.... 6- 12 tons. It had a short, pointed tail, a bulky body, column-like legs with hoof-like claws, and a bony neck frill rimmed with bony bumps. It had a parrot-like beak, many cheek teeth, and powerful jaws. WHEN TRICERATOPS LIVED: Triceratops lived in the late Cretaceous period, about 72 to 65 million years ago, toward the end of the Mesozoic, The Age of Reptiles . It was among the last of the dinosaur species evolve before the Cretaceous- Tertiary extinction 65 million years ago. BEHAVIOR: Triceratops was probably a herding animal, like the other Cartesians. This hypothesis is supported by the fining of bone beds, large deposits of bones of the same spec .....

.... are part of the life cycle of many species. Killing jaguars for protection and furs are ruining other species that live in the same range as them. These cats are of no harm to human life, most deaths that jaguars have had a part in were to protect themselves from being killed. Many jaguars just disappear from the pressures of being killed. While the animal is trying to change habitats they have died. The rain forests that the jaguars inhabit are being torn down to open up lumbering, farming, livestock raising, and other activities carried out by humans. Killing a jaguar is taking away a life that is doing no harm to the eco-system. A jaguars' way of .....

.... recombinant construction is introduced into a bacterial colonies all derived from a single original cell bearing the recombinant vector, in a short time a large amount of DNA of interest is produced. This can be purified from contaminating bacterial DNA easily and the resulting product is said to have been "cloned". So far, scientists have used genetic engineering to produce, for example: - improve vaccines against animal diseases such as footrot and pig scours; - pure human products such as insulin, and human growth hormone in commercial quantities; - existing antibiotics by more economical methods; - new kinds of antibiotics not otherwise available; - pla .....

.... seizures to problems in the brain. This view was not accepted by his contemporaries and was pushed aside. It was not until the late 1800s that people again began to understand that epilepsy was caused by a brain malfunction. Two European physicians, John Hughlings Jackson and W.R. Gowers, studied people with epilepsy at the National Hospital for Paralyzed and Epileptics in London and proved Hippocrates' theory that epilepsy is a brain malfunction. Still, the 19th century health care systems in Europe isolated people with epilepsy and forced them to live in colonies away from society. Until as late as the 1950ˇ¦s, people rarely talked about their epilepsy a .....

.... inches tall, do to the limited amount of cabin space that the Mercury modules provided. All who met these requirements were also required to undergo numerous intense physical and psychological evaluations. Finally, out of a field of 500 people who met the experience, training, and height requirements, NASA selected seven to become U.S. astronauts. There names, Lieutenant M. Scott Carpenter; Air Force Captains L. Gordon Cooper, Jr., Virgil “ Gus” Grissom, and Donald K. “Deke” Slayton; Marine Lieutenant Colonel John H. Glenn, Jr.; and Navy Lieutenant commanders Walter M. Schirra, Jr., and Alan B. Shepard, Jr. Of these, all flew in Project Mercury except Deke .....

.... there is saltwater, or seawater. Seawater consists of fifty- five percent chlorine, and thirty-one percent sodium (Groliers). It makes up approximately ninety-seven and two tenths percent of the total volume of the world's water, and covers more than seventy percent of the earth's surface (Groliers). Sea water doesn't just contain hydrogen, oxygen, sodium, and chlorine; it also contains every naturally occurring element. Although seawater has a fairly constant ratio of major elements, salinity and seawater can fluctuate. Normally, the salinity is thirty-four to thirty-seven parts per thousand (ppt.), but on a particularly rainy morning, the salinity may de .....

.... of lung cancer, farther reductions to lower levels may be too difficult or even impossible to achieve.(4) Radon enters buildings through: exposed soil in crawl spaces, through cracks, openings in floors, and through below grade walls and floors. This is the primary source of elevated radon levels in buildings.(5) Outdoor air contains radon, but it is in extremely low concentrations therefore it is not a health hazard. Some wells contain water that has radon dissolved in it. This can be a hazard if the water is agitated or heated, allowing the gas to escape and elevate the levels that are in the building.(6) Health Risk The Surgeon General's office rep .....

.... and infrastructures. Hurricane Gilbert, September 1998 was described by meteorologists at the US National Center in Miami, as the most intense western-hemisphere tropical cyclone on record. Large areas of Jamaica were devastated and the country’s Prime Minister, Edward Seaga, pronounce it the worst natural disaster ever to strike his country. Greatest loss of life however, occurred in Mexico where Gilbert hit twice, first of all traversing the Yucatan Peninsula and two days later making landfall some 150 km south of the border with the USA, finally dissipating near the city of Monterrey. During its most intense phase at the western end of the Caribbean .....
