Lab 5.3 SPRINGS- HOOKES LAW Group member: Submitted by: Submitted to: Class: Due: Lab 5.3 SPRINGS- HOOKES LAW Purpose: To study the characteristics of a spring. Hypothesis: With an increase in weight there will be a directly relatable increase in spring length. Additionally each spring will increase to different expected lengths. Materials: -Light spring -Dense spring -Brass spring -Masses -Ruler

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

products produced. The uncertainty of this this measurement is ± 1 product. In order for this experiment to be controlled‚ many variable were identified and held constant. If these variables were not to be held constant than the findings of this experiment would be meaningless because there would be no way of desiring if the independent variable was the cause of the changes which were recorded In this experiment‚

In this lab‚ there was a comparison between accuracy and precision of densities measured by volume. Mass measurements are often used units in the metric system. Volume can be examined a borrowed unit. The volume measurements were made in mL. Every measurement had a level of hesitancy affiliated with it. The experiment could feel uncertain from the object used for measurement and from the accuracy of the person doing the measuring of the volume. Because of this uncertainty‚ the experiment must be

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

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 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

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

The Effect of Temperature on Animal and Fungal Amylase’s Ability to Breakdown Starch. Abstract This experiment was designed to test the reaction of the enzyme amylase at various temperatures. There were two different kinds of amylase being tested‚ one was fungal amylase also known as aspergillus oryzae and human amylase. The changes in temperature effect the rate at which an enzyme and a substrate collide. When the temperature is too high the active site changes shape or denatures‚ once this
