.... is dissipating " and the cause is laid primarily to man - made chemicals ( Bowermaster et al, 1990, p.27 ). If enough of these man - made chemicals are released, "the ozone layer would be weakened to such an extent that it does not filter out the sun's invisible and dangerous ultraviolet rays " ( Jones, 1992, p.36 ). Such a scenario would drastically alter society and the environment. Ozone depletion has been described as "potential catastrophe " and " a planetary time - bomb " ( Way, 1988, p.9 ). The four main areas affected by a depleted ozone layer and thus .....

.... This is due to the fact that the moon has no atmosphere. Therefore, air resistance doesn't exist on the moon. Also, the amount of air resistance on an object depends on the speed, size, shape, and density of the object. The larger the surface area of the object, the greater the amount of air resistance on it. This is why feathers, leaves, and sheets of paper fall more slowly than pennies, acorns, and crumpled balls of paper. There is another legend that states that when Newton was lying against a tree in an orchard, he was struck on the head by an apple. He won .....

.... + 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-H-H-H O-Na+ This is a .....

.... of artificial cloning used in plant breeding, cells are cut from a plant and placed in a flask with a nutrient medium. The cells grow and divide, forming embryonic tissues that are transferred to soil, where they 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 .....

.... was a beautiful sunny day. The wind was gusting enough to pull my hair back, and I was admiring the palm trees, coconuts, and lizards near the Gulf of Mexico. The first few days were nice, but little did I know that I would soon be caught in the middle of a twister. I can clearly remember being in the car on a humid day with a little overcast. We were driving in the car when all of a sudden the wind started to pick up and it started raining a bit. Within five minutes, the weather progressed and there was so much wind blowing around the car that we could no longe .....

.... a sports prosthesis that would stand up to every day flexing of the knee for performance in sports. In order to develop this prosthesis they had to go through two main phases, the analysis of a jogger wearing a standard walking prosthesis and computer simulation of the flexing of the knee on this walking prosthesis. They had to measure rotation, weight bearing, moments, and the stress of the joints acting on this limb. After the mechanical actions were mapped out they had to use many mathematical equations to spring force and spring stiffness. All of this w .....

.... to be a particle and particles do not have any mass. Ideal gases obtain no volume unlike real gases which obtain small volumes. Also, since ideal gas particles excerpt no attractive forces, their collisions are elastic. Real gases excerpt small attractive forces. The pressure of an ideal gas is much greater than that of a real gas since its particles lack the attractive forces which hold the particles back when they collide. Therefore, they collide with less force. The differences between ideal gases and real gases can be viewed most clearly when the pressure is high, the temperature is low, the ga .....

.... oregano for perfumes, washing waters, and used it for dyes to turn wool purple and linen reddish brown. In good health and quality, oregano should have good color, even sized leaf pieces and a fresh aromatic aroma. The leaves of oregano are very aromatic, slightly pointed and hairy. The flowers are white, and bloom from late July to September. Oregano grows to be 2 feet tall, and rich, moist soil makes the aroma and flavor of oregano weak. Oregano has been used for many other things in the past, and has been very helpful and constructive to humans. It has been .....
