.... this experiment 26 dogs died. One of the deaths occurred during an epileptic seizure; another from brain hemorrhage. Other dogs, before death, became feverish and anemic, lost their appetites, and had hemorrhages. The experimenters compared their results to those experiments conducted at the University of Utah and the Argonne National Laboratory in which beagles were injected with Strontium 90. They concluded that the dose needed to produce “early death” in fifty percent of the sample group differed from test to test because the dogs injected with Strontium 90 r .....

.... I never knew that some kinds of birds were in danger. We can help these animals and plants by making laws that you are not allowed to hunt or kill any animal that is in danger of extinction. Government Involvement Only since the 19th century has there been worldwide concern about the case of species in their natural environments. Finally in 1916 they made a law called Migratory Bird Treaty. They had this law in United States, Great Britain, Canada, and later in Mexico. This law was made so that people can not kill animals that are endangered. This la .....

.... famous women. The largest crater is named crater Mead. Almost all of Venus has volcano rock on the surface. There is over 100,000 volcano’s and they dot the surface. One flow out of a volcano is over 4,300 miles long. Venus was the first planet to be reached by a space probe. The space probe Mariner 2 flew close to Venus that sent information to Earth. The Mariner 2 was from the United States. A space probe from the Soviet was called the Venera 7. It was the first probe to land on Venus. When it landed it stopped working because the temperature was so hot. .....

.... deprivation). During the exchange of gases in the normal breathing process, the blood stream absorbs oxygen from air in the lungs, while carbon dioxide passes from the blood to the air. When you hold your breath, the exchange of gases slows, as "stale" air in the lungs is no longer replaced by "fresh" air. Oxygen is actually removed from the blood stream during the exchange of gases. depending on how completely oxygen is replaced by helium, you may lose consciousness quickly and without warning - you may literally pass out while still standing. The usual .....

.... The atoms were slowed to the low velocity by using laser beams. The hardware needed to create the BEC is a bargain at $50,000 to $1000,000 which makes it accessible to physics labs around the world. The next step is to test the new phase of matter. We do not know yet if it absorbs, reflects,or refracts light. BEC is related to superconductivity and may unlock some mysteries of why some minerals are able to conduct electricity without resistance. The asymmetrical pattern of BEC is is thought by some astrophysicists to explain the bumpy distribution .....

.... forward curve to the lower spine. The legs of a person with almost always become bowed and the elbows often cannot be straightened completely. Sometimes the person has limited twisting ability at the elbows. The hands are short, and the feet are short and flat. Another sign is double jointedness, caused by loose ligaments in some joints. Achondroplastic children can flex their finger, wrist, hip, and knee joints to an extreme degree because of this. These signs are usually apparent at birth, and can be diagnosed at that time. Affected men aver .....

.... our era, such as heart disease, cancer, stroke, AIDS and birth defects." He goes on further to say that animal experiments can not only mislead researchers but even contribute to illnesses or deaths by failing to predict any toxic effect on drugs. The majority of animals in laboratories are used for genetic manipulation, surgical intervention or injection of foreign substances. Researchers produce solutions from these animal "models" and are adapting them to human conditions. Unfortunately, these animal "models" can't always be connected with the human bod .....

.... increasing the average heat levels. Scientists predict that the average temperature will rise 1.6 – 6.3°F by the year 2100, which could wreak havoc with climates around the world. Why are greenhouse gas concentrations increasing? Scientists generally believe that the combustion of fossil fuels and other human activities are the primary reason for the increased concentration of carbon dioxide. Energy burned to run cars and trucks, heat homes and businesses, and power factories is responsible for about 80% of society's carbon dioxide emissions, about 25% of .....
