Three test tubes were filled with 5 mL of A‚ B‚ and C‚ respectively. 10 drops of mammal blood was added to each of these and mixed. The transparency and translucency of these tubes was tested. The solutions in the opaque tubes were placed on a slide with a drop of blood and observed under a microscope and compared to a control slide with just a drop of blood. Sketches of the observations

Abstract: In this Lab we used the chemical DPIP to detect the rate of succinate broken down by the mitochondrial solution. We detected the amount of DPIP in the solution with a spectrophotometer and measuring the absorbance of light at the 600nm range. DPIP is a useful chemical to use in this experiment because it goes from a blue color when oxidized to a colorless liquid (Ogura‚ 281)‚ this is due to the hydrogen ions and electrons released during the transitional step between succinate and fumarate

Kathleen Kramas Cells and Heredity Lab Tuesday 2:00-4:50 22 OCTOBER 2012 Membrane Permeability Decreases as Molecular Size Increases Introduction: Red blood cells are vital to organisms functioning properly. They are microscopic cells that carry oxygen from the lungs to all the tissues throughout the body. Upon transporting oxygen‚ red blood cells also exports waste‚ such as carbon dioxide‚ to the lungs where it can be expelled. Red blood cells are made up of hemoglobin which is surrounded by a

Evolution Lab Report Marcos Chapa July 3‚ 2013 BIO 101 Rebecca Avants The purpose of the lab I have conducted is to analyze how altering the finch’s environment would affect the evolution of the finches by isolating each population of finches from each other‚ placing them each on a different island. This influence on the species by the environment is called allopatric speciation. One population of the finches that are located Darwin Island‚ which is 1 km‚ and the other population of finches

Physics Lab report Aammar Paracha Section MX Feb 6th 2015 OPTICS Abstract: This experiment revolves around using light rays and lenses. The experiment also discusses different properties of light rays. This experiment uses different lenses and measurements to produce images and observes different techniques to obtain the image position. Question and Answers: 1. Use your data to verify the Law of Reflection and then use Snell’s Law to calculate

’Neil 2002). The particular conditions that had to exist for this to apply were that the population had no mutation‚ had no natural selection‚ was a large population‚ had only random mating‚ and had no migration. For the cases to follow later in the lab‚ Cases 1 and 2 exemplify Hardy-Weinberg conditions. All of the others either have selection or not enough members in the population‚ which will be the most-closely observed

facultative aerobe prefers oxygen but it is not necessary for growth. Many of these microorganisms will grow at the top of the tube‚ but will also be dispersed throughout as well. B. Discuss the temperature requirements of the organisms (you grew) in this lab. Both Staphylococcus epidermis and Lactobacillus acidophilus are mesophiles. Mesophiles grow best between 25- 45 degrees Celsius (Alonzo‚ n.d.). In this experiment both bacteria have grown easily at a maintained room temperature of 26 Celsius. C

Introduction The purpose of this lab was to calculate and determine the optimal dosage of ultraviolet (UV) light to expose Saccharomyces cerevisiae (S. cerevisiae) to that would result in a survival rate of 20-40%. Saccharomyces cerevisiae commonly referred to as baker’s yeast is a single-celled eukaryote. Yeast is capable of growing as either a haploid or a diploid cell. The diploid cell can reproduce mitotically or sporulate‚ a process initiating meiosis and forming an ascus with four spores (Sacchromyces
