Lime Disease
Words: 916 - Pages: 4.... or plants. Borrelia grow slowly
compared to most bacteria. They elongate for 12 to 24 hours before dividing into two
cells. B. burgdorferi is approximately 20 to um long and 0.2 to 0.25 um wide, with 7 to
11 flagella. More than 30 proteins are contained within B. burgdorferi1. This bacteria
uses white-footed mice, mosquitoes, and deer as their hosts.
This disease does not discriminate between sex and age; male and female, as
well as old and young are affected. It is widely distributed around the world in the
temperate zones3. A person is infected when a black-legged tick imbeds itself into
them while out in the open in w .....

Death Of A Planet
Words: 1460 - Pages: 6.... smog. Ground level ozone is responsible for irritating eyes,
damaging lungs, and it complicating respiratory problems. Hydrocarbons aren't
the only pollutants released through car exhaust.
Two more pollutants released through car exhaust are carbon monoxide and
nitrogen oxide. The first reduces the flow of oxygen to the bloodstream, and
could harm people with heart disease. Nitrogen oxide is formed when a car
engine gets hot. It contains chemicals that aid in the formation of ground
level ozone as well as acid rain (2 factsheet, OMS-5). Acid rain destroys the
outsides of buildings, statues, etc. Acid rain can also contaminate drink .....

are dangerous to our environment, but in most cases they help more than they hurt. For example, it is estimated that the food supply would reduce by forty to fifty percent without the use of on our crops. The FDA, EPA, and the Department of Agriculture try to ensure that the use of is necessary to the extent in which they actually are used by performing studies and proposing bills and laws to Congress. There is no dispute that are harmful. The purpose of is to kill certain fungi, pl .....

Lung Cancer 2
Words: 1407 - Pages: 6.... are common in smokers. They develop in the central or peripheral part of the lungs and the lymph glands.
Small cell carcinoma tumors are small and fragile. They are divided into groups by their shapes. The term “oat cell carcinoma” is used to develop in smokers and usually in the central part of the lung. They spread by the lymph glands and into the blood stream early. This type of tumors can only be seen through an electron microscope on high magnification. A rare type of lung cancer, which develops from hormone producing cells are carcinoid tumors. They have a much less malignant course than small cell carcinoma.

Mans Discovery Of Fossil Fuels Could Be His Downfall. Discus
Words: 1624 - Pages: 6.... the major industries. The major fuel for steam engines was firewood. By the end of the 1800’s, the demand for energy was ever increasing and firewood around industrial centres was becoming scarce. This led to a switch to coal as the major source for fuel and energy. As well as powering steam engines coal became widely used for heating, cooking and industrial processes.
Air pollution during the Industrial revolution was far worse than anything seen today. Apart from the smoke and fumes obscuring visibility, they also caused major health problems to the inhabitants of the industrial areas reducing life expectancies, predominantly with re .....

Carbon Dioxide Poisoning
Words: 1104 - Pages: 5.... or CO as it is also called, is an odorless, colorless, and deadly gas given off when any fuel is incompletely burned by, for example, a furnace or water heater (Marable 97). Unlike a fire where you can immediately see smoke and flames, carbon monoxide poisoning gives no physical evidence of its presence. But, when taught to see and look for the warning signs of carbon monoxide, deaths in the home due to carbon monoxide poisoning can be prevented.
Sometimes, in a home the hot water supply is low, or the furnace fails to keep the house warm. A natural reaction in any of these situations would be to turn up the tempeture on both appliances .....

Comets

Pressure builds up underneath the crust and causes the surface to bubble up in some places. Eventually, the weak spots of the crust break open from the pressure, and the gas shoots outward; this is referred to by astronomers as a jet. Dust that had been mixed in with the gas is also pushed out, and as more jets appear, a small gas and dust shell forms around the nucleus, and this is called the coma.
The coma, also called the head, is a dense cloud of water, carbon dioxide and other gases and c .....

Genetic Engineering And Its Fu
Words: 1735 - Pages: 7.... 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 too powerful, granted we shouldn't let just anyone be able to modify bacteria, or the human genome, but we shouldn't let our fears blind us to the possible benefits of wide-scale genetic engineering.
Medical uses for this technolog .....

The History of the Forest
Forests have long been recognized as having vast power, both through their
potential and how it has been viewed by humans, as well as through their effect
on humans in sometimes subtle ways. The inherent properties of wood have always
made it attractive as a versatile resource but there are other, more subtle ways
in which it affects people. The tropical rainforests, responsible for producing
most of the earth's breathable air, have been given the lofty title of "lungs of
the Earth," and as stated by the Canadian En .....
