The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation‚ the process in which a cell takes up and expresses a new piece of genetic information‚ the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their

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

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

British novelist once wrote‚ “Nobody but he who has felt it‚ can receive what a plaguing thing it is to have a man’s mind torn asunder by two projects of equal strength‚ both obstinately pulling in a contrary direction at the same time.” In the drama Fences‚ August Wilson uses stylistic devices to characterize how the main character‚ Troy Maxson‚ is pulled in conflicting directions by compelling desires‚ ambitions‚ obligations and influences. Wilson purposely creates a play set in the middle of

can survive in extreme environments. Halobacteria are also useful by being a good organism to perform DNA transcription‚ translation‚ and transformation on (Kramer‚ 2006). There are two different types of Halobacteria that are being observed in this lab. The first is NRC-1‚ which is also called the wild type strain. Although the pigmentation of the Halobacteria is caused by the production of the membrane protein‚ bacteriorhodopsin‚ which is a red‚ the wild type strain is pink in color. This pink color

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each

AuthorLastName2 Name: Course: Instructor: Date: ‘Fences’ by Wilson The play has used a number of symbols to develop the overriding theme. The first category of symbols is the trains. It is through Troy that the author brings in Raynell‚ his illegitimate baby‚ for the first time home. Troy comfortably sits with the motherless baby where he once reigned on a porch even though it is currently an unwanted presence. Troy proceeds to sing the song which echoes all the pleas of an individual man begging

A. Avril Crayfish Lab Report November 9‚ 2012 Dr. Marvin Results: Figure 1. Firing Rate of Tonic Receptor in Response to Stretch. The correlation between Firing Rate and Stretch of the slow adapting crayfish receptor for four different sets of data is represented in this figure. The recordings are taken at stretches of 2‚ 4‚ 6‚ 8‚ and 10 mm of the crayfish tail. The best fit lines for the different sets of data are as follows: Ali and Emily- Linear best fit line‚ Dave and Laura- Exponential

Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around
