... in the opposite hemisphere, because it is further away, and the rays from the sun are indirect. They are indirect, because of the earth’s round shape. If you would take all ball, and shine a flashlight on it, there is no way possible to get the light to spread evenly over the entire ball. This is just like Earth and the sun. The earth’s shape makes the light amount about even, for example, at 40%S and 40%N latitude because the rays sort of fan out from the equator. While the earth is revolving around the sun, it is also rotating on it’s own axis. One full rotation equals one day or twenty- four hours. At ...

... minor and usually never exceed 20 miles per hour. While slab are the destructive and deadly mountain slides. It is not uncommon for one of these to destroy a small town or forest. Since loose snow aren’t very dangerous, I will discuss slab . The fundamentals of how these snow masses occur, what to look for when testing and just all-together prevention. The basic chemistry behind a slab avalanche is when one layer of snow does not bond to the layer below it. Any kind of temperature change, fresh snowfall, the weight of a person, all can cause the slab to break free from the lower layer. The formation of a slab i ...

... the reader what the "Gallup poll" is, when it was taken and who produced it. Equally important, in the seventh paragraph Viscusi states that "cancer researchers" generally note. Again he fails to let the reader know the credentials of the cancer researchers. Another example of poor credentials is when Viscusi states some percentages in "a 1991 survey of company smoking policies". He again fails to let the reader know the credentials of the survey. Another explanation as to why Viscusi's article is not successful is because the organization is confusing. The thesis Viscusi is trying to prove is that the are exaggerat ...

... tiger has the fewest stripes. Tiger stripes are like human fingerprints; no two have the same pattern of stripes. The tiger's head often carries the Chinese mark of wang or king on the forehead. Most have an orange coat with dark brown or black stripes accented with white. that live in cold climates (Siberian ) have thicker fur than that live in warm climates. A tiger's tail is 3 to 4 feet long, about half as long as its body. use their tails for balance when they run through fast turns. They also use their tails to communicate with other . Where did tigers come from? Tigers (and all other carnivores) a ...

... century BC by Empedocles—that all things are composed of air, earth, fire, and water—was influential in . The Roman emperor Caligula is said to have instituted experiments for producing gold from orpiment, a sulfide of arsenic, and the emperor Diocletian is said to have ordered all Egyptian works concerning the chemistry of gold and silver to be burned in order to stop such experiments. Zosimus the Theban (about AD 250-300) discovered that sulfuric acid is a solvent of metals, and he liberated oxygen from the red oxide of mercury. The fundamental concept of stemmed from the Aristotelian doctrine that all thin ...

... customized DNA using these genes. They also learned about vectors, strands of DNA like viruses, which can infect a cell and insert themselves into its DNA. With this knowledge, scientists started to build vectors which incorporated genes of their choosing and used the new vectors to insert these genes into the DNA of living organisms. Genetic engineers believe they can improve the foods we eat by doing this. For example, tomatoes are sensitive to frost. This shortens their growing season. Fish, on the other hand, survive in very cold water. Scientists identified a particular gene which enables a flounder to resist ...

... peoples concerns. One aspect of that Nash doesn't necessarily address is the ethical issue. In his first paragraph, Nash writes of a world where humans can be cured of diseases that are currently life threatening. Where cells can be "cultivated in lab dishes" to help preserve human life. In the following paragraphs, he goes on to write about the "hasty legislation" that could possibly have negative long-term effects on the future of because of the bad wording going into some of the laws. Many are afraid that the rich and famous might take advantage of the opportunity to generate copies of themselves. Nas ...

... primarily responsible for the smoothness and firmness of young skin. Consequently, when these proteins breakdown, the skin will sag, and the muscle will lose its firmness. Another sign of passive aging is the breakdown of lipids at the biochemical level. As aging membranes leak during this lipid degeneration, a fatty, brown pigment known as lipofuscin accumulates. As this happens, the mitochondria, or the “powerhouse of the cell� begins to break down, thereby decreasing the amount of energy that is being supplied to the cell. This cellular degeneration may be set into action by highly reactive chemicals ...

... a young girl wants to have the confidence that it seems everyone else has. A. They may develop anorexia because they are dissatisfied with themselves. B. An anorexia will take drastic measures to change her body image in an attempt to fit in. An Conclusion: It has not yet been pin-pointed what the exact cause of anorexia is. Many factors play a role, including self-esteem. Children need to be showed love and caring in order to gain the appropriate levels of self-esteem.  Anorexia is a big issue in society today. Girls and boys are developing anorexic symptoms as young as age fiv ...

... with sedentary life-styles than those who engage in a daily brisk walk of 30 to 60 minutes (Cufman, 1993). Moderate regular exercise, lasting say 15 to 30 minutes, five times a week also has been found to improve health. In fact, high levels of exercise increase the risk of injuries (Edlin p.130 ). If you exercise regularly, your overall risk of a heart attack is about 50 percent less than if you are inactive and out of shape. With routine exercise you can reach a level of physical fitness comparable to an active person ten to twenty years younger. Regular exercise may also lower your cholesterol and blood pressure ...
