... scientists are concerned that changes in the variable contents of the atmosphere--particularly changes caused by human activities--could cause the Earth's surface to warm up to a dangerous degree. Since 1850 there has been a mean rise in global temperature of approximately 1° C (approximately 1.8° F). Even a limited rise in average surface temperature might lead to at least partial melting of the polar icecaps and hence a major rise in sea level, along with other severe environmental disturbances. 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-covere ...

... a scientific genius and ambitious in his studies. When he tried to use his genius to prolong life, he found he had the power to create life. The doctor's scientific success in creating the monster was ultimately a failure for morality. Frankenstein, upon completion of his monster, realized the immorality of his work and rejected it and disassociated himself from it and science. The result of Frankenstein's immorality was death for just about everyone he loved and utter despair for himself. The monster was not necessary for our future and neither were the methods of his creation. Because of the doctor's irresponsibility, he lost everything including his life ...

... your child to be “perfect”. Over the years, there has been heated, ethical controversy on each of these issues, especially designer babies. How far will we let biotechnological discovery take us? What will come of the world if designer babies become standard procedure? The earliest and maybe simplest use of genetic manipulation was in the selection of the sex of an unborn child. In Vitro Fertilization(IVF - A procedure in which a woman’s eggs are removed from her body, fertilized outside using sperm from her husband or another donor, and then transferred back to her body.) was originally limited to couples that were infertile. Ev ...

... Rain has been known to reach the acidicy of pH 2, ( battery acid has a pH if 1 ) this is a drastic change, as normal rain is average pH 5.2. Acid Rain can dissolve limestone and chalk, and corrodes outdoor structures. Statues and monuments that are left unprotected can fall victim to the unpredjudiced destruction of acid rain. Acid Rain reacts to different types of soil and rocks in two ways. 1) Acid rain will dissolve alkaline rocks and soil, or will neutralize the alkalinity. 2) Acid rain will increase the acidicy of already acidic rocks and soil, such as granite, or the soil which results from corroded granite. Acidic chemicals, an ...

... is surrounded by a membrane. In between the membrane of the nucleus and the cell membrane is cytoplasm. It is in the cytoplasm where all of the other organelles are stored. There are six main organelles in the cytoplasm. First, the mitochondria, which provides energy to the cell through ATP and respiration. Then there is the endoplasmic reticulum which separates parts of the cell. Then there is the Golgi apparatus which is used for sorting, storing, and secretion for the cell. Next are lysosomes, which hydrolyze macromolecules. Then there are centrioles that play a major role in cell division. And lastly there are vacuoles which have a variety of storage f ...

... on our primitive Earth in a sealed glass ecosystem. This ecosystem had a bulb, which contained an amount of water with hydrogen, nitrogen, and simple carbon compounds dissolved in them. These various elements were believed to either formed with the Earth or were picked up by the many meteoric collisions that immediately following the formation of our planet. The bulb had a heating unit under it to stimulate evaporation, then there was a smaller bulb that contained electrodes, simulating lightning and other static discharges, the evaporated water and gasses rose into this electrified bulb and were occasionally energized. The vapor then flowed into a condenser ...

... the rock can be estimated. In the case of inorganic and older rocks, Carbon 14 would not be a good choice because of its short half life. Uranium, which is known to have a much longer half life would be a good alternative. If a pound of the metal Uranium is left to decay, it would take approximately 4.5 billion years for it to turn into half a pound of Lead ( Howter, 1996, Radiometric Dating: An Exercise in Faith). As it turns out, this is what scientists believe to be. The assumption that the earth is 4.5 billion years old has raised doubts in the minds of some skeptics who question the accuracy of the data used in radiometric dating! They claim that without know ...

... transfer improves (Hawley, 1998). Nuclear transfer takes the nucleus of a cell from one individual and places it in the egg or another individual, from which the nucleus has been removed (Wertz, 1998b). The change in phenotype, the observable physical and biochemical characteristics of an organism, of livestock is accomplished by bombarding embryos of livestock with genes that produce “super” livestock traits; however, this technique is not efficient because only five percent of the offspring express these “super” traits that would guarntee a more productive industry. Scientists can easily genetically alter adult cells; therefore, cloning from an adult cell wou ...

... in the clouds where sulfur dioxide and nitrogen oxides react with water, oxygen, and oxidants. This forms a mild solution of sulfuric acid and nitric acid. Sunlight increases the rate of most of these reactions. Rainwater, snow, fog, and other forms of precipitation containing those mild solutions of sulfuric and nitric acids fall to the earth as . Water moves through every living plant and animal, streams, lakes, and oceans in the hydrologic cycle. In that cycle, water evaporates from the land and sea into the atmosphere. Water in the atmosphere then condenses to form clouds. Clouds release the water back to the earth as rain, snow, or fog. When water droplets ...

... more. The common protocol is Transmission Control Protocol (TCP/IP). TCP/IP is the protocol of the Internet. Internet is actually the short form of the word Internet work. Internet work means a network of networks. At one time, all of the different networks used different protocols. A user could talk to others on their network, but not to someone on a different network. The protocol TCP/IP solves this problem. It is what allows a person on one network to communicate with a person on a different network. When I mentioned something to share in the network definition, it can be anything, an idea, document, or greeting. Networking allows use of applicati ...
