.... When the atom is split, it releases two more neutrons. These neutrons can then strike two more uranium atoms. The split of each atom will produce two more neutrons. The more atoms that are split the more neutrons produced that will split more atoms. As this process is repeated over, it becomes a self-sustaining chain reaction. This energy producing process is called a chain reaction. uses the uranium-235 element because it is the easiest of all atoms to split apart. Uranium-235 is made up of many protons and few neutrons. Protons naturally repel one another so a nucleus made up of many protons tends to ‘fly apart’ more easily. In addition, uranium makes a good nucl ....

.... of tissues throughout the body. The release of adrenaline prevents hypoglycemia (low blood sugar), by binding adrenergic receptors in the hormone releasing cells of the pancreas. Epinephrine is called the “fight” or “flight” hormone. The actions of epinephrine and norepinephrine are generally similar, although they differ from each other in their effects. Norepinephrine constricts almost all blood vessels. Norepinephrine is formed by intravenous infusion to combat the fall in blood pressure associated with types of shock. Norepinephrine is formed in the body from the amino acid tyrosine, and epinephrine is formed from norepinephrine. Mineralocorticoids steroids c ....

.... In-home communication inventions have greatly affected the ways of modern living, and I intend to prove that in this report. People invent for many reasons. Some hope to make money, others invent to make life more convenient, and some even invent to satisfy their curiosity of their urge to create (7,364/5), but satisfying economic needs, was one of the main reasons for invention. The economic inventions needed were devices, machines, business, and industry-processes and products. The majority of economic inventions collaborate with one another; a lot of things were invented to make other inventions work. Another major reason people invent is to satisfy military ne ....

.... There are three main types of muscles. The first is skeletal. Skeletal muscle makes up the largest mass of muscle in the body, and is the type of muscle that is attached to bones and moves the skeleton in a conscious control, so therefore it is a voluntary muscle. Its contractions are short and strong, providing the force needed for movement. The muscle contractions produce and provide some heat needed in the body. Skeletal muscle tissue is made up of smaller fibers called myofibrils. These myofibrils are composed of even smaller protein filaments. These filaments can be either thick or thin. The thick filaments are made of the protein myosin, and the thin filament ....

.... It was Jan Ingenhouz with Jean Senebier in Geneva that founded the basic gist of the theory of photosynthesis in plants. My experiment involves testing different brands of plant food on plants to see what brand of plant food makes the plant grow the tallest. I will test three types of plant food on three sets of plants and one set with no food. I will water the plants all the same amount and let all the plants get the same amount of sun, then measure the height of all the plants at the end of six weeks and record the data. The first step of photosynthesis is the absorption of light by a chlorophyll molecule. "The energy of the absorbed photon is transferred from one chlo ....

.... their intellect only contributed partially to their success. Intellect and planning, combined with chance and luck contributed to their overall success. People take chances on a daily basis. If you actually stop and think about it, life is one big game of chance. It is by chance that we are born, that we continue to survive, and that we will eventually die. Some people feel that this cycle occurs do to the will of God, others, like Charles Darwin believe that it happens based on chance or natural selection. Whatever you believe or disbelieve, life cannot be planned. No matter how hard a person attempts to "plan" their path in life, it is by chance and luck where tha ....

.... all documented cases, however, involve persons between the ages of 15 and 30. Both men and women are affected, but studies suggest that the disease occurs slightly more often in men than in women. Doctors estimate that each year 50 out of every 100,000 Americans have symptoms. Among college students, the rate is several times higher. does not occur in any particular "season," although authorities in colleges and schools, where the disease has been well studied, report that they see most patients in the fall and early spring. Epidemics do not occur, but doctors have reported clustering of cases. Transmission: EBV, the virus that causes most cases of , infects and reproduce ....

.... of these mysterious floating objects. In actuality they haven't gotten us much further on the mission for proof of other living beings in the universe. But in a universe so incomprehensibly large that we no not even a boundary, I sincerely doubt that the human race is the only form of life. It seems certain scientists have come up with other hypotheses concerning UFO's. While all astronomers yearn for a concrete explanation on UFO's, their beliefs on their origin contrast. Many looking for a more scientific definition disregard UFO's as nothing more than a mere misinterpretation of a plane, weather balloon, or meteor. Some have gone so far as to say that spec ....
