... globally. The American economy depends on imports and exports. Foreign trade, both imports and exports accounts for a little over 25 percent of goods and services produced in the United States, and even more in countries like Japan and Germany. This percentage is currently and will continue to grow in the future (5). Globalization of the world’s industrial economies greatly enhances the value of information to the firm and offers new opportunities to businesses. Today, information systems provide the communication and analytic power that firms need to conduct trades and manage businesses on a global scale. Globalization and information technology also brings ...

... per minute while it is at rest, but it will be able to deliver a greater amount of blood with each stroke as a result of adequate conditioning. Conditioning has other benefits to cardiovascular fitness as well. It will increase oxygenation of the blood due to the fact that while exercising deep breathing increases the blood flow to the lungs. Under a well-planned conditioning program conditioning can help to decrease cholesterol and the incidents of deadly heart disease. Individuals who exercise regularly have a lower rate of heart attacks than individuals who do not participate in an exercise program. One of the most important aspects of conditioning for the hear ...

... of alcohol on the human body depend on the amount of alcohol in the blood (blood-alcohol concentration). This varies with the rate of consumption and with the rate at which the drinker's physical system absorbs and metabolizes alcohol. The higher the alcohol content of the beverage consumed, the more alcohol will enter the bloodstream. The amount and type of food in the stomach also affect the absorption rate. Drinking when the stomach is filled is less intoxicating than when it is empty; the foods in the stomach, which contain fat and protein, delay alcohol absorption. Body weight is also a factor; the heavier the person, the slower the absorption of alcohol. After ...

... in one night. It has been estimated they do $1 billion damage per year in North and South America today, these ants still cause millions of dollars in crop losses in many South American countries. Although primarily an agricultural pest, this insect on occasion may invade the home for cereals. In the United States, the Texas leaf-cutting ant, Atta texana , occurs in Texas and Louisiana. This ant is believed to cause a total yearly loss of $5 million in the United States (unison services. 1998). There are about 9,500 named species of ants. These ants are divided into 16 sub families and 300 genera, all which belong to the family called Formicidae, the family of ...

... material called the matrix, an area which contains RNA, DNA, proteins, ribosomes and range of solutes. This is similar to the contents of the chloroplast stroma and like the chloroplast, the mitochondrion is a semi-autonomous organelles containing the machinery for the production of some of its own proteins. The main function of the mitochondrion is the oxidation of the pyruvate derived from glycolysis and related processes to produce the ATP required to perform cellular work.(Campbell 182-9) Pyruvate, or fatty acids from the breakdown of triglycerides or phospholipids, pass easily through pores in the outer mitochondrial membrane made up of a channel protein ca ...

... a brown gas which is soluble in water. These are just a few of the chemical properties of nitric oxide. With the total life expectancy of nitric oxide being from six to ten seconds, it is not surprising that it has not been until recently that it was discovered in the body. The compound is 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 accounta ...

... and then stuffed with goose feathers. Upon drying, the feathers expanded and the leather contracted, forming an extremely hard mass. This was hammered round and painted white. The feathery sometimes flew over 300 yards and was durable - until it got wet. Then it would split open. The Gutta percha was introduced in 1850 and was made of a rubberlike sap from the Malaysian sapdilla tree. The material was heated to soften it and then hand-formed into a solid, one piece ball.Gutta percha was black, so the early balls were painted white. Easier to make, less expensive, and more durable, the gutta revolutionized golf. When golfers discovered that balls and ...

... of Mars is quite different from that of Earth. It is composed primarily of carbon dioxide with small amounts of other gases. The six most common components of the atmosphere are Carbon Dioxide at 95.32%; Nitrogen at 2.7%; Argon at 1.6%; Oxygen at 0.13%; Water at 0.03%; and Neon at 0.00025 %. Martian air contains only about 1/1,000 as much water as our air, but even this small amount can condense out, forming clouds that rise high in the atmosphere or swirl around the slopes of towering volcanoes. Local patches of early morning fog can form in valleys. At the Viking Lander 2 site, a thin layer of water frost covered the ground each winter. There is evidence that ...

... arises through random changes (called mutations) to existing genes. Genes are the chemicals that determine the traits and characteristics of animals and plants. Every trait has one or more gene associated with it. Thus, natural selection provides the animals and plants with the best genes. Supporters of neo-Darwinism believe that natural selection operating upon random variation gave rise rise to all animals and plants. While the source of variation is random, the direction of evolution is not. In effect, natural selection removes chance, and it makes the theory of evolution plausible. If neo-Darwinism is correct then numerous small successive c ...

... nutrients and damages farm crops. Acid rain can also corrode stone buildings, bridges, and priceless monuments. Acid rain can also be harmful to humans because acid rain kills the crops and fish we eat, ruins homes, and the acid can release lead in the pipes and the lead could go into our drinking water. It is hard to determine where acid rain may fall next, because the wind from a pollueted area could carry pollution to another area and the acid rain could fall there. The regions effected more by acid rain is large parts of eastern North America, Scandinavia, and central Europe. In alot of places acid rain isn't a probelm because some soils can neutralize the aci ...
