function Abstract In this lab the structures of various cells were viewed through a compound microscope. The bacteria in yogurt was viewed a long with a slice of potato‚ and a thin skin of red onion. The potato was dyed with iodine while the red onion was dyed with methane blue. The students had to assemble the first three slides. Two more slides were provided these are the yeast and protozoa cells. Those two are also viewed with the same microscope. Introduction

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

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
