.... a solar furnace, which acts on the same principles as a large magnifying glass. The solar furnace takes the sunlight from a large area and by the use of lenses and mirrors can focus the light into a very small area. Very elaborate solar furnaces have machines that angle the mirrors and lenses to the sun all day. This system can provide sizeable amounts of electricity and create extremely high temperatures of over 6000 degrees Fahrenheit. Solar energy generators are very clean, little waste is emitted from the generators into the environment. The use of coal, oil and gasoline is a cons .....

.... the color of the skin or fur blends with the animal’s natural surroundings. In others there is great contrast with the natural surroundings to favorvisual signals that provide information about theidentity of a species, and about the gender, age, orsocial status of an individual. The skin also functions as a sensory and excretory organ and contains specialized glands. Mammary glands, which are present in fully developed form in all adult female mammals. Aquatic mammals, such as whales, dolphins, and sea cows, have no sweatglands. Sweat glands are usually located at the base o .....

.... help us to teach and practice new surgical techniques to doctors who perform today's delicate cardiac, ear, eye, pulmonary, brain surgeries, and other live saving surgery's. And most people faced with their death would rather live even if it meant killing animals. Next, animals help other animals as well. Veterinarians must learn the surgical techniques first so they can perfect their skills before they use them on other animals. Drugs for animals also use animal research to find cures for animal disease. Of course there are ways to avoid using animals in research. The way .....

.... In the United States, the Texas leaf-cutting ant, Atta texana , occurs in Texas and Louisiana. This ant is believed to cause a total yearly loss of $5 million in the United States (unison services. 1998). There are about 9,500 named species of ants. These ants are divided into 16 sub families and 300 genera, all which belong to the family called Formicidae, the family of ants (Hoyt. 1996). The leaf cutting ant belongs to the genus called Atta. There are fifteen different species of Atta and all are limited to the new world (Holldobler & Wilson, 1994). The leaf-cutter ant looks pretty much l .....

.... advancement in today’s world. Among these is the , which involves the research and support of Physical Mapping and DNA Sequencing. This would enable Humans to reproduce babies that what most parents want. Completing this DNA sequencing and Physical mapping would enable us to change everything in a new born baby to the likes of the parents e.g. IQ, Color, Strength, looks, gender, etc. The Human (HGP) is a research program for analyzing the structure of the Human DNA. This is achieved by determining the location of the one hundred thousand genes, and finding the sequence of 3 bill .....

.... found within the cell bodies of nerve cells in the cerebral cortex, and take on the structure of a paired helix. Other diseases that have "paired helixes" include Parkinson's disease, Down's syndrome, and Dementia Pugilistica. Scientists are not sure how the paired helixes are related in these very different diseases. Neuritic Plaques are patches of clumped material lying outside the bodies of nerve cells in the brain. They are mainly found in the cerebral cortex, but have also been seen in other areas of the brain. At the core of each of these plaques is a substance called amyloid, an abn .....

.... ore reserves, grade, type of ore, and the location. In order to mine, many months and millions of dollars have to spend in construction. There are only a few mines are discovered in convenient places, this costs a lot on transportation and labor on such an atmosphere. Construction includes food, health, accommodation and recreation facilities for the hundreds of working man. Water, power, communication, equipment, etc… So in a construction site is almost the same as a little empire. In able to build this, the Industry Company has to make sure the ore they are getting is worth it. Env .....

.... like this shows obvious intermediates for every major structural change, and the fossils occur roughly (but often not exactly) in the expected order. However, usually there are still gaps between each of the groups. Sometimes the individual specimens are not thought to be directly ancestral to the next-youngest fossils (e.g. they may be "cousins"" or "uncles" rather than "parents"). However they are assumed to be closely related to the actual ancestor, since the have similar intermediate characteristics. Where Does It All Begin ? Mammals were derived during the Triassic Period ((from 24 .....

.... to steroids more often because they're cheaper then marijuana or cocaine. A ten week cycle of testosterone cypinate and methandrostone costs only about one hundred dollars. Steroids are also very hard to trace because of their water base composition. They can pass through the body within two days. All these benefits of steroids help an athletes become more competitive and increase their chance of being a winner. Of course everybody wants better biceps and triceps but when using steroids to achieve this goal there is a large price to pay. However, steroids should remai .....

.... that all human beings are equal; but even more firmly, we are taught to believe each one of us is unique. Is that idea undercut by cloning? That is, if you can deliberately make any number of copies of an individual, is each one special? How special can clones feel, knowing they were replicated like smile buttons. "We aren't just our genes, we're a whole collection of our experiences," says Albert Jonsen. But the idea, he adds, raises a host of issues, "from the fantastic to the profound." When anesthesia was discovered in the 19th century, there was a specu .....
