.... 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 control the overall body fluid. Mineralocorticoids are critical to regulate concentrations of minerals in extracellular fluids. The major target of aldosterone is the distal tubule of the kidneys. There it stimulates the exchange of sodium and potassium. It reaches .....

.... women, is caused by . Ectopic pregnancy is the leading cause of death of pregnant teens in the inner city and poor neighborhoods. also causes conjunctitis. This is a swelling of the eyes which can lead to blindness. The bacteria also can lead to pneumonia. Although it is the most easily treated STI, most people in danger won’t get checked until complications show, and that is why the disease is spread so much. It takes about three weeks for most people to see symptoms. In that time, they have sexual contact with others and not know they are spreading it. This process goes on and .....

.... and the social habits of the workplace, marketplace, and home. Can we discern how electronic commerce adds value to conventional marketplace transactions, making the Internet a preferred venue for business? Will markets of the future be substantially more efficient, to the extent of being "friction-free?" Or will a new regime of dominant players arise to eliminate competitors and create "winner-take-all" marketplaces? As electronic commerce spreads internationally, an equally profound issue is the fate of national sovereignty. Economic globalization, particularly of capital markets, is alteri .....

.... means they travel into the atmosphere virtually unharmed by rain or decomposition (Goldfarb 282). The reason these are causing such a commotion is the damage they cause to living things on Earth. When the ozone depletes, it causes more ultraviolet (UV) rays to hit the Earth's surface than are healthy (Singer and Crandall npg). UV rays affect the DNA of every living cell, altering the protein make-up of that cell (Goldfarb 288). Most importantly it affects "microscopic photoplankton" which rest at the bottom of the food chain, placing us in extreme danger (Goldfarb 288). Henry Lee, lea .....

.... non-symmetrical area of baldness, it is not the cause of androgenic alopecia. The typical pattern begins of occur at the hairline, then over time forms an “M”. The crown also begins to become thinner, as does the existing hair. Eventually, the “m” meets the thinned crown and forms the most common bald shape, the horseshoe. Currently, there are no treatments for male pattern baldness, so the condition is permanent. But, no treatment should be required if the person is comfortable with their appearance. At this time there is one drug that the FDA has approved fo .....

.... is September. Hurricanes form over the ocean. Easterly waves, what hurricanes develop from, are long, narrow regions of low pressure which occur in ocean winds called trade winds. At first, these easterly waves can grow into something called, a tropical depression. A tropical depression occurs when winds are up to 31 mph. Then tropical depressions can be upgraded into a tropical storm if the winds reach speeds of 74 mph or less. Then finally a the storm can be bumped up into a hurricane if the winds reach 75 mph. The National Weather Service is constantly trying to provide us with data .....

.... and ozone depleting substances such as CFCs, also known as Chlorofluorocarbons, hydrofluorocarbons, and perfluorocarbons. These gases are generated a number of human activities such as fossil fuel combustion, waste disposal in landfills, the use of a refrigerator, numerous agricultural and industrial activities, and the cutting down of numerous forests. These human practices have already changed the chemical make up of the atmosphere. Between the pre-industrial times and today, we have seen the concentration of carbon dioxide rise 30% in some regions, in particular the northern hemis .....

.... There was extensive research done in the area of embryo stem cells. Scientists have used such mouse stem cells for nearly a decade to create genetically altered mice (Travis Par. 8). Kaye Tucker of World Socialist Web Site writes, “These basic cells are present in the earliest stages of developing embryos and are able to develop into virtually any type of cell and tissue in the body” (Par. 3). This is where genes can be altered and clones can be made. It has been a hard task locating and being able to work with these stem cells because they are only around for a short time (Tucke .....

.... on the bottoms. Polar bears are the only bears that have this feature. These pads help the bear retain heat and to grip the ice and provide better traction. Polar bears are fast movers. When on uneven ice the bear will “trot”, moving its legs on opposite sides in unison. It can trot at 12 to 18 miles per hour. When it is running, it can reach speeds of up to 35 miles per hour. The bear can travel around 50 miles on an average day. The polar bear is also an expert swimmer. The bear has a long neck with a small head which help it to be more streamlined when it is in the water. .....

.... roof like butter and reaches and altitude of sixty meters. You can hear ripping, rending, wrenching, screeching, scraping, tearing sounds of a vast machine breaking apart. L. Ray Silver, a leading author who covered the disaster at Chernobyl, said that within the core, steam reacts with zirconium to produce that first explosive in nature’s arsenal, hydrogen. Near-molten fuel fragments shatter nearly incandescent graphite, torching chunks of it, exploding the hydrogen. The explosion breaks every pipe in the building rocking it with such power that the building is split into sections ( .....
