.... monoxide, the ozone molecule is destroyed. So chlorine monoxide is an ozone destroyer. There is always a certain amount of chlorine monoxide in the atmosphere. It is important to remember that ozone is constantly being created and destroyed in the atmosphere. The amount of ozone in the atmosphere is based on these reactions. There are many factors that influence the amount of reactions like season, latitude, and solar cycle. Because of these factors ozone can vary wildly each day. In the northern latitudes there can be up to 40% difference than the day before. And in the equator regions, .....

.... that are often too small to be seen without the aid of a microscope. Microbes, also known as microorganisms, can be broken down into four classifications that are bacteria, viruses, fungi, and protozoa. Prescott, Harley & Klein (1990) describe bacteria as prokaryotic cells (cells that lack a true membrane enclosed nucleus). Bacteria are both small and simple in structure; they usually are between o.5 and 5cmm yet they have many characteristic shapes and sizes. Some bacteria are circular or oval shaped, they are known as cocci bacteria. Other bacteria are rod-shaped, they are .....

.... parry grass helps the in several ways it is one of the best objects to hide in for attack on other pray. It is also a good bedding source. The s cubs love to romp around in the grass for play and for practice for battle when they get older. This is the best all-round plant and helpful one for the . The up close, the is one of the smaller "big" cats. The largest weighs no more than 143 pounds and is probably 3.3 feet long from the shoulder to the root of its long tail. Females are usually slightly smaller than males. The outstanding feature of the 's appearance is, of course, its beauti .....

.... true, but it is not. There is one point being overlooked from all of this. The older, larger trees can store much, much more carbon dioxide than a new tree could. By cutting and burning these magnificent seasoned trees, the CO2 is being released back into the atmosphere. These releases of carbon dioxide add up in our surroundings, only to intensify Global Warming. Although this shows what happens when one burns and cuts down old forests, one must still plant new trees for long term plans, not letting them grow for a few years, to then cut them down. There are many methods for pla .....

.... does not evolve or change in time. There was no beginning in the past, nor will there be change in the future. This model assumes the perfect cosmological principle. This principle says that the universe is the same everywhere on the large scale, at all times.2 It maintains the same average density of matter forever. There are observational evidences found that can prove the Big Bang model is more reasonable than the Steady State model. First, the redshifts of distant galaxies. Redshift is a Doppler effect which states that if a galaxy is moving away, the spectral line of that .....

.... Microbes and bacteria probably sprouted everywhere in the warm and wet climate. Although now we only see a cold red planet, which was probably due to a collision of an astroid that would have set back the evolution process of Mars, causing it to be a harsh planet. A Viking spacecraft which landed on Mars in 1976 found that the planet was bathed in ultraviolet radiation, "intense enough so it would probably fry any microbe we know on this planet,"says Jack Farmer, an Ames researcher who calls himself an "exopaleontologist"—a searcher for fossils on other worlds. The redness of Mars .....

.... ¼ of a cent to make, while paper cost close to 3 cents. This is money we save as well as the store owner. This is a lot of money that is going to waste considering that plastic bags are so much more practical then paper. You can use them for lots of other things. You can take on trips to the grocery store, your can protect dry clothing from wet towels in an exercise bag. You can line your house hold waste basket with them, you tote dry shoes to work on rainy days. Hold plastic, aluminum and glass for recycling. Plastic bags are also very practical to carry. You can carry 5 compared .....

.... deep sea thermal vents, as well as bacteria that lives beneath the Earth's icy polar tundra's in the arctic and Antarctic. George W. Wetherill even notes that “Even if a planet or moon could not support life globally, each could contain a tiny niche where life could thrive” (Science News, 328). What are the most favorable conditions for life to develop? It is now known that life simply cannot emerge anywhere that does not contain water. It is mostly preferred that this water exists in liquid form, but there are possibilities that life can form in freezing as well as boiling conditions. .....

.... planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rivers/lakes like the river Tovdal in Norway had not yet begun to die. However by 1926 local inspectors were noticing that many of the lakes were beginning to show signs of death. Fish were found dead along the banks of many rive .....

.... animal in existence. I also found that it’s habitat is in the grassy plains of Africa. This is definitely a great place for it to hide based on it’s coat color. It is because of this combination of tall grass and camouflage coat which allows the cheetah to stalk and catch it’s prey. These usually consist of gazelles, wild boar, or pretty much any animal it can handle. However, the regular range for it’s food is about 88 pounds. The cheetah then drags the meat to it’s “home”, away from prying animals, and feasts on it immediately. The cheetah is a very interesting, so .....
