Rachel Bohnenberger Professor Van Doorn ENVS 150-002 27 April 2015 GMOs Lab Report Introduction As the population of Earth increases exponentially‚ so does the demand for more food. One of the solutions to the question of how more food can be produced is Genetically Modified Organisms‚ or GMOs. There is an ongoing debate about whether or not GMOs are more beneficial or harmful to society. Some of the benefits to GMOs are: growing plants‚ such as corn‚ that are resistant to weeds and pests‚ larger

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

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

nearly colorless (2-5 mL). Suck dry for 10 minutes‚ then air dry for a further hour. Weigh the product and calculate %yield. Dissolve the crude product in a hot mixture of 2 mL ethanol and 1.3 mL chloroform (do not boil the resulting solution). Gravity filter through a Kimwipe plug in a Pasteur pipet. Cool the filtrate slowly to room temperature‚ then cool further in an ice bath. Isolate the product by suction filtration‚ wash with cold ethanol/H2O (20/1 v/v)‚ and suck

Thirdly‚ □(→┬DE ) Represents the 5 years in which the Astronouts will spend collecting data on the planet‚ that’s why theres no acceleration‚ velocity or distance travel‚ only time. After that‚ the astronouts will repeat the same trip back to Earth‚ starting with the acceleration through □(→┬EF ) leaving Kepteyn b‚ to then travel at a constant speed from □(→┬FG ) untill they reach the asteroid belt and desaccelerate through □(→┬GH ) and arriving Earth

Paper cone Lab Variables: - Independent: The independent variable is the diameter of the paper cone’s base. - Dependant: The time will be measured to see how long does it take the paper cone to land on the floor. For this measurement we are going to use a stopwatch and the time measured is going to depend on our reaction time. - Controlled: The mass of the paper cone and also the height from which we are going to drop the paper cone are constant. The acceleration due to gravity will be

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

Natasha Tenen Lab: Thursday (3-6 pm) OSMOSIS LAB REPORT INTRODUCTION Osmosis is a special type of diffusion where water molecules move down a concentration gradient across a cell membrane. The solute (dissolved substance) concentration affects the rate of osmosis causing it either to speed the process up or slow it down. Based on this‚ how does different concentrations of sucrose affect the rate of osmosis? If sucrose concentration increases in the selectivity-permeable baggies‚ then the
