The Elvis Experiment Introduction: In this experiment we will determine how the difference in length and diameter of a blood vessel have an effect on the resistance of blood flow and how the viscosity of blood will also effect the resistance of blood flow in a blood vessel. Observation: My mom is a big Elvis fan and she always wondered how his health affected his death. Knowing that he had high cholesterol and high blood pressure I decided to do an experiment on what factors may have had an effect

discrepancies during the experiment which could throw off the data but in all everything went correctly. Discussion for errors: There were some parts during the experiments that the group could not distinguish when the color change occurred so there was more solute going into the mix than there should have been. Also at one point there was the mistake in part B of using KHP and HCl together instead of the NaOH so that mistake skewed results just a little. Conclusion: For this experiment‚ it was essential

It would be nearly impossible to have the transportation of vesicles without kinesin to guide it. And without the transportation of these synaptic vesicles to release their neurotransmitters‚ there would be no movement in the cell at all. This experiment is so important because vesicle transport in neurons helps to identify many neurological disorders. One such example is a research on Drosophila. Since there is only one kinesin light gene in the subject‚ the mutants in that one chain gene exhibit

An Experiment of Adaptation Introduction: Throughout history of time‚ organisms change in relation to their environment‚ consequently‚ adaptation is an essential property of life. This experiment is designed to test the adaptation of Drosophila melanogaster. This kind of insect is also called fruit flies‚ it has been widely used in scientific research because it has a short life cycle about two weeks and it is easy to keep large numbers of them (Manning). Two groups of this species will be used

itself when injured. However‚ the human body is not the only living thing that has a way of healing with no help. Planaria‚ which are free-living flatworms‚ are known for their quick regeneration from a fraction of the body. Scientists have been studying planaria and the effects of magnetism on the regeneration rate of the planaria. The hypothesis of this experiment is that if the planarians are exposed to a certain number of magnets at a closer distance‚ then they will regenerate stronger and faster

Purpose: Can the penny hold more drops of water or more drops of the MYSTERY liquid? Research: Cohesion- The state of sticking together. Pennies can hold more water because soap reduces the cohesion of water and the water molecules break apart and can’t stay on the penny. Hypothesis: The penny will hold more a larger number of drops of water because water is more cohesive than the “mystery” liquids Variables: Independent variable: Penny Dependent variable: Number of Drops of Water Control

For the seventh experiment we will be performing different type of test to see how different chemical react with each other. The first experiment will be a demonstration the professor will give to the class. the first experiment you will be performing will include a test tube you will add a couple drops of dilute hydrochloric. you will add this to five little pieces of zinc metal. In next experiment you will performed you will put 2 ml of 3% hydrogen peroxide solution in a test tube .you will also

The purpose of Experiment 36 is to identify the anions present in an unknown solution based on the chemical reactions with various chlorides. In this experiment‚ Pb2+ was present in the unknown solution‚ while the presence Hg22+ is in doubt‚ and Ag+ is absent. To begin‚ the first part of the experiment involved analyzing the results from the experiment with the solution with equal volumes of AgNO3‚ Pb(NO3)2‚ and Hg2(NO3)2. Based on the results and observations obtained from the tests with the stock

water‚ it will affect the swimming speed of the paramecium. The various students groups have individual experiment of how dose NaCl affect swimming speed of Paramecium‚ but the experiment did not show the result clearly to students. Therefore‚ after they finish the presentation‚ most of the students want to find out the chemical NaCl increases swim speed of Paramecium. Experiment Design The experiment prediction is if we add 4mL of Paramecium to 25mL of 0.2M NaCl and 225mL of Dryl’s solution‚ then Paramecium

The purpose of my experiment is to determine which temperature will allow Luminol to glow at its greatest capacity. My hypothesis is that the glow will illuminate for the longest time in a cold temperature because it will take longer to dissolve. I also predict that in the warmer temperature‚ the glow will be at it’s brightest. Luminol is a chemical‚ which exhibits chemiluminescence with a blue glow. It is a solid that is soluble in most polar solvents‚ but insoluble in water. Luminol is widely
