.... While slab are the destructive and deadly mountain slides. It is not uncommon for one of these to destroy a small town or forest. Since loose snow aren’t very dangerous, I will discuss slab . The fundamentals of how these snow masses occur, what to look for when testing and just all-together prevention. The basic chemistry behind a slab avalanche is when one layer of snow does not bond to the layer below it. Any kind of temperature change, fresh snowfall, the weight of a person, all can cause the slab to break free from the lower layer. The formation of a slab is possible in many ways. One way is for the snow to develop a crust and then there be more snowfall. Since sno ....

.... the has undergone a dramatic population resurgence because of human protection. Restrictions are still in place on capturing alligators from the wild (Beck). Studies have shown that using hormones such as norethindrone can be used to feminize alligator embryos at the male producing temperature (Lance, 79). This could lead to a way to help alligators increase in numbers of both sexes as well as help other members of the family Crocodylidae. Alligators are important ecologically and are dependent on the spatial and temporal patterns of water fluctuations. Patterns of courtship, mating, nesting, and habitat use are all dependent on marsh water levels. Alligators are a gr ....

.... kill off everything else. What did I pick to write on Acid rain with all the other important environmental topics? I chose it because we are subjected to precipitation all the time. I was interested to see just how dangerous acid rain is. If it really is dangerous, I was also interested to see what thing's people can do to help stop its effects. If we cannot stop the effects, I would atleast like to know something’s I can do to lessen the effects on our environment. What is acid rain? Acid rain is the name commonly given to the deposition of a cocktail of acidifying compounds to soils, surface waters and buildings. These compounds arise mainly from the combustion ....

.... to migrate into soil that is adjacent to the pavement. Over time, the accumulation akali metal salts can change the chemical profile of the soil which can lead to detrimental biological effects. Flame atomic spectroscopy provides a technique that can quantify metal concentrations in the extracts of the soil samples and consequently examine the relationship between distance from the point of road salt application and akali metal concentrations. Experimental Soil preparation: Six surface soil samples were collected at the intersection of Cold Spring Lane and the exit ramp of Interstate 83, in northwest Baltimore city. These samples were collected at distances from the roadw ....

.... get up to 482o C or 900 F. The heat on the surface of Venus can’t escape from the planet because there are thick clouds and heavy atmosphere around Venus. Venus has a lot of craters on its surface. There are 935 craters on Venus that are named after famous women. The largest crater is named crater Mead. Almost all of Venus has volcano rock on the surface. There is over 100,000 volcano’s and they dot the surface. One flow out of a volcano is over 4,300 miles long. Venus was the first planet to be reached by a space probe. The space probe Mariner 2 flew close to Venus that sent information to Earth. The Mariner 2 was from the United States. A space probe from the Sov ....

.... During high intensity exercise, oxygen is depleted and the body can not get enough oxygen to the muscle in order for them to perform their optimal potential. This lack of ability to get oxygen to the muscle is called oxygen debt and results in lactic acid being formed. Lactic acid is a waste product of anaerobic cellular respiration within the muscle tissue, which can cause muscle sourness that, usually, is felt after a hard or long workout. Fatigue usually sets in with the onset of lactic acid production. Oxygen is carried to the muscle by two delivery systems. Three percent of oxygen is carried in plasma and ninety-seven percent is in hemoglobin, the principal prot ....

.... in those seven days as they lived exactly today (Campbell p 421). Aside from past resistance, Darwin also comes under scrutiny still today as missing fossils which are to have been the bridge between a two familiar species are not yet found (Hitching p 3). Whatever the reason of belief or disbelief in Darwin's theories, he astounded the scientific world as well as the public and was able to convince many in the presence of a misguided past belief. This fact alone makes him one of the most important people of science ever. Charles Darwin was born in Shrewsbury-Shropshire, England on Feb 12, 1809 (GEA & RBi p 42). He was the fifth child in a wealthy English family with a ....

.... increased corn output in the United States. This increased output represents a major achievement for applied genetics. In 1929 practically no hybrid corn was grown among the 100 million acres of corn in the United States. But by 1970 the vast majority of 67 million acres was planted with the hybrid variety, yielding twice as much corn. Plant breeders have a definite advantage over animal breeders, because they can often produce fertile varieties - indeed, new species - by crossbreeding between species. This is because hybrids are often polypoid. Polyploidy, as we know, can occur naturally in the wild. Some species of cotton that we grow are polypodies that prob ....
