trilobites and Brachiopods .
Trilobites were three - lobed arthropods, unlike other arthropods Trilobites
had primitive ,unspecialized appendages. Brachiopods are simple bi- valve
shellfish that resemble clams. During the Cambrian corals and chrinoids
emerged. Chrinoids are sea animals of the class chrinoidea like the sea lily
and the feather star. The only plant life of the Cambrian peri .....

Creation, Evolution And Intervention: Which Theory Is Correct?
.... that evolution has created
many organisms spread across the globe, some of which have become extinct and
some of which are the plants and animals which live today.
The theory that groups of organisms can be transformed into different organisms
has been suggested many times since the early 1800s, when scientists began
looking for evidence that the evolution process took place. "The most
outstanding evolutionists in the nineteenth century was Jean Baptist de Lamarck,
who argued that the patterns of rese .....

The Canada Goose

(Wormer). This eyesight is essential for flying though, a Canada Goose can see
three quarters of a sphere without moving its head (Wormer). The Canada Goose
also has an acute sense of hearing, it's ears are positioned on the side of it's
head (Wormer). They have either no sense of smell or a very poor one, but this
does not impede the goose in any way (Wormer). Although there is a large
variation in size all subspecies of Canada Geese look the same physically

The skeleton of the dog is the articulated structure, moved by the muscles, that
holds the dog’s body and protects some organs and the nervous system. It also
functions as mineral and blood deposit of the body. The skeleton of a dog is

London at King's College. Wilkins was the initial person that excited Watson on
DNA research. Wilkins had an assistant, Rosalind Franklin (also known as Rosy).
Initially, Wilkins thought that Rosy was supposed to be his assistant in
researching the structure of DNA because of her expertise in crystallography;
however, Rosy did not want to be thought of as anybody's assistant and let her
feelings be known to others. Throughout the book there is a drama between
Wilkins a .....

particles that react so destructively, and their arrangement makes no
difference.
Scientists at CERN in Geneva are working on a device called the
LEAR (low energy anti-proton ring) in an attempt to slow the velocity of
the anti-protons to a billionth of their normal speeds. The slowing of
the anti-protons and positrons, which normally travel at a velocity of

Batchelder's woodpecker / Leucurus pubescens northern downy / Medianus pubescens
Nelson's downy / Nelsoni pubescens willow woodpecker / Turati pubescens

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 .....

Into The Depths Of A Black Hole
.... huge, gigantic, gas clouds
bind together due to attractive forces and form a hot core, combined from
all the energy of the two gas clouds. This energy produced is so great
when it first collides, that a nuclear reaction occurs and the gases within
the star start to burn continuously. The Hydrogen gas is usually the first
type of gas consumed in a star and then other gas elements such as Carbon,
Oxygen, and Helium are consumed.
This chain reaction fuels the star for millions or billions of years

acts as a storage area for calcium which is vital for human metabolism,
houses the bone marrow within its mid cavity and to top it all it is
capable of changing its architecture and mass in response to outside and

interest in microgravity. To fee .....

The Human Brain

PROTECTING THE BRAIN
Twenty-eight bones make up the skull. Eight of these bones are
interlocking plates. These plates form the cranium. The cranium provides
maximum protection with minimum weight, the ideal combination. The other
twenty bones make up the face, jaw and other parts of the skull.
Another way the brain keeps it self safe is by keeping itself in
liquid. Nearly one fifth of the blood pumped by the heart is sent to the
brain. The brain th .....
