... 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 needs. During war times engineers, scientists, and inventors are brought together and their only duty is to invent military weapons. The weapons that the scientists come up with have to be m ...
... vomiting, diarrhea, skin rash, weakness, or inability to think clearly. The symptoms take about two weeks to go away if they don\'t lead to death. This bacterial pathogen is considered extremely dangerous and is probobly armed. Salmonella Typhi has been on the loose for many years and was cuased a lot of havoc and done a lot of damage over the years. Typhoid fever affects 17 million people worldwide every year, with approximately 600,000 deaths. To protect yourself from typhoid fever, aviod risky food and drinks and get vaccinated aginst typhoid fever, and wash your hands carefully a lot to make sure you have not touched something infected with Salmonella Ty ...
... and to not get sick or dizzy. Neon is an element that is lighter than air. The element is found most common in the atmosphere of the earth. It is also found in the earth¹ s crust. It was discovered in 1898 by Sir Walter Ramsey and Morris W. Travers. Its uses include electric signs,lamps,and lasers. Argon is the most abundant and most used noble on earth. It was discovered by Lord Rayleigh and by Sir Walter Ramsey in 1894. Argon makes up about 1.2 % of the earths atmosphere. It is found naturally in rock and in the air. It is used for electric light bulbs and floursent tubes. It is also used a lot in industry. Krypton a very rare noble was discovered by ...
... the absence of oxygen, pyruvic acid can be routed by the organism into one of three pathways: lactic acid fermentation, alcohol fermentation, or cellular (anaerobic) respiration. Humans cannot ferment alcohol in their own bodies, we lack the genetic information to do so. These biochemical pathways, with their myriad reactions catalyzed by reaction-specific enzymes all under genetic control, are extremely complex. We will only skim the surface at this time and in this course. Alcohol fermentation is the formation of alcohol from sugar. Yeast, when under anaerobic conditions, convert glucose to pyruvic acid via the glycolysis pathways, then go one step farther, co ...
... swordsmith Kinimune Okayoshi. Forging it by folding it over and over did not work out very well. So the forging could only be carried out when the metal had gotten so hot it turned white. Although somewhat irrelevant to the short story about the Shooting Star Swords, meterites do play an important part in science to day, and help scientist decode the birth of earth, our sun, and even the galaxy in which we are in. Today whenever a meteorite is found it is closely strdied by teams of scientist, to see if it could decode some of the many questions we have about our galaxy, and even the many galaxies found around ours. A single meteorite that has traveled millions ...
... power plant of the two types is the hydroelectric power plant. The main reason most countries use thermal versus the hydroelectric is because their countries don’t have enough concentrated water to create enough energy to generate electricity. (World Book vol. 14, 586) Nuclear power plants generate only about eleven percent of the world’s electricity. There are around 316 nuclear power plants in the world that create 213,000 megawatts of electricity. (INFOPEDIA) Radioactive, or nuclear, waste is the by-product of nuclear fission. Fission occurs when atoms’ nucleus’ split and cause a nuclear reaction. (General Information) Wh ...
... a separate order. It can thus be found with the other well-known intracellular parasites, rickettsiae, in diagnostic manuals. Until recently, however, there were no reliable and easy tests for chlamydia. Chlamydia prevention and patient care were impeded by the lack of suitable laboratory tests for screening and diagnosis. Such tests are now available. Through education, screening, partner referral, and proper patient care public health workers and health-care practitioners can combine efforts to decrease the morbidity and costs resulting from this infection. Chlamydia is the number one bacterial sexually transmitted disease (STD) in the United States today. ...
... galaxy over the next 100 million years. Researchers believe that while the gas is being swallowed by the black hole, the process will produce some amazing fireworks. The second puzzling question that astronomers are trying to answer is why isn't the black hole at the center of the galaxy? According to images from the Hubble Space Telescope, the black hole is 20 light-years from the center of the galaxy, but since the black hole is so massive it is hard to explain how it could have been moved. One idea is that the black hole is moving itself. Some astronomers think that the disk of dust serves as a "fuel tank." The black hole sucks in the material which is ...
... in Waterville Lake. The State and the mill implemented a dioxin minimization program in the mid-1980s and completed a modernization program in 1993 that will reduce water usage and discharges. About 94% of the estuaries and sounds in North Carolina fgully support designated uses. Agriculture, urban runoff, septic tanks, and point source discharges are the leading sources of nutrients, bacteria, and low dissolved oxygen that degrade estuaries. About half of the people in North Carolina use ground water as their primary supply of drinking water. Ground water quality is generally good. The leading source of ground water contamination is leaking underground sto ...
... in the next generation due to sampling error. Genetic drift usually occurs in small populations that contain less than 100 individuals, but in large populations drift may have no significant effect on the population. Another mechanism is gene flow which is when a population may gain or lose alleles by the migration of fertile individuals between populations. This may cause the allele frequencies in a gene pool to change and allow the organism to evolve. The most obvious mechanism would have to be mutation that arises in the gene pool of a population or individual. It is also the original source of the genetic variation that serves as raw material for natural ...
