Silverfish
.... months to hatch. The young nymphs are very much like the adults except
for size. Several years are required before they are sexually mature, and they
must mate after each molt if viable eggs are to be produced. Populations do not
build up rapidly because of their slow development rate and the small number of
eggs laid.
ECONOMIC IMPORTANCE: Silverfish sometimes feed on book binding and the paste
that holds on wall paper causing damage to many houses.
IS IT A SOCIAL INSECT? Yes I think that the Silverfish is social because it
lives in colonies.

Spiders
.... 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 mostly active at night. it feeds on
small insects that it paralyzes with its poison.
The Black Widow
The black widow, Latrodectus mactans, is a poisonous spider of the
family Theridiidae, order Araneida. The female, about 1.3 cm (0.5 in) long, is
glossy black, densely clothed with microscopic hairs, and has a red hourglass .....

Black Friday: Tornado In Canada
.... 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 tornado of "Black Friday" touched down on July 31st, 1987 at 2:59 pm.
(See appendix #2 for the torndo path). (See appendix #'s 4&5 for maps locating
the disaster sights). 27 people were killed; 25 people died during the tornado
and 2 died later in the hospital. Hundreds of other people were injured and
thousands were .....

The Application Of Fractal Geometry To Ecology
.... 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 decades. Physicists, chemists,
mathematicians, biologists, computer scientists, and medical researchers are
just a few of the scientists that have found uses for fractals and fractal
geometry.
Ecologists have found fractal geometry to be an extremely useful tool for
describing ecological systems. Many population, community, ecos .....

Cloning
.... 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).
From an individualistic viewpoint, those in favor of cloning human
beings, do not see it as morally, or ethically wrong. Many see it as an
opportunity to have children, or possibly to "re-create" a child who is dying
from a terminal illness. Using a deterministic argument, many infertile couples
are worried that any "governm .....

The Cambrian Period

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 period were
primitive algae.

Creation, Evolution And Intervention: Which Theory Is Correct?
.... 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 resemblance arose through modifications of a
common lineage-for example , that lions tigers and others all descendant from a
cat like ancestor." (Dickey p.42) It had already been a widely accepted theory
that different animals adapt to different modes of life and environmental
conditions. Lamarck argued that physical and mental .....

The Canada Goose
.... 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
(Wormer) The male and female Canada Goose look almost exactly the same except
the female can usually be recognized because it is smaller and less aggressive
(Wormer). Colors also vary but, the color pattern is generally the same for all
the subspecies (Godfrey). The head and neck are dark black with a large white
patch on each cheek which meet under the ch .....

The Dog

ANATOMY
SKELETON
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
made up of approximately 321 bones: 134 form the axial skeleton (skull,
vertebrae, ribs, etc.), and 186 form the appendicular skeleton (appendages). An
extra bone has to be added for male dogs which is the penile bone. The dog is a
digigraded animal (it walks with it’s toes). It lies on it’s third phalanges
which are protected b .....

James Watson's The Double Helix: A Review
.... 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 and Rosy, a drama for the struggle of power between the two.
Watson's "adventure" begins when he receives a grant to leave the United
States and go to Copenhagen to do his postdoctoral work with a biochemist named
Herman Kalckar. Watson found that studying biochemistry was not as exciting as
he hoped it would be; fortunately, .....

Anti-Matter
.... 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
that near the speed of light, is neccesary so that they have a chance of
meeting and combining into anti-hydrogen.1
The problems with research in the field of anti-matter is that when
the anti-matter elements touch matter elements they annihilate each other.
The total combined mass of both elements are released in a spectacular .....

The Downy Woodpecker
.... I have listed
below:
southern downy / Dryobates pubescens Gairdner's woodpecker / Gairdneri pubescens
Batchelder's woodpecker / Leucurus pubescens northern downy / Medianus pubescens
Nelson's downy / Nelsoni pubescens willow woodpecker / Turati pubescens
The downy woodpecker is sometimes reffered to as "little downy."
Behavior Towards Humans
The downy is unquestionably the friendliest woodpecker. A bird lover
in Wisconsin described downies at their feeding station: "The downies will back
down to the suet container on the basswood tree while I sit only a few feet away
on the patio. Even when I walk right u .....
