.... natural gas. Sugar, starch, and paper are compounds of carbon with hydrogen and oxygen. Proteins such as hair, meat, and silk contain these and other elements such as nitrogen, phosphorus, and sulfur. More than six and a half million compounds of the element carbon, many times more then those of any other element, are known, and more are discovered and synthesized each week. Hundreds of carbon compounds are commercially important but the element itself in the forms of diamond, graphite, charcoal, and carbon black is also used in a variety of manufactured products. Besides the wide occurrence of car .....

To have an opinion on whether steroids are safe are not, it would help to know how they work and what responsibilities are needed when choosing to take them. are a synthetic for of the naturally occurring hormone, testosterone. are used to promote accelerated muscle hypertrophy in both males and females. Hypertrophy describes the increase in size of muscle as the result of stress put upon the muscle. Muscles go through hypertrophy in order to adapt to the increased .....

.... funding would be necessary to construct a space station? At first, NASA could only work within the agency’s estimated $8.5 billion dollar budget. It was in 1984 when the first construction plan was unveiled, called “Freedom.” A “power tower” concept was designed, which is a long slender unit that would be the center of the entire structure. This tower would be a long, narrow piece of latticework, chosen for its stability and to avoid the use of every day thrusts to maintain its altitude. All the laboratory modules would then .....

.... and remains chemically unchanged by the end of the experiment. A catalyst lowers the activation energy. This is the energy needed to start a reaction. The variable that I have decided to change is the temperature. I have decided to alter the temperature of the yeast and time the amount of carbon dioxide that will be given off at different temperatures. I have decided to time how much carbon dioxide is given off in five minutes. Throughout the investigation, I will keep the temperature the same as I have specified for each reading. For example, if I a .....

.... the wastewater flow. Industrial Applications: The application of this reaction to the industrial world consists of a set of processes to filter out the phosphate. The setup is the following: Purpose: Restrict phosphates to aluminum phosphates for easier disposal of phosphorus. The first step in phosphorus removal is the Rapid Mix. In this stage, alum and waste or water runoff(known as effluent) is blended together as rapidly as possible with the use of a high-speed mixer called a "flash mixer." After this instant mixing, a slower moving process calle .....

.... walking time bombs. Some people will say it is progress, but the majority drives it for the convenience. Why walk four miles in four hours when you can drive the same miles in four minutes? Another popular source of waste is the post-consumer market. American citizens throw away millions of tons of garbage each year, and this trash has to go somewhere. While there are projects underway to clean and reuse this refuse most of it gets dumped into huge landfills. These landfills are disgusting festering blisters on our country's landscape. But people continue to co .....

.... microscopic organisms appeal to you, you should look into microbiology, phycology, or mycology. If you are artistic, ornamental horticulture and landscape design might be right up your alley. If you worry about feeding the hungry, you should study plant pathology or plant breeding. At some larger universities, you can even study specific types of , each with its own department. These departments include argonomy (field crops), microbiology (microbes like bacteria and fungi), horticulture (fruits, ornamentals, and veggies), and plant pathology (diseases pertai .....

.... are made to be ready for to take place. The chromatis is coiled up and consists of loose threads. In prophase, the next longest stage, the chromatin becomes chromatids which later form chromosomes. They are attached to the centrioles by spindle fibers. The chromosomes are lined up in the center of the celll. The nucleolus and nuclear membrane disappear. In the next phase, metaphase, the chromosomes line up along the metaphase plate. The plate is the midpoint of the cell between the two centrioles which are located at opposite poles. During anaphase, the centrioles start playing tug of war with the ch .....
