Meiossis and Genetic Diversity in Sordaria Meiosis and Genetic Diversity in the Model Organism‚ Sordaria. By: Katie Fiorillo BIO110 Lab TA: Lauren Smith October 30‚ 2012 A. INTRODUCTION: In this lab‚ the organism Sordaria fimicola was used to explore factors contributing to genetic evolution of sexual reproduction. These organisms are found in “Evolution Canyons‚” which occur when two mountain slopes with very different climatic conditions congregate with a comparatively small valley

The Microscope Lab Brandy Talley PRCC Biology Lab Online June 13‚ 2013 Purpose: The purpose of this lab is to learn about different types of microscopes that we use today‚ learn the parts of the microscope‚ and how to properly use a microscope by exploring various slides. Materials: *Microscope *Letter “e” slide *Onion root slide *Bacterial capsule slide *Cheek smear slide Lab Notes: 1.What is the difference between a compound

Mr. Mihordea Motion of Atoms and Molecules lab summary In this lab the standard heat of combustion of magnesium was calculated by using the calorimeter. Also‚ the point of combustion of magnesium was to see how much heat would be released from fireworks such as sparklers. The concept of this lab was to find the difference in temperature from the beginning to end of combustion of magnesium and calculate the standard heat

Ketchup Lab Report Problem: People visiting fast food restaurants complained that ketchup was dripping onto their fingers and clothes. What could we do to insure that the ketchup will not drop all over the customers? Hypothesis: If I put one ketchup packet in a hotter bath then it will move faster down the styrofoam plate. Independent Variable: The temperature Dependent Variable: The viscosity of the ketchup’s “runniness” Constants: The type of ketchup

Effects of Electrical Stimuli and Injected Reagents on Frog Hearts Melissa Higdon Section 05‚ Group 01 November 19‚ 2013 Introduction: The heart is a very complex muscle for all species. It is responsible for sending oxygenated blood throughout the body as well as sending deoxygenated blood to the lungs‚ and continuously circulate this way for as long as we are alive. Many things can be effected‚ for example how fast the heart beats or how much

source. The slit was pointed towards the source‚ and the spectroscope was shifted until the spectrum was clearly visible. The appearance of the spectrum from the fluorescent light source was recorded. A discharge tube apparatus was retrieved from a lab cart for demonstration. A hydrogen discharge tube was inserted into the discharge tube apparatus with the spring loaded end first‚ followed by the non-spring loaded end. The discharge tube apparatus was plugged into the outlet. The hydrogen discharge

Maria Martinez Anatomy and physiology II TTH 2:20 “Demonstrating the Importance of Surfactant: Lab Report” Introduction Surfactant is an essential component for the respiratory system to function properly. This experiment was administrated to help us understand better the role of surfactant in the alveolar system. Surfactant is a detergent-like substance produced by the Type II alveolar cells in the alveoli. Surfactant is produced to make it easier for people to breath by reducing the surface

The temperature of water was determined by a thermometer. 1 cm stripped ends of the wires was hooked into the input posts on the back of the impendence converter. Lab tutor module was started after. B. Baseline heart rate The top of the container was covered with foil and the animal was allowed to sit quietly for 10 min. The trace was examined by pressing start. After that the baseline or the controlled

the highest amount rise‚ which will show us the optimal color of light for photosynthesis. These different colors of light included blue‚ red‚ green‚ fluorescent‚ regular light‚ and classroom light. The classroom light was our control cup during the lab. Before we conducted our experiment‚ the class learned about the photosynthetic process of‚ not only spinach discs‚ but plants in general. As I did more research on photosynthesis‚ the Calvin Cycle‚ wavelengths and pigments required for a proper equation
