Submit your completed lab report to the Lab: Photosynthesis Lab assignment link for grading. For information on how this assignment will be graded‚ please visit the Course Information sectionChlorophyll and Accessory Pigments A pigment is any substance that absorbs light. The color we see comes from the wavelengths of light that reflect. Chlorophyll‚ the green pigment common to all photosynthetic cells‚ absorbs all wavelengths of visible light except green. The green reflects back to our eyes

Enzyme lab report. Introduction. An enzyme is a protein molecule that speeds up the rates of chemical reactions by many folds. They recognize‚ bind‚ and change specific reactants. They do not change thus can catalyze the same reaction again and again. Activation energy also known as an energy barrier is the amount of energy needed in order to begin a chemical reaction. Catecholase catalyzes the reaction rate of catechol oxidation. Catechol is found beneath the skin of many plants such

Introduction: The purpose of this lab is to apply Mendel’s laws to predict the probability of the occurrence of a single event‚ of two independent events and of certain traits in offspring of parents exhibiting traits. Gregor Mendel was an Austrian monk in 1866‚ who studied how traits were passed using pea plants. From his studies of inheritance‚ he created three laws of inheritance: the law of dominance‚ the law of segregation‚ and the law of independent assortment. He called genes ‘’factors’’

Radial Immunodiffussion (RID) Christian Crespo 18 October 2013 Immunology Lab Report Purpose of the Experiment: The objective of this experiment is to quantitatively observe the foundational reaction in our Immune system; the Antigen-Antibody interactions. The Ouchterlony procedure is what will be used in this lab to detect nature of the antibody interaction. The orientations of the band will provide more information about the interaction of antibody and antigen

Morgan Kimmerle Monday Lab Dr. McCorkell Abstract The purpose of this study was to cross and analyze the reciprocal crosses of wild flies and mutant flies. In this lab Drosophila melanogaster commonly known as fruit flies were used to understand some important genetic principles that were once proposed by Gregor Mendel. Mutant traits can be autosomal dominant‚ autosomal recessive traits‚ or even sex-linked dominant and sex-linked recessive. F1 and F2 generations were obtained by performing

Chromatography lab Purpose: To separate food colorings into their component dyes using paper chromatography. Materials: Chromatography paper‚ Food coloring‚ Ruler‚ Pencil‚ Solvent solution‚ Test tubes‚ Test tube rack. Safety precaution: wear aprons‚ to make sure that you don’t get any of the alcohol on your clothes‚ and if you break a test tube you don’t get glass on you. Procedure: See-attached handout. Results: See chromatography with Audrey’s lab report.

Alka-Seltzer Rocket Formal Lab Report Abstract In the Alka-Seltzer Rocket lab one was to experimentally determine how much (grams) Alka-Seltzer and water in mL‚ is needed to launch the rocket the highest/longest distance in cm. Also to experimentally determine the % NaHCO3 in the tablet using the information from the highest/longest distance. Calculate the error and % error of NaHCO3 in an Alka-Seltzer tablet and to determine the limiting reagent for the highest/longest distance traveled. Alka-Seltzer

Lalin Candium Lab Report Chemistry Block H Mr. Neil Chipman Calculating the Atomic Mass for Different Candium Isotopes Objective: In this experiment I will be discovering the atomic weight of Candium isotopes. By doing this experiment‚ it helps us to know how to calculate the relative abundance and atomic mass of each Candium isotopes without having to use the spectrometer. This lab will achieve my understanding of isotopes and why it has different masses but same number of protons due

Title: The Effect of Nicotine on the Heart Rate of the Lumbriculus Variegatus Introduction: Background- This lab is being done to demonstrate the effects of stimulants on the circulatory system of blackworms. In this lab‚ the stimulant we have chosen to use is Nicotine. A stimulant is an agent that causes increased activity‚ especially in the nervous or cardiovascular systems. In this lab‚ we will put blackworms into the Nicotine to look at the differences in pulse rates when compared to a control

Mallory Charland February 9‚ 2015 Mutations of E. coli Lab Report Advanced Biology Deducing Mutations of the Lac Operon of E. coli Abstract: In this lab we determined a possible mutation in unique bacterial strains of E. coli by observing the proper responses of wild type E. coli Lac Operon as a control group. Mutated strains of E. coli were placed in four test tubes‚ each containing a different substance (lactose‚ glucose‚ water and lactose and glucose)
