.... into many different parts called organs. All of the parts are controlled by an organ called the brain, which is located in the head. The brain weighs about 2.75 pounds, and has a whitish-pink appearance. The brain is made up of many cells, and is the control centre of the body. The brain flashes messages out to all the other parts of the body. The messages travel in very fine threads called nerves. The nerves and the brain make up a system somewhat like telephone poles carrying wires across the city. This is called the nervous system. The nerve .....

.... Warren has proposed the following criteria for "person-hood": 1) consciousness (of objects and events external and or internal to the being), and in particular the capacity to feel pain. 2) reasoning (the developed capacity to solve new and relatively complex problems) 3) self-motivated activity (activity which is relatively independent of either genetic or direct external control) 4) the capacity to communicate, by whatever means, messages of an indefinite variety of possible contents, but on indefinltely many possible topics. 5) the presence of self-concep .....

.... for several weeks with various symptoms such as bodily soreness, fever, bronchial complications, and even pneumonia. But while these conditions can be painful and frightening, we are usually confident that proper medication and rest will take care of the matter. However there is a much more severe and indiscriminate tyrant, with enormous corrupting influence, capable of infiltrating all of civilization.

.... After fiddling with the sticks for an hour or so, Sultan happened to align the sticks and in a flash of sudden inspiration, fitted the two sticks together and pulled in the banana. Kohler was impressed by Sultan's rapid “perception of relationships” and used the term insight to describe it. He noted that such insights are not learned gradually through reinforced trials. They seemed to occur in a flash when the elements a problem are set up appropriately. In another experiment boxes were put in a room with a banana hanging from the ceiling. The chimps f .....

.... basis of exotoxin structure, function, and action have been clearly established. Consequently, highly effective methods of treatment and prevention of diphtheria have been developed. The study of Corynebacterium diphtheriae traces closely the development of medical microbiology, immunology and molecular biology. Many contributions to these fields, as well as to our understanding of host-bacterial interactions, have been made studying diphtheria and the diphtheria toxin. Hippocrates provided the first clinical description of diphtheria in the 4th century B.C. .....

.... same needle, they have a high risk of catching the virus. The third most common way AIDS is spread is by blood transfusions. This is done almost the same way as by IV needle but it is always by the blood.(Madaras,187) The most rare way the AIDS virus is spread is by a mother passing it to fetus inside her.(Madaras,188) AIDS is a very rapidly-spreading disease although it is only spread four ways. Ten years ago only two cases of AIDS were known. Nine years ago only seven cases were known. In 1983 over 3,000 cases were recorded, and by 1989, there were more .....

.... levels of education, and people with a lower socioeconomic status. From a standpoint of age, gonorrhea is most common in people 15-29 years of age. Risk factors include having multiple sexual partners, a partner with a past history of any STD, and unprotected sex (sex without the condom or the newly developed female condom). The early symptoms of gonorrhea are often mild, and many women who are infected have no symptoms of the disease. Symptoms of gonorrhea usually appear within two to ten days after sexual contact with an infected partner, although a sm .....
