Create a hypothesis for your study. Hypothesis: Residents of Hilo live longer‚ and are emotionally and physically healthier than residents from Kona because of the air

fluid called the mobile phase‚ which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds‚ causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound’s partition coefficient result in differential retention on the stationary phase and thus affect the separation. Thin layer chromatography (TLC) is a chromatographic

Friends are people whom we turn to when our spirits need a lift. They are always by our side through thick and thin. They stand beside us even when our disposition is not perfectly right and will fight for us if we are oppressed. Therefore‚ it is clear that friends play a vital role in shaping who we are today.

I believe that everyone has the ability to find patterns in situations and behaviors‚ however‚ not everyone is capable of making

the 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
