Introduction: To achieve genetic experiments with haploid organisms‚ genetic strains of different genotypes must be crossed from one another. Following fertilization and meiosis‚ the meiotic products can be analyzed as the ascomycete fungus‚ Sordaria fimicola. Sordaria can be used as a model to study meiotic segregation. The trait followed was the ascospore color. Ascospore color is a single gene trait therefore it is easily observed under a light microspore. Which allele is dominant is very tough

Exocytosis Lab Report Rough Draft Abstract: In Paramecium caudatum‚ trichocysts are 10^3 secretory vesicles that are released from the cytoplasm. We first observed how the presence of Alcian blue dye triggers normal secretion of trichocysts‚ and we then tested four different hypotheses in order to determine how the presence of Ca++ ions in the extracellular and intracellular environment affects the secretion of trichocysts. Our first our hypothesis tested whether extracellular calcium is

Formal Lab Report | Chemistry | | Student name: Sara Hattar Grade: 10 ”C” | | Teacher: Christine Ziadat | | | Title: Investigating the effects of changing the concentration of an acid on the rate of reaction between HCl and Magnesium. Aim: In this experiment we are going to see the effects of using three different concentrations of HCl when added to Magnesium metal on the rate of reaction. Hypothesis: If the concentration of the acid increased in reaction between HCl (the acid)

Carbohydrate Lab Report Introduction Qualitative identification of a substance is of significant importance in chemistry. Physical constants such as melting points have traditionally been used by organic chemistry for identification of unknown compounds. As for inorganic substances‚ the precipitation of a solid‚ results of a flame test‚ or the formation of a colored substance could all be keys to identifying a sample. Chromatography and spectra are amongst the newer techniques

Introduction In this lab‚ the purpose was to verify Hess’s Law. Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The enthalpy of reaction‚ ΔHrxn is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant pressure in the reaction. The change represents the difference in enthalpy of the products and the reactants and is independent of the steps

Measures of Flexibility and Their Correlations to Sit-and-Reach and Modified Sit-and-Reach Tests Jacob Palmer University of Puget Sound March 3rd‚ 2015 Measures of Flexibility and Their Correlations to Sit-and-Reach and Modified Sit-and-Reach Tests INTRODUCTION Flexibility can be defined as the capability of something to bend easily without breaking. The flexibility of a person is commonly measured during fitness tests‚ and the most frequently used test of a person’s flexibility is the sit-and-reach

Meiosis and Genetic Diversity in Sordaria 979554296 Biology 110 Lab Introduction: In Israel there exists multiple spots in the mountains called Evolution Canyons‚ which are all located between a southern facing slope (SFS) and a northern facing slope (NFS). What’s particularly interesting about these locations is that despite the two slopes being on opposite sides of a small canyon‚ they exhibit extremely contrasting conditions. The SFS receives multiple times the UV radiation from the sun

Name: Danielle Title: Unknown Lab Report Introduction: There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics. The experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by Dr. Honer. The appropriate tests were prepared and applied. The

rate of germination didn’t really vary between the number of paper towels throughout the experiment. Most of the seeds had germinated in the paper towels. The one outlier that was strange was the one paper towels. Only 14 of the 15 seeds germinated in that group. The difference that we could observation was the healthiness of the plants. IV. Conclusion Paragraph 1 Recap (Evidence): The purpose of our lab was to see if the amount paper towels would affect the germination of the seeds. My hypothesis
