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

Extended Experimental Investigation | May 28 2013 | Drosophila melanogaster lab experiment Question: How do the dominant or recessive genes in particular traits in a cross between a male and female Drosophila determine the traits of its offspring? Aim: to establish whether characteristics produced from the offspring of a drosophila cross are recessive or dominant traits. Hypothesis: If certain phenotypes are expressed in the offspring from the cross of certain Drosophila‚ then the determination

Experiment #4 (10/31/14) Lab Review Objective To introduce the basic molecules of life and to test for their presence in different substances. Introduction Macromolecules are in all forms of life. These organic compounds are carbohydrates‚ lipids‚ proteins‚ and nucleic acids. These are monomers and they link together into long chains that form polymers. Different reagents can be used to find the presence of these macromolecules. Proteins are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and sometimes

Edward Dickson CHE101 DS-01 Experiment Date 7/21/2013 Report Submitted 7/21/2013 Title: Experiment #8: Ionic Reactions Purpose: In this lab we will work with aqueous solutions of ionic substances and determine if they are soluble. If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are

Perhaps the most significant text from the Galileo Dialogue seems to appear at the beginning when Salviati reveals that “in the Copernican position‚ the senses much deceive us when they visually show us‚ at close range and in a perfectly clear medium‚ the straight perpendicular descent of very heavy bodies. Despite all‚ according to Copernicus‚ vision deceives us in even so plain a matter and the motion is not straight at all‚ but mixed straight-and-circular”. This passage exposes the two most essential

Galileo Galilei Galileo Galilei‚ born Febuary 15th 1564 and died January 8th 1642‚ was a major contrubitor to science during the Scientific Revolution. As a physicist‚ mathematician‚ astronomer‚ and philosopher‚ his contributions include improvements to the telescope and consequent astronomical observations and support for heliocentrism. He also conducted experiments with pendulums‚ establishing the relationships between length and period. He also applied these principles to gravity‚ determining

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‚

"A Biography on the Life of Galileo Galilei" Galileo Galilei was an Italian astronomer‚ physicist‚ engineer‚ philosopher‚ teacher‚ and mathematician.(source 4) He made many improvements in his professions that he adapted. Galileo has been recognized and respected for his knowledge‚ and achievements in the physical‚ and natural world through his observations‚ and experiments. Galilei also exceeded in philosophy throughout his scientific and religious theories that have been explained in his books

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
