.... or depression.(CHADD) Gender and age affect the way the patients display their symptoms. Boys are more likely to have the disorder than girls. The symptoms of ADHD usually decrease with age, but those symptoms related with other similar disorders are said to increase with age. 30-50% of children with ADHD may display symptoms, although often times less severe, into adulthood. ADHD may be observed in children before the age of four, but it’s signs are often missed until the child begins school. ADHD is often accompanied by learning difficulties, excessive physical activity, i .....

.... the preservation of certain wildlife. NO DEFENSE Areas like Ontario, Canada, mainly southern regions that are near the Great Lakes, have substances such as limestone or other known antacids that can neutralize acids entering the body of water thereby protecting it. However, large areas of Ontario that are near the Pre-Cambrian Shield, with quartzite or granite based geology and little top soil, do not posses enough buffering capacity to neutralize even small amounts of acid falling on the soil and the lakes. Therefore over time, the basic environment shifts from an alkaline to a acidic .....

.... either an appetite loss or gain. is a recurrent illness, so a person usually has more than one episode. These episodes can last from weeks to months. They occur whenever and have no certain pattern. Sometimes a stressful life event can trigger an episode, and sometimes they just happen. If a person has more than four episodes a year they are known as “rapid cyclers”. This is more common in women. There is no exact reason for what causes , but some doctors say that it may be from imbalances of certain kinds of brain chemicals. Heredity also has a little part to do with it. .....

.... tissues. An analogy that fits very well with the study of the endocrine system is that of a message in a bottle. We can think of the body as a river, and a specific hormone may be a bottle containing a message. The organs or glands mentioned above would manufacture the “bottles” (hormones) that would be released into the river (blood stream). If there were no receptor sites for the hormones in the body, then they would continue to flow along the river and probably not make their destination. However, there are systems of receptor sites that enable specific hormones to bi .....

.... solution of hydrogen chloride. The activation energy of a particle is increased with heat. The particles which have to have the activation energy are those particles which are moving, in the case of magnesium and hydrochloric acid, it is the hydrochloric acid particles which have to have the activation energy because they are the ones that are moving and bombarding the magnesium particles to produce magnesium chloride. The rate at which all reactions happen are different. An example of a fast reaction is an explosion, and an example of a slow reaction is rusting. In any reaction, reactan .....

.... 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 is simply no believable evidence that has convinced me that UFO's could even possibly be real. To begin with lets examine just how UFO's and the big phenomenon came about. As we know man .....

.... other, or they give each other a grumpy grunt. Sometimes the two groups would even stay together, and then eventually separate. There are many rumors about gorillas being very violent, but there are no reports about it. There are times when they have little mock fights, but there is never any blood shed in them. Right now there are not too many you will find in the Virungas. Their population is only in the hundreds. In 1960, there was an estimated 450 gorillas still remaining in two isolated habitats. In a 1981 census, it gave a figure of about 254 gorillas. Right now there is .....

.... I been so wrong. Due to the nature of the injury, the doctor elected to stitch my cartilage back together. Because of the intricacy of the operation, I was restricted to non-weight bearing activities for three weeks. If I wished to return to wrestling, the doctor stated that I would have to demonstrate a muscle strength in my injured knee equal to ninety percent of my good one. When informed of this requirement, I could barely bend my leg twenty degrees nor use it to lift a ten-pound weight. One week after surgery and with the aid of crutches, I nervously entered the rehabilitation cli .....

.... variation in the course of the disease. Symptoms usually appear in individuals between the ages of 40-70, though the disease has been reported in both younger and older persons. Survival after the confirming diagnosis is, on average, two to five years. Progression of ALS varies with each individual; therefore, some will live longer--up to 10 years, and about five percent will exceed 12 years. In some cases, the disease seems to plateau. Many patients are able to live productive and satisfying lives especially with the use of assistive devices for daily living, and later in the disease, au .....

.... quickly converted into nitrates and nitrites by oxygen and water. Yet even its short-lived life, it has found many functions within the body. Nitric oxide enables white blood cells to kill tumor cells and bacteria, and it allows neurotransmitters to dilate blood vessels. It also serves as a messenger for neurons, like a neurotransmitter. The compound is also accountable for penile erections. Further experiments may lead to its use in memory research and for the treatment of certain neurodegenerative disorders. One of the most exciting discoveries of nitric oxide involves its function in .....
