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

1.0 Introduction 1.1 Aim and Assumptions: The aim of this experiment is to observe the rate of diffusion of diethyl ether vapour into stagnant air‚ and then determine the diffusivity. An error analysis of this calculation also had to be carried out. The following assumptions made were: * Diethyl Ether is an ideal gas * Partial pressure at the top of the tube was equal to zero * Mass transfer resistance between the liquid surface at the bottom of the tube is insufficient‚ compared with the

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

Statics and Uncertainty Marilyn Esthappan Lab Partner: Nisha Sunny TA: Sajjad Tahir Physics Lab 106 May 29‚ 2011 1-3pm THEORY: Statistical variation and measurement uncertainty are unavoidable. A theory is consistent if the measurement is 2m +/- 1m. Uncertainty rises from statistical variation‚ measurement precision‚ or systematic error. EXPERIMENTAL OVERVIEW: Part 1. Coin Toss: Statistical Variation: Sixteen coins were tossed nine times and the number of heads was counted to determine

Planarian Lab Report Hanna Klein Bishop Fenwick High School Planarian Lab Report Introduction Planarian worms are free-living flatworms that are not parasitic. Planarians have a three-cavity digestive system. Planarians are usually either carnivorous or scavengers. Planarians may eat other living‚ as well as dead‚ invertebrates‚ detritus or decaying organic matter. Planarians do not realize that are eating a lot‚ and can over eat resulting in death. Most planarians are freshwater forms that can

Bacterial Transformation Lab Report Backround: The plasmid pGLO contains an antibiotic-resistance gene‚ ampR‚ and the GFP gene is regulated by the control region of the ara operon. Ampicillin is an antibiotic that kills E. coli‚ so if E. coli‚ so if E. coli cells contain the ampicillin-resistance gene‚ the cells can survive exposure to ampicillin since the ampicillin-resistance gene encodes an enzyme that inactivates the antibiotic. Thus‚ transformed E. coli cells containing ampicillin-resistance

ES184 Mechanics‚ Structures and Thermodynamics Inertia Laboratory Report Summary The objective of this report is to find the Moment of Inertia of a disc by means of investigating the use of rotational motion. We then used the results of the experiments to plot a graph showing the relationship between the mass of the weight with the time taken by load to pass the distance of length of the string. Three different size discs were used in these experiments to determine the influence the

[Name] [Teacher] [Course] [Date] Catalase Lab Report An enzyme is something that helps to speed up a chemical reaction. The enzyme changes from reaction to reaction‚ but it always has the same impact. However‚ certain variables may cause the enzyme to have a more or less significant impact on the speed of each reaction. One of these variables that changes the effectiveness of an enzyme is temperature. There is an optimal functioning temperature for each enzyme in each reaction‚ depending on

Zach Sexton December 4‚ 2014 Bot 121 Lab Coleus Lab Report 1. A cutting can form an entire new plant if cutting being used has a meristem. If the cutting has no meristem‚ mitosis will not occur and you will end up with a dead piece of plant material. In order to successfully grow a new plant through a cutting‚ your plant must have adventitious root growth which in order to deliver water and nutrients to the plant. Adventitious roots are created through cell potency where cells differentiate. The
