Rabbits

... their first three to four weeks. Although mature hares have longer ears than rabbits, both mammals rang from 18 to 26 inches (46 to 66 cm) in length and weigh as much as 26 pounds (12 kg). The hare is also noted for its ability to change its fur color gradually to blend into its surroundings. The arctic hare's fur turns completely white during the winter months. During the spring, as the snow melts, the hare grows a new coat of brown fur. Another hare that changes color is commonly called the snowshoe rabbit. The hare has strong hind legs that enable it to hop 43 miles per hour (69 km/h), as fast as a race horse. ...

Vortex, gradually turning the speed up. Heat in a water bath. Cool the tube. 2. Wet the dialysis tubing with the beaker of distilled water. 3. Twist one end of the tubing. 4. Fold the twisted end over on itself. 5. Tie a tight knot. Leave the extra string. 6. Insert the transfer pipette (cut off top) about one third of the way into the tubing. 7. Tie a knot securely around the transfer pipette. Leave the extra string. ...




Genetic Cloning ----

... size and are similiar to humans, also the availability of these organs is great due to the reproductive cycle of pigs. The biggest obstacle is the issue of rejection. The new organ is typically killed, even before the surgeon closes the incision, due to hyperacute rejection. This process clots the blood, by forming antibodies that attach to the endothelium of the blood vessels in the organ. The complement system creates gaps in vessels, allowing gaps to form and clots to accumulate. Therefore, a complement inhibitor was developed as the gene was cloned, introduced into pigs whose cells produced this protein. Anoth ...




Fetal Alcohol Syndrome

... losses. FAS is considered the most common known cause of mental retardation in the Western World. For a positive diagnosis of FAS, in addition to a history of maternal alcohol use during pregnancy, each of the following three categories must be present: 1. slow growth before and after birth including weight, height and/or head circumference, 2. facial dysmorphology such as thin upper lip, flattened philtrum, and/or short openings between eyelids, and 3. damage to the central nervous system. Diagnosis can be difficult because many of the critical diagnostic features change with age. It is most difficult to di ...

... him. According to the legend, he has been growling and spitting fire ever since. Aristotle believed that "mild were caused by wind escaping from caves within the bowels of the earth and severe shocks were by gales that found their way into great subterranean caverns" (Matthys 87). However, with modern technology we found that what actually causes is tectonic plates which on average move only two inches per year they are driven by convection currents which is the upward movement of heated particles rising from the earth's molten core. As the plates are driven against each other one will try to and eventually ...




Satellites

... Tsiolkovsky and the experimental work of the American Robert Goddard, confirmed that a satellite might be launched by means of a rocket. During the years 1943 through 1946 several studies concluded that available rockets would be unable to place a satellite into orbit. Work on rockets for missiles and upper atmosphere research was so great after World War II that by 1954 the possibility of launching a satellite was no longer in serious doubt. In October 1954 the Committee for the International Geophysical Year (IGY), announced to other countries that they were considering launching small satellite vehicles for spac ...

... (later to be found to have hypothyroidism) and what he referred to as "Mongoloids." Down based this unfortunate name on his notion that these children looked like people from Mongolia, who were thought then to have an arrested development. This ethnic insult came under fire in the 1960s from Asian genetic researchers, and the term was dropped from scientific use. Instead, the condition became called "Down's syndrome." In the 1970s, an American revision of scientific terms changed it simply to "," while it still is called "Down's" in Europe. There are three main types of . The vast majority of children with (appr ...

... they are also rotating on there own axis. This movement causes an attraction or repultion from the electrons that are unpaird. They are moving in two directions though causing a negative and positive charge. In the case of magnatism though we find that these elements have a lot of unpaired electrons, in the case of iron, Fe, there are four. What happens then in the case of a natural magnet the unpaired electrons line up or the magnet in a specific mannor. That is all the atoms with unpaired electrons moving in a direction which causes a certain charge are lined up on one side and all the atoms with the oppo ...

... 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; - plants w ...




Ebola Virus

... to deal with problems like overpopulation and poverty, we may end up looking back nostalgically on the late twentieth century as a time of health and tranquility. As we show you, in the world of viruses, we are the invaders (Baddorf, Ourworld.compuserve.com)." Between the years of 425BC-430BC Athens' population was dramatically reduced when about 300,00 of its inhabitants died from some sickness. Some people now believe that this great plague was really Ebola. The first recorded outbreak of the Zaire string of the Ebola virus was in Zaire, in 1976. The doctors didn't know how to treat it and that meant tha ...
