.... eyes 6. The razor blade symbol signifies that you will be working with sharp objects. You should always be careful when working with sharp objects. 7. An electrical plug symbol means that you will be using electricity in your lab. Never touch an electrical socket or appliance with wet hands. 8. The symbol that looks like a duck means that you will be working with live animals. Analysis and Conclusion: 1. The person is not wearing safety goggles and he isn't really paying close attention. Safety goggles are vital when you are working with fire. 2. She is pointing the vial towards herself. Whenever you are working with heating liquids, the .....

.... fields have actually been reversed. Approximately 4.55 billion years ago, the Earth was just a ball of molten material. Since then, parts of the Earth have cooled forming the solid crust-mantle. This process has been occurring for roughly about 3.8 billion years. The mantle is about 2900 km. thick, which lies above a layer of molten magma that still exists today. The immense heat from the magma (approximately 2700(C) causes convection in the mantle (Figure 1). Convection is caused by non-uniform temperature in a fluid and density differences. This continuous convection is the cause of plate movement. Each complete cycle, called a c .....

.... ? There are many laws and regulations to keep our water clean. Such as proposition 65 "The safe drinking water and toxic enforcement act" of unsafe levels of chemicals known to cause cancer and reproductive harm into actual or potential water sources. There is also the Toxic Pits cleanup act of 1984. This act states that there is to be no discharge of hazardous wastes within an half a mile of a potential drinking water source. This is something being done, but water does travel and seep through ground so what is this act really doing. The clean water act is designed to protect ground water indirectly by protecting the quality of surface wate .....

.... you develop so that you can use it 'at will' in our present third dimensional reality. Teenagers are most wanting to develop and other higher skills such as telepathy, as they know they will use them in their lifetime. On an intuitive level they know we are shifting reality soon where this ability and others will be open to humans once again. Many of the 'star children' --those who remember that they are connected to other worlds and realities--will try to tap into their higher gifts. 'Patience' is the name of the game. As the planet is shifting now into 4th dimensional frequency you will soon get to use these powers and be able to control the .....

.... polar regions, which resulted in a chilling of the deep sea and, later in the Cenozoic Era, in widespread glaciation. Paleogene mountain-building events in western North America foreshadowed Neogene uplifts of such ranges as the Sierra Nevada and the Rocky Mountains. During the Neogene, the modern world took shape. The global ecosystems acquired their present configuration and prominent topographic features assumed the forms we are familiar with today. No mass extinction marked the transition from the Paleogene to the Neogene. During the 24 million years of the Neogene, however, life ad Earth’s physical features have changed signif .....

.... thick and humid forest growth. This type of physical region is located in the Congo Basin along the equator. It is important to understand the geology of Africa, because many of the diseases, which were born, had a lot to do with the climate and land region they were growing in. Africa has struggled with many different types of disease within their society due to their type of land, climate and weather. "Among all the diverse natural environments of the earth, tropical rain forests are the most variegated in the sense that more diverse forms of life share this kind of habitat than occupy drier, cooler regions."(McNeill,16) Africa possesses the .....

.... inherits all or part of an extra copy of chromosome 21. Trisomy 21, the inheritance of an entire third copy of this chromosome, accounts for 95 percent of Down syndrome cases. Two other abnormalities each account for 2 to 3 percent of all cases. The first, translocation, takes place when a child inherits an extra piece of chromosome 21 attached to a different chromosome. The second, called mosaic Down syndrome, results when only some cells in the body have the extra chromosome. There is no cure for Down syndrome although prenatal tests are available to identify fetuses with the disorder. Down syndrome can be diagnosed just by looking at the baby .....

.... by divine power, and that the above mentioned complexities could only be achieved by a Supreme Being. The age of Mars has been reported to be between 3.6 billion and 1.3 billion years old, "depending on who you ask" (Erjavec, 1). These ages come from the estimated ages of meteorites found on Earth that are believed to have originated on Mars (Meteorites from Mars, 1). The meteorites were dated using radiometric dating methods (Erjavec, 1). The most widely accepted theory of life on Mars is that of the recently conceived primitive, or microscopic, life may have existed on early Mars. "A NASA research team at the Johnson Space Center and at Stanfo .....

.... ozone layer is the only protection for life on Earth against deadly ultraviolet radiation from the sun. Once the ozone layer is completely destroyed, all life on Earth will cease to exist, killed by the deadly radiation. The planet will become a barren rock devoid of all life. Global warming is the predicted result of the greenhouse effect, created by so-called greenhouse gases, such as carbon dioxide and methane, in the atmosphere. The increase in these gases is thought to be caused by industrialization, especially by the use of fossil fuels such as coal and oil. These gases act much like the glass in the greenhouse: They let sunlight in and keep .....

.... the media did as well. Whatever the media says or mentions one breath of usually spreads so quick and gets so out of hand it is almost as unbelievable as a UFO being real. Another odd fact about UFO's is that if they are suppose to be out there somewhere why did the government stop research on them? Maybe they got tired of spending money on something that was getting them nowhere. The overall and main question that has been asked for many, many years is, "Are UFO's real?' This is simply one question that can not be answered with yes or no but only answered with opinion. My opinion as to whether or not UFO's are real would have to be no. There .....
