Black Friday: Tornado In Canada
<view this essay>.... combination of
severe thunderstorms and sweltering heat are the breeding grounds for a
tornados' formation. The first sign of a tornado is a strong dust whirlwind
along with a funnel growing from the storm cloud. A more organized funnel
descends farther from the cloud, sometimes even touching the ground. Funnel
winds generally move counterclockwise and the funnel can move slowly or at about
100/ft 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, Okla .....

Genetic Engineering And Its Fu
<view this essay>.... have. First, and most important some believe it is unethical to modify life. Changing life to service us is not morally wrong. It is not inhuman either. Of course, if you believe using animals for scientific research is morally wrong that's your belief, I am stating that genetically enhancing them to be better research specimens is not unethical. My reason behind this is that we don't just do research in order to infect and kill off the mice, we do it so one day we will have a cure for cancer and can save hundreds of thousands of human lives. Of course if you value the life of a mouse over a human then you would see differently. Some fear that this science is t .....

Alternative Medicine
<view this essay>.... Organizations (“HMO”). The primary emphasis and, for
that matter, the only reason for the existence of insurance
companies is a single word, profit. More specifically, premiums
less costs provide the all important profit margin, the life
blood of the insurance industry. By not providing coverage for
the billion dollar industry of alternative treatments, insurance
companies are keeping the cost of the premiums down but at the
same time not allowing their customers to use complementary
treatments such as chiropractic to prevent or cure illness. The
more rigid and restrictive the policy provisos, the more
assurance for the companies that they w .....

The Effects Of Antibiotics On Bacterial Growth
<view this essay>.... contain lipids but lack certain chemicals in
their cell wall. Eubacteria are all other bacteria. Most of them are
phototrophic, i.e. they use the sun’s energy as food through the process of
photosynthesis.
Another classification of bacteria is according to their need of oxygen
to live. Those who do require oxygen to live are considered aerobes. The
bacteria who don’t use oxygen to 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 Atomic Theory
<view this essay>.... inert gases, and their failure to react with other substances.
In 1969 a Russian chemist, named Mendeleyev who a renowned teacher developed, the periodic law
of the properties of the chemical elements (which states that elements show a regular pattern when they are
arranged according to their atomic masses). Mendeleyev wrote a two-volume book called Principles of chemistry
(1868-1870), which later became a classic. These books included an improved version of the periodic table.
Sir Joseph Thomson, another important person in the development of the atomic theory, was born in
1906. Thomson won the Nobel Prize in physics (1906) for his work in the con .....

The Prairie Dog: Friend Or Foe?
<view this essay>.... governments, wipeouts from flea-borne plague, recreational shooting, and habitat destruction have left prairie dogs inhabiting only two percent of their range from Mexico to Canada. Biologists say that the resulting smaller, more fragmented prairie dog towns leave the animals vulnerable to disease and natural catastrophes. Populations are even limited on the land that is available. Current policies on National Grasslands and other federal lands typically limit prairie dogs to small percentages of available potential habitat.
Prairie dogs are essential to our prairie ecosystem. Many species dependent on prairie dogs for prey and habitat are diminishing in d .....

Deciduous Forests
<view this essay>.... temperate woodlands, and temperate evergreen forest) our lab data deals
with characteristics of the temperate deciduous forest. This forest type once
covered large portions of Eurasia, South America, and North America. As with
most native forests, they have been cleared so that the land could be used for
farming or residential use. The temperate deciduous forests of North America
were more diverse than the same type of forests in Europe due to glacial history.
Glacial action dumped till as the ice edge retreated, and North America
inherited a fertile soil base. Soil type is an important factor for which
species of trees can thrive in an area. The gen .....

Earthquakes

Aristotle believed that "mild were caused by wind escaping from caves within the bowels of the earth and severe shocks were by gales that found their way into great subterranean caverns" (Matthys 87). However, with modern technology we found that what actually causes is tectonic plates which on average move only two inches per year they are driven by convection currents which is the upward movement of heated particles rising from the earth's molten core. As the plates are driven against each other one will try to and event .....
