Acid Rain 4
<view this essay>.... made pollution because of the fact that rain is naturally acidic. This widespread disagreement delayed international action to reduce pollution for some time. However, with the coming of the 1970’s an awareness of acid rain spread, and with that awareness, possible solutions were proposed. These solutions involved making environmental changes on the international, industrial, and personal levels.
Just how does acid rain form, and what consequences does it pose to our environment? There are numerous theories as to the cause of acid rain. However, the most prevalent is the theory that electric generating plants, heating plants, and other industrial plants ha .....

Global Warming

occurs when the levels of greenhouse gasses rise and less infrared light, or heat, escapes the earth's atmosphere. Thus, the temperature experienced on Earth begins to rise. Climate change is a part of the Earth's history. There have been dramatic fluctuations in over all average temperature for the past 150,000 years that suggest a direct association with carbon dioxide levels. In the past the temperature highs and lows have been in tandem with carbon dioxide level highs and lows, this does not seem to be a mere coincidence.
Carbon dioxide cu .....

Cloning 4

A clone, as defined in “The Human Genome Project,” is; 1. a population of genetically identical unicellular organisms or viruses arising from successive replications of a single ancestral unicellular organism or virus. 2. a recombinant clone. 3. the fragment of foreign DNA contained in each member of a recombinant clone. 4. a population of identical cells arising from the culture of a single cell of a certain type, such as a human fibroblast or a rodent-human hybrid cell containing a full set of rodent chromosomes and a single human chromosome. Human embryo cloning starts with a standard in vitro fertilization procedure. Spe .....

Genetic Engineering
<view this essay>.... in a number of cases, nothing less than astonishing. There are five classes of types of , agricultural treatment, somatic gene therapy, germline cell therapy, medical treatment, and eugenic therapy. Many people believe that genetic therapy is morally not right, but there are so many benefits for the world because of it. Some of scientist ideals of how to alter this new science to create the perfect human does in-fact sound crazy. But if was regulated to prevent such things the new science could bring wonders to many peoples lives.
The first form of began with a man named Mendel, a monk in the late nineteenth century. He was the first to even formulate .....

Dinosaurs 2

The Tyrannosaurus was one of the most feared dinosaurs. The word Tyrannosaurus means “tyrant reptile”. Since the
Tyrannosaurus Rex was a meat-eater, its teeth were shaped in zig-zag form which allowed it to cut through meat like a steak knife (Benton 161). It mainly relied on its strength when catching prey. Because it could not swim, many of its prey would run for shelter into water. Also, the .....

Experimental Protein

This correlation helped to draft a regression line, which was useful in finding concentration of protein extract. An electrotransfer on PVDF membrane was done after the gel electrophoresis. These migrations of proteins based on their molecular weight of three solutions. Using the polyacrilamide electrophoresis, proteins were separated based on their molecular weight. Extraction buffer did not produce protein bands. Proteins with huge molecular weight did not travel far from the gel while low molecular weight proteins traveled long di .....

How North Carolina Is Affected By Water Pollution
<view this essay>.... disssolved opxygen.
Only 17% of the surveyed lakes in North CCarolina are impaired for swimming and 6% are impaired for aquatic life uses. A few lakes are impacted by dioxin, metals, and excessive nutrient enrichment. The Champion Paper mill on the Pigeon River is the source of dioxin contamination in Waterville Lake. The State and the mill implemented a dioxin minimization program in the mid-1980s and completed a modernization program in 1993 that will reduce water usage and discharges.
About 94% of the estuaries and sounds in North Carolina fgully support designated uses. Agriculture, urban runoff, septic tanks, and point source discharges are the lea .....

Iron Meteorites
<view this essay>.... are still in the Taisho family today.
The meteorite also had nickel and small amounts of other minerals found within it's body. This gave the three swords an almost wood grain effect to their blades.
Since the iron in the swords was not pure they were quite difficult to make for the master swordsmith Kinimune Okayoshi. Forging it by folding it over and over did not work out very well. So the forging could only be carried out when the metal had gotten so hot it turned white.
Although somewhat irrelevant to the short story about the Shooting Star Swords, meterites do play an important part in science to day, and help scientist decode the birth of ear .....
