.... "Red tides are only occasionally red, also appearing as orange, brown, and even green. And they never occur literally as tides, which are the rises and falls of the sea." (New York Times: Aug. 27,1997) Some cases of red tides do not show any change in the color of the water at all. This makes a red tide very hard to predict or find. Red tides often occur when fresh water runoff creates a stratified surface layer above colder nutrient-rich waters. "heavy rains might have helped the red tides develop by pouring fresh water and nutrients into surrounding sea waters," (New York Times: Sept. 19, 1996) Fast growing algae quickly strip away nutrients in the upper layer, leaving ....

.... The Food Quality Protection Act have modified and enforced pesticide regulations. Consumer concerns with the usage of in the agricultural industry, in regards to health factors, have overwhelmed the U.S. Environmental Protection Agency (EPA) and demand they enforce pesticide regulations. With the assistance from other organizations such as the Senate Agriculture Committee (SAC), National Academy of Science (NAS), National Resources Defense Council (NRDC), and Consumers Union (CU), the EPA has made a notable progress. Throughout the years, consumers have pushed for research of the chemicals and substances that produce agricultural and what these do to our internal syst ....

.... hydroxide (milk of magnesia) and magnesium sulfate (Epson salt) are well known. Milk of magnesia is used in medicine as a laxative. Magnesium is also used in artificial limbs, vacuum cleaners, snow skis, wheelbarrows, and lawn mowers. In 975AD calcium was useful for setting broken bones. There have been many uses for calcium over the years, but calcium has not been available on a large scale until the twentieth century. Calcium is a metallic element, which is fifth in abundance in the Earth’s crust. It is essential for forming leaves, bones, shells, and Portland Cement. Calcium occurs in many highly useful compounds such as marble, limestone, and chalk. Plants a ....

.... the other chromosomes, or whether we should utilize the eight we have," he says. Dr. Willard is currently negotiating with an American company to develop prenatal diagnostic tests, which, because the current tests are time consuming and technically difficult to do, are restricted to women over 35 and those who have a family history of chromosomal abnormalities. Prenatal tests using Willard's probes would be much simpler and faster to perform and could be available to all pregnant women who wish to take advantage of the technology. Current prenatal testing involves growing fetal cells in vitro and examining them, over one or two months, to see if there are two copi ....

.... equation. Procedure: 1. Weigh out about 4.0g of KClO4 in a test tube. Record the accurate weight below. Product Weight Before Weight After Mass of Test tube + KClO4 41.5g 39.8g Mass of Test tube 37.5g 37.5 Mass of KClO4 4.0g 2.3g 2. Set up the apparatus shown below. 3. Gently heat the test tube containing the potassium perchlorate. Gas should begin to collect in the collection bottle. Record all observation. 4. Once the reaction is complete, no more gas give off, allow the test tube to cool. While the test tube is cooling test the gas in the collection bottle with glowing splint. Caution: Do not leave the rubber tubing down in the water trough during cooling o ....

.... the world. It strips forest soils of 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 b ....

.... been an logical answer that explained so much. Among this generation, the idea of God as the creator, or even a God period, has almost desisted. In this essay, I hope to present to you why science should not exempt this supernatural phenomenon from their studies. The "Big Bang Theory" states that fifteen billion years ago, give or take five billion years, the entirety of our universe was compressed into the confines of an atomic nucleus. Known as a singularity, this is the moment before creation when space and time did not exist. According to the prevailing cosmological models that explain our universe, an ineffable explosion, trillions of degrees in temperature on an ....

.... performed the first successful gene therapy on a human in 1990. They developed a protocol for treating Adenosine deaminase (ADA) deficiency, a severe combined immune deficiency, also known as the "Boy in the Bubble disease." ADA deficiency is a result of inheriting two copies of the defective ADA gene. Possession of a normal gene leads to the continuous, regular production of ADA in cells throughout the body. Without at least one properly functioning gene, children have no way of converting deoxyadenosine (a waste product) into inosine. This leads to the rapid build-up of deoxyadenosine in the system, which becomes phosphorlyzed into a toxic triphosphate, which kills T-cell ....
