.... feelings of sadness and despair that can become feelings of hopelessness and helplessness. Some of the symptoms of a depressive episode include anhedonia, disturbances in sleep and appetite, psycomoter retardation, loss of energy, feelings of worthlessness, guilt, difficulty thinking, indecision, and recurrent thoughts of death and suicide. The manic episodes are characterized by elevated or irritable mood, increased energy, decreased need for sleep, poor judgment and insight, and often reckless or irresponsible behavior. Bipolar affective disorder affects approximately one percent of the population (approximately three million .....

.... by their larger size, the separation of nucleus from cytoplasm by a nuclear envelope, the association of DNA with histone proteins and its organization into a number off distinct chromosomes, and complex organelles, among which are chloroplasts and mitochondria. Scientists believe that eukaryotic organisms such as the protists evolved from the prokaryotes. There are two main theories which describe how this transition may have occurred. The first is the endosymbiotic theory, or enosymbiosis, and the other is the autogenous theory, or autogenisis. These two theories are not mutually exclusive, meaning one or the other could account for .....

.... extremely different. Medical departments see cloning as a way of providing needed organs such as the heart and lung. Doctors might also view cloning as a way to find cures for diseases such as aids and cancer. Should people be created for the purpose of dying? Many people believe it is unjust to use animals for testing various products for humans, such as makeup and shampoo. Creating life for the simple purpose of injecting a deadly disease in the body to find a cure is just? Another purpose of cloning may be for work labor. Should society create people to work for others like robots? People have different beliefs to answer such questions. .....

.... electrons as there are protons, so, on the whole, it is electrically neutral. The electrons have discrete kinetic energy levels, which increase with the orbital radius. When atoms bond together to form a solid, the electron energy levels merge into bands. In electrical conductors, these bands are continuous but in insulators and semiconductors there is an "energy gap", in which no electron orbits can exist, between the inner valence band and outer conduction band [Book 1]. Valence electrons help to bind together the atoms in a solid by orbiting 2 adjacent nucleii, while conduction electrons, being less closely bound to the nucleii, are free .....

.... and vegetable processing wastes, the explosives become broken down into harmless chemical forms. The Army is using composting to clean up munitions processing wastes at several of its ammunition plants, including ones in Louisiana, Wisconsin, and Oregon. At the Oregon site, composting is projected to save 2.6 million dollars compared with incinerating the contaminated soils. In addition to saving money, composting will also avoid the need for burning fossil fuels and will produce an end product usable for backfilling, landscaping, or erosion control. Introduction Whether people know it or not explosives, such as tnt, are a very importa .....

.... of vitamin C, 400 IU of vitamin D, more than 2000 mg of potassium, 2000 mg of sodium, 65 g of protein, 1.5 mg of thiamin, 1.7 mg of riboflavin, 20 mg of niacin, and 18 mg of iron. Nutritionists of today simplify this into an equation of 40% carbohydrates, 30% fats, and 30% protein that the entire day’s meals should be divided into. The total calorie intake must increase for active persons from 2200 to 2200 plus the total number used while exercising. This will ensure replenishment of the body’s system. With the wide variety of athletic competitions, the specific meal a competitor may need to eat to benefit themselves differs .....

.... O R-C-O-R’ + NaOH ---- R-C-O-Na+ + R’OH Ester(fat) + base(caustic soda) ---- salt of fatty acid(soap) + alcohol(glycerol). Caustic potash (potassium hydroxide) can be used instead of caustic soda (sodium hydroxide)but is more expensive. The base used to come from wood ash containing potassium carbonate which formed potash as this was not plentiful it made soap a luxury. The cheapest source of the ester is animal and vegetable fats and oils. H-H-H-H-H-H-H-H-H-H-H-H-H-H-H O H-C-C-C-C-C-C-C-C-C-C-C-C-C-C-C-C-C H-H-H-H-H-H-H-H-H-H-H-H .....

.... it was analyzed. The jury determined that the samples were contaminated because of the way they were handled. DNA Typing is not perfect. There are many loop holes in it. An example is the O.J. Simpson trial. During the process the DNA may be tampered with or damaged. In most rape cases DNA 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 .....

.... mixture) forms, on cooling, a stiff gel in which the molecules of the continuous phase are trapped in the holes of a "brush-heap" like structure of the gelatin. Administered orally. Microemulsion: Microemulsions are thermodynamically stable, optically transparent, isotropic mixtures of a biphasic oil-water system stabilized with surfactants. The diameter of droplets in a microemulsion may be in the range of 100 A to 1000 A. Microemulsion may be formed spontaneously by agitating the oil and water phases with carefully selected surfactants. The type of emulsion produced depends upon the properties of the oil and surfactants utilized. O .....

.... The tail alone is about 4 feet long. The kangaroo has a small head with large ears and a small mouth. The fur is soft and woolly and some can have stripes on them. The kangaroo's body is specially built for jumping. It has two long, powerful hind legs with four toes on each. The front legs are short and have five toes with claws. These paws are used to handle food. Most of it's weight it in the hind legs and tail. Kangaroos can jump across flat land up to thirty miles an hour. Even though it is quite timid, kangaroos can fight very hard. They use there paws to position an opponent, and then kick them with the powerful back legs. .....
