Genetic Engeneering
Words: 815 - Pages: 3.... is possible to create a ‘perfect’ organism. Useful characteristics can be transferred from one species to another, this includes animals with plants and vice a versa. As a result it is possible to make foods with high resistance to whether, temperature, pesticides, etc. therefore crop quality and amount grown would increase. Another area of genetic technology involves inserting genes into plants to make them immune to common viruses, this could increase the crop production. If the crop production could be increased, food would become cheaper and easier to obtain. For economical reasons gene technology is better for the producers .....

UFOs
Words: 2685 - Pages: 10.... abductions, will become a reality.
The first reason that is going to be addressed, is the secrecy and
Government coverup of UFOs.
"National Security Agency, or NSA, an acronym often assumed by insiders
to mean 'NEVER SAY ANYTHING' , (Stacey 40) " has been blamed for millions of
UFO governmental cover-ups around the nation. "Our problem is with government
secrecy, because it widens the gap between citizens and the government,
making it much more difficult to participate in the democratic process
(Stacey 40)," says Steven Aftergood while addressing UFO secrecy. The UFO
enigma, or as it is formerly know as the "'Cosmic Watergate' : the ong .....

Coral Reefs And Bleaching Phenomenon
Words: 1422 - Pages: 6.... reefs are among the most diverse and productive of all communities on Earth. They are also the largest biological structures on the planet. The Great Barrier Reef, along the eastern coast of Australia, covers over 2000 kilometers and is said to be visible from the moon (Goreau, 1987). While the size of coral reefs can be enormous, their real impact is on a much smaller scale. Reefs function as food and shelter for fish and marine invertebrates. While the coral itself is an animal, through a symbiotic relationship with the unicellular algae, coral becomes the primary producer in its ocean ecosystem (Richmond 1993). The reefs are fo .....

How Humans And Fish Obtain Oxygen
Words: 779 - Pages: 3.... and trap foregin objects and keep them from entering the lungs. The air completes its path down the trachea when it reaches the bronchus which is a speration of the trachea into the two different lungs it is used to carry oxygen to different parts of the body. These bronchus break into many bronchioles which then branch into many many microscopic tubs that cary the oxygen to every part of the lung till they meet the thin sacs called aveoli. Aveoli are thin sacs in the lungs that carry oxygen in and carbon dioxide out of the blood stream. They diffuse the oxygen into the blood cells that need it and in turn diffuse carbon dixoxide out. Dif .....

Earthquakes 2
Words: 526 - Pages: 2.... breaks along a surface known as a fault plane. Faults are not always visible at the surface of the earth. A fault is a fracture within a rocky mass within the earth's crust. The depth and the length of faults vary tremendously. Earthquakes are caused by faults that are active. An active fault is a fault along which the two sides of the fracture move with respect to each other. An earthquake is caused by the sudden movement of the two sides of the fault.
Faults are divided into three main groups, depending on how they move. There are normal faults which occur in response to pulling or tension. There are thrust faults which are .....

Words: 397 - Pages: 2.... has three times the strength of tempered steel and is being used in bullet proof vests. Another composite will be used to fasten together the sections proposed space stations. have also been used in cars, including the Chevrolet Camaro and the Pontiac Fiero. New are being created with more strength and flexibility by combing two chemically different and producing a block copolymer. Combinations of block co and composites and intended for use in booster rockets and in materials of Earth-orbiting installations. Most common are usually solid, but a new class of is being introduced in a liquid crystal state.
Although these still have .....

Nuclear Power In Ontario
Words: 1130 - Pages: 5.... found it’s new source of electricity, and they were not fully aware consequences that would happen after many years of use. Power projects (later AECL CANDU), based in Toronto. Ontario and Montreal, Quebec became responsible for implementing AECL’s nuclear power program and marketing CANDU reactors. Nuclear power was cheap, if you did not have to worry about the waste. This was the answer to Ontario’s power problems, so they invested in the newest source of power at the time.
Most people believed that nuclear power was a good change in Ontario’s power structure, and there would be no real problems in the future. .....

Adaptation Syndrome
Words: 326 - Pages: 2.... reactions that characterize this early stage is the GAS model. (Author, pg#).
Dr. Selye preformed most of the early work on the adaptation syndrome. His experiments in general looked at harmful stimuli on the response of the body. In an experiment, Seyle exposed a large number of rats to a refrigerated room where the temperature was near freezing,(Author pg#) ββ¦during the first 48 hours they developed the typical manifestations of the alarm reaction. This was proved by killing ten animals at the end of the second day; all of them had large fat-free adrenals, small thymuses, and stomach ulcers.β (Seyle, 1956; 88). This experi .....

Information About Transgenic Organisms
Words: 329 - Pages: 2.... used to treat human diseases. For example, bacteria can produce the hormone insulin, which is used to treat diabetes. Such uses of transgenic organisms are widely referred to as genetic engineering.
Transgenic organisms have proved very useful in analyzing the function of gene products because a specific gene can be expressed in all the cells of a transgenic organism and the effect on the organism's development and function can then be monitored. It is also possible to use transgenic procedures to produce animals in which a specific gene has been deactivated in all its body cells. Certain genetic disorders of humans can be studied with th .....

Alternative Fuel Source
Words: 349 - Pages: 2.... is the key to providing large enough amounts of raw biomass at costs low enough to enable cellulose (the hydrocarbon provider necessary for fuel production) to recapture lost markets. This versatility has led people to believe it is the only biomass resource capable of making America energy independent.
There is only one catch: the federal government prohibited the growth of hemp in 1938. There were also theories that the major energy industries of the late 30s collaborated to ensure a petroleum-based energy market. Regardless of laws, let us consider hypotheticals. Farmers would be practically guaranteed profit if they could grow hemp f .....
