.... feather-like bands that are not attached to each other, and is usually white with no shading. Cirrocumulus clouds appear like very small round balls or flakes. The cirrocumulus clouds sometimes form a pattern of a buttermilk sky. The cirrostratus clouds sometimes form tangled webs or thin whitish sheets. A large ring or halo is sometimes seen around the sun or moon when the cirrostratus covers the sky. The middle layer of clouds range in altitude from 6,500 to 23,000 feet. The altocumulus, altostratus, and nimbostratus clouds are found in the middle d .....

.... Then thirty centimetres cubed of 2 molar HCL was measured using a measuring cylinder. The acid was then placed into the polystyrene cup and its temperature was taken and recorded using the thermometer. The pre-weighted sodium hydrogencarbonate was then added to the solution, and the final temperature was recorded. The contents of the cup were then emptied out and the cup was washed out with water and then thoroughly dried. This was done three times for the sodium hydrogen carbonate so that I could remove any anomalies that were obtained. The experiment wa .....

.... 5,550,000 plastic, metal, and glass containers into the ocean in a single day.2 The most harmful of these is plastic. Sea mammals such as birds and dolphins often get tangled in the plastic six-pack rings, fishing lines, and net that humans discard into the ocean waters. Once entangled, they are unable to free themselves which can cause deep cuts, starvation, and drowning. Many ocean mammals have died as a result of ingesting these plastic items. In 1985, a sperm whale beached itself on a New Jersey shore; a mylar balloon was lodged in its stomach, and three .....

.... unknown. The same deadly radiation that was present in this explosion is also present in spent fuels. This presents special problems in the handling, storage, and disposal of the depleted uranium. When nuclear fuel is first loaded into a reactor, 238U and 235U are present. When in the reactor, the 235U is gradually depleted and gives rise to fission products, generally, cesium (137Cs) and strontium (90Sr). These waste materials are very unstable and have to undergo radioactive disintegration before they can be transformed into stable isotopes. Each radi .....

.... to 90 million over the course of the 14 century. The plague moved along the caravan routes toward the West. By 1345 it had made it’s way to the lower Volga River. By early 1347 it was in Constantinople. It hit Alexandria in the autumn of that year, and by spring 1348, a thousand people a day were dying there. In Cairo, Egypt, the count was seven times that. The disease traveled by ship as readily as by land and it was no sooner in the eastern Mediterranean than it was in the western end as well. Already in 1347, the plague had hit Sicily. By winter t .....

.... in an alternate path through a new technique called "packet switching". Packet Switching is a means of breaking up the message being sent into small packets which carry enough information to seek out its destination and sending them out separately towards the destination server. The message after being broken up would take separate routes to the destination and then be re-assembled by the computer at the server where the message was being sent. This was good because with more than one route for information to travel on, the enemy did not have one central poin .....

.... to playing a game of Russian Roulette. One-forth of existing medicines comes from tropical plants whose homes are in the rainforests of South America. For every acre that is lost in the burning season, there is one acre less that we have for possible life saving medicines. About 70 percent of plants used in anti- cancer drug come are the rain forest. We are slowly destroying the environment and ourselves. Whether we realize it or not, the world could quickly come to an ecological stop. Every day 144,000 acres of the rainforests are cut down, slashed and/o .....

.... first bacterium shown to be the cause of a disease. is a very large, gram positive sporeforming rod. The organism is cultivated on ordinary nutrient medium and grows best aerobically, but can also multiply under anaerobic conditions. The disease, Anthrax, is very deadly but it is rare. The risk of infection is 1/100,000. The disease is acquired when spores from a contaminated animal carcass inoculate an open wound. Then, the spores germinate and invade the blood stream, leading to death within 48 hours. is classified as a harmful, pathogenic bacterium. There is a vaccine for Anthrax in humans, but it pro .....
