TITLE AND AUTHOR Lab 7 Analysis of purified Concanavalin A via:Hemagglutination INTRODUCTION The purpose of this lab was to test the biological activity of ConA by performing a hemagglutination assay. If ConA is active then agglutination will occur due to ConA’s free receptors being able to bind to the glucose residues on the sheep’s red blood cells. If ConA is not active then no agglutination will occur. To test the hemagglutination reaction‚ two types of ConA solutions

Title of Practical: The Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction

Hypothesis If we test the amount of electrolytes in an energy drink and orange juice‚ then orange juice will have more electrolytes than an energy drink. Variables Independent Variable- the two different drinks‚ orange juice and an energy drink Dependent Variable- the amount of electrolytes in each to determine whether or not one has more than another Controlled Variable- same multimeter‚ same brand and type of alligator clips leads‚ same gauge‚ length‚ and brand of copper wiring‚ same brand

A key component of the quantification of the protein concentration in the given samples was the generation of a standard curve. The data presented in Table 1 produced the graph in Figure 1 which was then used to calculate a line of best fit. The line of best fit yielded an equation y= 0.44976x which was in turn used to calculate unknown protein concentrations of given samples. The absorbances of the whole milk‚ cereal milk and muscle milk had been previously obtained and recorded via spectrophotometer

Electrochemical Cells Lab Report AP Chemistry Block 1 Analysis: The purpose of Part 1 of this laboratory is to construct a table listing the reduction potentials of a series of metal ions in order of ease of reduction. The series of half-cells is constructed by placing a piece of metal into a 1.0 M solution of its ions for each metal in the series. The metals are Cu‚ Fe‚ Pb‚ Mg‚ Ag‚ and Zn. The half-cells are connected by a salt bridge constructed of a strip of filter paper soaked in a solution

Effects of Molasses Concentration on Yeast Fermentation The purpose of this lab was to determine how yeast cells are affected by the concentration of a food source‚ and for our purposes‚ the food sources were corn syrup and molasses. Our hypothesis was that the yeast cells would ferment the most when there was a higher concentration of molasses/corn syrup. In order to test this‚ we created 10 test tubes with decreasing concentrations of molasses/corn syrup using a serial dilution. Each test

different sucrose concentrations then the tube with the lowest concentration of sucrose will expand the potato the most because the water will move into the potato to even out the concentration levels of the sucrose/ water ratio inside and outside of the potato was supported by the data. The data shows that the potato submerged in the lowest concentration of the sucrose water solution had the greatest percent change in mass at 15.2% for 0% concentration. Overall‚ the higher the concentration of the solution

Brayden Shaver Electrolytes in Sports Drinks September 30‚ 2016 Electrolytes in Sports Drinks Drinks are full of many substances that make up the taste‚ color‚ and uses of the beverages. One very important part of a sports drink are electrolytes. An electrolyte is a liquid gel that contains ions and can be decomposed by electrolysis‚ it is present in a battery. This substance is in many of the everyday drinks we use. From the orange juice we drink in the morning to the many sports drinks

Electrolyte Challenge Sport Drinks vs. Orange Juice By: Clem L. Vinegar Jr. Mr. Wells February 2‚ 2013 I. Project Question- The question I am trying to answer is which drink between water‚ Gatorade‚ propel‚ PowerAde‚ and a homemade drink. II. Hypothesis- My hypothesis is that orange juice will have more electrolytes than the other drinks because of the natural electrolytes it contains from oranges. I also think that Gatorade will be the most preferred
