.... more than four feet long. This shark is commonly seen inshore. 3. Smooth hammerhead (Sphyrna zygaena)-Bronze with dusky fin tips, it can grow to thirteen feet. 4. Great hammerhead (Sphyrna mokarran)-Attaining a length of a possible 18 feet, this is the largest and most dangerous of all the hammerheads. One of the most interesting things about the hammerheads is the unique shape of their heads. Ever since scientists started to study the hammerhead they have speculated about the use of the hammer. The hammer is a complex structure and probably serves more than one fun .....

.... are free transfer RNA [tRNA] molecules which hve three protruding bases these sets of three on the tRNA are called anti-codons. Each tRNA molecule attracts different amino acids, of which there are around twenty, and they "stick" to the tRNA and depending on which tRNA molecule it is it wil attract a diferent amino-acid.On the RNA every three bases are called codons these are complementary to the anti-codons of the tRNA. For instance a codon of - GAA - would pair with the anti-codon- CUU -. In this fashion weak hydrogen bonds form between the tRNA and RNA molecules. This occurs .....

.... on earth. I do see the possibility that maybe other solar systems is our solar system in history which is an interesting thought. Just because NASA has found a single cell living creature in a meteorite doesn't prove anything in my mind. Especially because of the fact that it has been on earth for 12 years when over this time the cell could have attached itself to the meteorite. Nobody knows enough about the subject to start telling the public that this is true, they should have never released it unless it were defiantly proven to be fact. NASA has a big name in the world, .....

.... organ, and replace it with the damaged one. The report on the cloning of the human's morphine receptor is advantageous to us because this helps scientists to develop new analgesics. The third section of the paper contains a brief discussion about the advantages and the disadvantages of genetic cloning. It speculates how our future will improve due to the technologies we are developing, and also the biggest drawbacks which might come from it. The last part of the paper, is the explanation of complicated terms used in this paper. The terms which will be explained are pri .....

.... humans as well. There has been much controversy on whether or not the cloning of humans as well as animals is ethical or even moral. Also there has been much discussion as to whether or not the benefits of cloning outweigh the dangers. WHAT ARE THE BENEFITS IN CLONING RESEARCH? There is no doubt that Dr. Wilmut's new discoveries have brought an uproar of excitement between not only the scientific community, but the general public as well. Groups such as farmers, surgeons and even environmentalists have shown various interests in cloning research. The farming communi .....

.... of epidural anesthesia in labor issues that are seldom discussed prenatally. Several factors make the use of epidurals potentially hazardous. The Physician’s Desk Reference cautions that local anesthetics – the type used in epidurals – rapidly cross the placenta. When used for epidural blocks, anesthesia can cause varying degrees of maternal, fetal, and neonatal toxicity which can result in the following side effects: hypotension, urinary retention, fecal and urinary incontinence, paralysis of lower extremities, loss of feeling in the limbs, headache, backac .....

.... an analog signal, to travel over the telephone lines. Once it gets to its destination, the data is converted back into its digital form. Line noise is a result of data being transmitted as an analog signal. The FCC imposed limitations, decades ago, to minimize the amount of line noise that was allowed. This law was imposed long before the PC ever existed. However, it directly affects how fast we can access the Internet today, at speeds of only 53kbps. Even that connection speed is theoretical. Depending on the quality of the telephone lines that run into your home, your .....

.... any way or form it will have a large impact on the growth or the preservation of certain wildlife. Areas in Ontario mainly southern regions that are near the Great Lakes, such substances as limestone or other known antacids can neutralize acids entering the body of water thereby protecting it. However, large areas of Ontario that are near the Pre-Cambrian Shield, with quartzite or granite based geology and little top soil, there is not enough buffering capacity to neutralize even small amounts of acid falling on the soil and the lakes. Therefore over time, the basic environm .....
