Every time 1% of the ozone layer is depleted‚ 2% more UV-B is able to reach the surface of the planet. So in short‚ without the ozone layer everything on earth will burn. The ozone layer is just as important to us as oxygen‚ without it the harmful UV radiation would give us server burns and destroy our delicate ecosystems. Even though there is hard evidence that proves that ozone depletion is harmful for organisms on earth‚ there are a few groups who think that the ozone layer is a “myth” aka doesn’t

For instance‚ the Baltimore‚ Pennsylvania‚ and the Parker are all based off the Pratt. Pratt Truss How the forces are spread out Here are two diagrams showing how the forces are spread out when the Pratt Truss is under a load. The first shows the load being applied across the entire top of the bridge. The second shows a localized load in the center of the bridge. In both

unknown amino acid. Within experimental error‚ the results were consistent with the reference literature cited in this report. Experimental Thin Layer Chromatography The amino acid standards used in this experiment were Alanine‚ Glycine‚ Serine‚ and Histidine. These standards and the unknown were separated by performing a method of chromatography. Thin layer chromatography (TLC) was performed by using a mobile phase and a stationary phase. The mobile phase was a nonpolar solvent composed of ethanol

TLC is used because it is “sensitive‚ fast‚ simple and inexpensive analytical technique”2 (Mohrig 151). The unknown solid (unknown #3 in this case) used in the experiment was obtained and added to a 2.5ml of Ethanol/dichloromethane in a test tube. This was the solvent used in the experiment because Dichloromethane volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes. The solid was already in powder form therefore we did not have

through the three different layers of the afterlife by Virgil. Dante is essentially getting a second chance on his life after this journey that is embraced by Dante. These different layers are started off with the Inferno which is the world’s version of Hell. After that‚ it is onto Purgatorio which is the between layer of Hell and Heaven where the souls are on the right track but still have to experience pain and suffering while on their way to the greatness. Then the final layer which is Paradiso and
