Chromatography Experiment of the Drosophila Eye Pigmentation Pathway Introduction: How can the use of chromatography help explain single gene mutations of the drosophila melanogaster bio-synthetic pigment pathway? This experiment was meant to help connect the mode of inheritance with different eye color mutations and pinpoint where they occur in the pigment pathway. The drosophila eye color is a result of two bio-synthetic eye color pathways‚ this is expressed as a trait or phenotype‚ a multigene

Distillation Objective: To illustrate the use of distillation for separating a mixture of two volatile liquids with different boiling points. Background: Distillation consists of heating a liquid until it vaporizes‚ and then condensing the vapor and collecting it in a separate container. Distillation is used to separate mixtures of liquids that either have different boiling points‚ or that have one component that does not distill. There are many types of distillation‚ each of which has a distinct

The purpose of this analysis is to estimate the optimal number of cashiers that should be kept open in a retail store to minimize costs and‚ consequently‚ maximize profits. To conduct this study‚ we have chosen the largest retailer in the world; Wal-Mart. Everyone has experienced waiting in line‚ whether at a retail store‚ on the phone for technical help‚ at the doctor’s office or in the drive-through lane of a bank. Sometimes‚ it is a pleasant experience‚ but many times it can be extremely frustrating

Why We Love Drone-Based Oil & Gas Inspection {And You Should‚ Too!} Drones equipped with a combination of sensors are revolutionizing the oil and gas inspections. At the moment‚ the drones with thermal imaging‚ photo‚ and video cameras as well as gas sniffers and other sensors are performing a variety of inspection roles. The mobility and sensors allow the drones to analyze the pipelines and other oil and gas facilities for existing and potential defects. A number of energy companies are already

Experiment D: Separation of Alcohols by Fractional Distillation Pre-lab Properties: Propanol‚ butanol‚ methanol Purpose: To separate two alcohols by distillation and analyze results with GC. Do not plug mantle directly into electrical outlet‚ use controller! Use 40/60 mol percent propanol/butanol (no cyclohexane or toluene are used in this lab because they are more toxic) Set up fractional distillation Set heat at highest level to start‚ then turn back down to 60-80% when vapor starts up column

Preparation of Esters Introduction Esters are known for their pleasant smells such as perfumes and artificial flavorings in contained labs. They are formed when a carboxylic acid reacts with alcohol and a strong acid such as a catalyst called sulfuric acid (H2SO4) for this lab. The structural formula for esters can be represented as R-COO-R’. The R and R’ symbolizes different alkyl groups that can be combined to the ester. When naming an ester the first part comes from the alcohol followed

finding research on this topic‚ refer to the library tutorial located at in the Student Success Center. Identify a patient care situation in which you describe how nursing care or approaches to decision-making may differ based upon the educational preparation of the nurse (BSN versus a diploma or ADN degree). Introduction Nurses are prepared in two different educational backgrounds‚ the baccalaureate degree level of nursing and the associate-degree level of nursing. Though they are prepared in two
