.... Typing is used by taking semen off the body of clothes then amplifying the genes. The machine that copies the DNA is called the PCR. The DNA is then cut and placed the wells in trays. PCR copies the small pieces of DNA. It is performed by a blotting process. This process has 21 different catogories. Other tests include those for tracing genetic diseases within families, finding the genes that cause genetic diseases. DNA Typing can also prove the relationship with families. DNA Typing is becoming more common than ever. This process is helping to free convicted people of crimes they may not have committed by taking samp .....

.... apparently be in more than one place at the same time, in which a particle can penetrate a barrier without breaking it, in which something can be both a wave and a particle, and in which widely separated particles can cooperate in an almost psychic fashion, is bound to be both thrilling and bemusing. Niels Bohr, one of the founders of the theory, once remarked that anybody who is not shocked by quantum mechanics hasn't understood it. For decades the complexity and incredibility of the quantum world was an obstacle to the theory being known outside the scientific community. Then in the 1970's a number of writers recognized that th .....

.... waste land without its natural greenhouseing. There are a collection of gases called "greenhouse gases," which are water vapor, carbine dioxide, ozone, methane, nitrous oxide, and chlorofluorocarbons (CFC). Without the natural greenhouse effect, the surface temperature of our planet would be an average of -18°C (zero degrees F). The mixture of these gases have remained pretty much stable over the centuries and have kept us all living. But here we are in the late nineties, and we are not so stable anymore. Our activities and what we use to perform our activities is increasing year to year, many of them doubling and tripli .....

.... scientists that our brain size grew over time as were evolved into making complex tools and we became increasingly sophisticated. The human skull is slightly different from that of our primate ancestors, these changes occurred over thousands of years of evolution. Over time the humans skull and teeth have decreased from that of our ancestors. The chimp has much larger canine teeth and a protruding jaw line. A similarities though can be seen on how uniform the layout of teeth are between the humans and chimps, both possess canines, premolars, and molars. Other notable similarities between us and the primates, specifically the c .....

.... author of a piece called “Animal Experimentation” in the book Intervention and Reflection displays and evokes the actual suffering of many harmless animals. "In 1953 R. Soloman, L. Kamin, and L. Wynne, experimenters at Harvard University, placed forty dogs in a device called a 'shuttle box,' which consists of a box divided into two compartments, separated by a barrier. Initially the barrier was set at the height of the dog's back. Hundreds of intense electric shocks were delivered to the dogs' feet through a grid floor.... they then blocked the passage between the comp .....

.... potent hallucinogenic drug known. Small doses of (1/2 - 2 ug/kg body weight) result in a number of system wide effects that could be classified into somatic, psychological, cognitive, and perceptual categories. These effects can last between 5 and 14 hours. Table 1: Effects of 1, 2, 3 Somatic Psychological Cognitive Perceptual mydriasis hallucinations disturbed thought processes .....

.... situation (O'Keefe, 1983). Indeed, this situation does not require the rat to have a concept of absolute space; it may depend on associations between cues and responses which are provided by the maze structure itself. However, O'Keefe & Nadel (1978) identified spatial behaviours which they argued would require the existence of an allocentric map: detection of changes within the environment; navigation to the goal from a different starting location; and perhaps most importantly detour behaviour, which required the adaptation of novel behaviour to find the goal after the usual route had been blocked in some way. Further support .....

.... produce complete plants. Grafting is another method of cloning used in Horticulture. Matching cuts are made in the stems of two plants, which are then fitted together so that their transport systems are in contact. The wounded area heals, and the two stems become a single physiological unit. All the McIntosh apple trees now in use and many other fruit varieties have been derived by grafting from single ancestral trees. "Nuclear transplantation," in which nuclei from cells of one individual are transferred to unfertilized eggs whose nuclei have been removed, is one method of artificial cloning in animals. All the transplanted nuclei .....

.... by their six or seven pairs of gill slits, there sharks can often be found in deep water. The frilled shark (CHLAMYDISELACHUS ANGUINEUS) who's appearance is quite unmistakable due to it's "eel" like appearance, is perhaps one the strangest shark that exist today. FOSSIL RECORD: Shark fossil record is fargmentery at best. Most fossils found so far consist of nothing but teeth in some cases a few vertebra have been found. This is rare due to the fact that sharks have bones instead, they have cartiladge which countrary common belief is rather solid. In the rarest of cases complete fossil have been discovered. Scie .....

.... damages the trees through the soil by releasing metals that harm them even further (Lucas, 72). Acid rain makes the trees lose their leaves, so when the trees try to regrow their leaves, buds come instead, this process is called a panic shoot (M. 15). Large land areas which used to be covered with forests are now gone, dead or dying (Baines, 21). Around the 1980’s more than half Kotto 2 of the trees in Germany had signs of acid rain damage (Edmonds, 14). Now it is known that acid rain is one of the biggest contributing factors in the death and deterioration of nature. .....
