FEEDING HABITS OF DROSOPHILA MUTANTS Name: Joshua Suidgeest Student ID: U3081023 Tutorial Day and Time: Friday’s at 14:30 (until 17:30) Tutor’s Name: Sandy I declare that the written work presented in this report is my own work. Abstract As a pre-introduction to this lab report as a whole‚ this experiment was carried out to answer some questions that may come to mind when “Drosophila” and “Inheritance” are put in the same sentence. The Drosophila insect is a species of

Drosophila Melanogaster Introduction Drosophila mature through complete metamorphosis‚ as do all members of the order Diptera. [5] Diptera are commonly known as (true: having two wings) flies and include many familiar insects such as mosquitoes‚ black flies‚ midges‚ fruit flies‚ and house flies. [3] Drosophila melanogaster are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled‚ they have a short life cycle

Title:The Chromatography Process of Expo Markers Abstract:This experiment is to uncover whether or not the Expo Markers are homogeneous or heterogeneous mixtures. The experiment will conduct filter paper being slightly submerged in a container of water and inspected for pigmentation changes. In the experiment the pigments will rise up the filter paper once exposed to the water (solvent). After the experiment‚ it concludes that the mixture is a homogeneous mixture due to the chemical

Autosomal Inheritance of Wrinkled and black Mutations in Drosophila melanogaster Abstract Homozygous Wrinkled virgin females and homozygous black male Drosophila melanogaster‚ were crossed. Mutations were located on chromosome two and three respectively. The F1 generation‚ all Wrinkled and black‚ was inbred yielding and F2 generation. A phenotypic ratio of 9:3:3:1 was hypothesized with wrinkled wings and wild type body: wrinkled wings and black body: wild type wings and body wing: wild type wings

Chromatography (Greek for ‘colour writing’) is used to describe various methods applied to separate mixtures (referred to as the sample of the experiment) with great accuracy to analyze them. By using chromatography we can manipulate these to move at different speeds through the system‚ thus separating them. Chromatography is necessary in chemical industries‚ as well as bio processing companies. Chromatography can be: 1. analytical: used to measure ratios of analytes(substance in simpler forms)

Paper chromatography is one of the easiest methods of chromatography. It is a method of planar chromatography (stationary phase is in form of a plane). Paper chromatography follows the basic principle of chromatography‚ which states that substances or components are distributed in between the stationary phase and the mobile phase. It is an analytical technique‚ where only a small amount of a sample is used for separating and identifying its components. Like any other method of chromatography‚ paper

Ang Group 1 2C Pharmacy Organic Chemistry Laboratory ABSTRACT In this experiment‚ the techniques column and thin layer chromatography was used to separate and determine the purity of the colored components of siling labuyo and malunggay leaves. The results obtained relied on differential solubilities and adsorptivities of the components to

the Doll Test OR Eye Color Experiment resonated more with children is because children are brought up in discrimination house hold. Doll test told that how equal size the dolls were except for their color‚ to test children’s racial perceptions. Their subjects‚ where at least the children between the ages of three to seven‚ were asked to identify both the race of the dolls and which color doll they prefer. Eye Color Experiment talks about on how children treated each other by eye color instead of

Experiments and war are not often thought of being similar. Experiments are thought to be sterile‚ civilianized‚ and controlled; with men in pristine white coats rushing about carrying test tubes and clipboards. On the other hand‚ war is chaotic and anarchic; filled with disease‚ death‚ and suffering. War is bloodshed and loss; while experiments are organized and precise. Psychological experiments can be used to simulate warlike tendencies and behaviors. The Milgram Obedience Experiment‚ tests how

Chromatography – Analyzing Analgesics by TLC and Isolation of β-Carotene by Column Chromatography Introduction/Background: Flavonoids are an important group of additives that can be defined as pure substances either natural‚ extracted from raw materials or synthetic. Chromatography is the separation of two or more compounds or ions caused by their molecular interactions with two phases – one moving and one stationary (Weldegirma 2012). Three types of chromatography are used
