No; the experiment was not successful‚ because it did not show the correct fluorescence gradation of the serial dilution of the DNA concentration. As shown by the picture‚ only the first drop of the DNA/EtBr mixture for the DNA standards fluoresce brightly under the UV light‚ while the other spots for both the DNA standards and the unknown DNA standards were all dimly fluoresce. This was due to pipetting error; the tip of the pipette did not touch the liquid (TE) in the micro-centrifuge‚ so no DNA

The concentration camps was a place where people were detained and confined. The concentration camps are where they held jewish people against their own will. The concentration camps was where the Germans placed the Jews to hostage before killing them. There are three specific concentration camps that the Jews were sent too. The three concentration camps were the transit camps‚ forced labour or work camps‚ and extermination camps. Adolf Hitler just wanted to prove his power to everyone. The

In this folio task‚ the impact of drug absorption and blood stream concentration‚ on the human body‚ will be observed. The rate of absorption and clearance of the drug‚ relies on many factors. The drugs blood stream concentration‚ time of administration‚ absorption rate‚ clearance rate and the effect of certain parameters‚ will be calculated. This can be completed through using a surge function‚ calculus (derivatives) and straight line graphs (). Graphing technology on the graphics calculator

5-dinitrobenzoic acid to oxidize the aldehyde group on the carbohydrate‚ the reducing end of glucose increases in absorbance of 540 nm. Using a UV spectrophotometer‚ the concentration was calculated by using a regression line of the standard curve. The experimental data concluded a 1068.912 µg/ml. With the actual concentration being 1200.000 µg/ml‚ a 10.924% error was deduced. Though the error is slightly high‚ the deviation of 134.370 µg/ml makes up for some of the error through this process;

Noel Arackal 1.25.16 Bisc 4930 Experiment No. 1 – Varying Extracellular Concentration Introduction: This experiment sets out to determine the tonicity of solutions with varying concentrations of sodium chloride on the red blood cells of sheep by measuring the transmittance of a red blood cell/NaCl solution with a spectrometer. This is done in order to study the effects of solutions containing varying levels of tonicity to red blood cells. Tonicity describes what happens to a cell when it is

investigation: The effect of solute concentration on osmosis in potatoes. Research question: What is the solute concentration of a potato? Hypothesis: Osmosis is the movement of water across the membrane from an area of high concentration to an area of low concentration. The osmosis continues until the solute concentrations are equal in both areas. In this experiment‚ we put pieces of potatoes into test tubes with sugar solutions of different concentrations and leave them there over night. It

The aim of this experiment is to better understand the process of fermentation of yeast in different concentrations of sucrose. The experiment worked with yeast and sugar (sucrose and glucose) to determine the rate of fermentation by testing the pressure of C02 in the test tube. The experiment tested the metabolic capability of yeast anaerobically meaning no oxygen was present (this was ensured by the thin layer of oil on the top of the solution). This means that the metabolic rate of the yeast could

they depicted true thoughts of Jewish captives during this time period. Though most of the novel described life in concentration camps‚ three lines truly portray the feelings‚ emotions and mindset Jews had under the Nazi regime. "Never shall I forget those moments that murdered my God and my soul and turned my dreams to ashes..." (Wiesel 34). This line shows the impact concentration camps had on Wiesel’s life‚ soul‚ and belief. As a child‚ Wiesel became Godless for he saw no God of his would allow

War World 2‚ Concentration Camps During War World 2‚ Hitler authorized the SS‚ after December 1934‚ to be “the only agency authorized to establish and manage factories‚” called concentration camps‚ like Ravensbruck (ushmm.org). These camps were built throughout Germany and the system expanded as the Nazis took over. The system of the camps grew more deadly and affected many camps‚ like Ravensbruck. Ravensbruck was a camp mainly for women‚ and was deadly. In the end of the war‚ Ravensbruck was
