... of the polar ice caps and hence a major rise in sea level, along with other severe environmental agitation. An example of a runaway greenhouse effect is Earth's near-twin planetary neighbor Venus. Because of Venus's thick CO2 atmosphere, the planet's cloud-covered surface is hot enough to melt lead. Water vapor is an important "greenhouse" gas. It is a major reason why humid regions experience less cooling at night than do dry regions. However, variations in the atmosphere's CO2 content are what have played a major role in past climatic changes. In recent decades there has been a global increase in atmospheric CO2, largely as a result of the burning o ...

... without solvents. There are two ways to be able to have ions that are able to conduct electricity, the dissociation of Ionic Compounds, and the Ionization of Polar Covalent Molecular Substances. The Dissociation of Ionic Compounds is where particles are ionically (electrically) bonded together. They already made out of cations and anions, but in their solid state the ions are locked into position in their crystal structure, and can’t move around. When the ionic compound is dissolved into water the water molecules, which are polar,(having a positive and a negative end) will be attracted to the positive ions. This attraction of different charges will create ...

... mass. So concentrated, that no object can escape its gravitational pull. In other words, once you get caught by it’s graviational pull, you aren’t getting out again. The velocity you need to break away from a graviational pull is called the "escape velocity". Roughly, earth’s escape velocity is about 25,000 M.P.H. (11.2 kilometers/second). Earth’s mass is nothing compared to the mass of a star that has the potential to become a black hole. A black hole has so much mass in such a small area, that its escape velocity is greater than the speed of light. So if were all living on earth, and earth was a black hole, we would need to go at the speed of light in ...

... about 2 days of these symptoms you start to "crash". A crash is when you vomit uncontrollably until there is nothing left to vomit (you vomit blood, bile and other liquids of the body), you suffer from diarrhea, limited kidney function, internal and external bleeding, you bleed from every opening on your body, blood fails to clot, so if you get cut in any way your body will never stop bleeding from that wound. Ebola could spread and infect everyone in the world in 48 hours. Marburg, Germany In this small German town people were taking tests on African monkeys. These monkeys were infected with the infamous Ebola virus. What's horrifying about Ebola is that the viru ...

... 4 to 5 years old. Bald eagles are believed to live 30 years or longer in the wild, and even longer in captivity. They mate for life and build huge nests in the tops of large trees near rivers, lakes, marshes, or other wetland areas. Nests are often reused year after year. With additions to the nests made annually, some may reach 10 feet across and weigh as much as 2,000 pounds. Although bald eagles may range over great distances, they usually return to nest within 100 miles of where they were raised. Bald eagles normally lay two to three eggs once a year and the eggs hatch after about 35 days. The young eagles are flying within 3 months and are on their own abou ...

... The Spaceguard program is sponsored and run by NASA Ames Space Science Division: Asteroid and Comet Impact Hazard. Also under the direction of Dr. Tom Gehrels the University of Arizona has the Spacewatch program. NEOs can be either asteroid or comets. Ninety percent of the information that I came across discussed asteroids. Therefore, I will concentrate on asteroids alone. I'm not fully knowledgeable on the subject but I did learn a great deal. What are NEOs? The "Webster's New World Dictionary" states, "Any of the small planets between Mars and Jupiter". The "Funk and Wagnalls Encyclopedia from Infopedia" states, "One of the many small or minor planets ...

... low pH water that has the ability to mobilize heavy metals contained in geological materials with which it comes in contact. "ARD causes a devastating impact on the quality of the ground or surface water it discharges to. (Ellison & Hutchison)" ACID MINE DRAINAGE Within the mining process there are several sources that cause ARD. No matter what activities occur, ARD usually occurs when certain conditions are met. These conditions are the factors that limit or accelerate the release of ARD. The initial release of ARD can occur anywhere from a few months to many decades after the sulfide containing material is disturbed or deposited. ARD has been associated wit ...

... of industrialized society. This " ozone shield is dissipating " and the cause is laid primarily to man - made chemicals ( Bowermaster et al, 1990, p.27 ). If enough of these man - made chemicals are released, " the ozone layer would be weakened to such an extent that it does not filter out the sun's invisible and dangerous ultraviolet rays " ( Jones, 1992, p.36 ). Such a scenario would drastically alter society and the environment. Ozone depletion has been described as " potential catastrophe " and " a planetary time - bomb " ( Way, 1988, p.9 ). The four main areas affected by a depleted ozone layer and thus by the corresponding increase in harmful ultraviole ...

... Hence, because there is two single strands of DNA, there will be two new daughter strands synthesized. However, each of these daughter cells is synthesized in different ways. The first strand of DNA is built by simply adding nucleotides to its end. This strand grows inward towards the replication fork as the DNA molecule unzips. This strand ends with a hydroxide (OH) group and is called the 3` prime or 3`end. The enzyme that catalyzes this process is called DNA polymerase. The second strand is built by having a polymerase jump ahead on the strand and fill in the complementary nucleotides backwards. This strand moves in the outward direction, hence away from ...

... which block the salmon's path back to their breeding grounds. The salmon go back to the same areas, just as their ancestors did, to lay their eggs. The hydropower plant's turbines are also very dangerous to young salmon. Many of them are killed by the giant turbines on their way back to the ocean. Killing off many of the salmons new generation. Pollution is also a killer of many Chinook salmon. Pollution caused by sewage, farming, grazing, logging and mining find it's way into our waters. These harmful substances kill many species of fish and other marine life. The Chinook salmon is no exception. The chemicals are dumped into the rivers and streams an ...
