Abstract Photosynthesis is a food making process for algae and plants. The photosynthesis process rate varies from different wavelengths and intensities of light. This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. The mixtures of DCPIP with water‚ PO4 buffer‚ and chloroplast will be prepared in a number of cuvettes. The cuvettes were tested individually at different wavelengths and intensities to find the optimal rate

essentially due to hydrophobic bounding. Many authors (Pearse et al. 1985; Stoll 1966; Walstra et al. 1985) indicated that whey protein denaturation syneresis rate can influence syneresis rate. Denatured whey protein rate is increased with increasing heat treatment temperature. The observed differences in syneresis can be related to the differences in curds structure that were demonstrated by SEM (Fig. 3). Syneresis rate and the kinetic rate constant k of curds were higher for the gels having larger

Introduction During the course of this lab‚ we explored whether or not certain processed foods contained Genetically Modified Organisms. Genetically modified food is an important subject in the world today. Ever since Flavr Savr came out with their tomatoes grown from genetically modified seeds in 1994 genetically modified foods has become ever more popular amongst distributors of produce (Mestel‚ 2013). The world’s population has grown by around one billion in the last decade (US Bureau of the

the graph meaning that it will produce the biggest flames out of the other two isomers of pentane. If the concentration is low such as 0.5 then you would expect for 1mL of n-pentane to produce more heat‚ hence having a higher heat capacity and a slower reaction rate. Moreover‚ iso-pentane produces less heat as it takes more time for it to react hence ending in a lower enthalpy value but a faster reaction rate because of its bonds being closer to each other. These assumptions are purely made due to the

Abstract An attitude is a representation of an individual ’s degree of like or dislike for an act‚ object or evaluation. This report aims to conclude whether there is a difference between female and male attitudes towards smoking. It is hypothesised that females will have a more positive attitude towards smoking. Questionnaires using a 5 point likert scale will be utilised to measure each participants’ attitude towards smoking through their responses. Results stated there is no significant difference

Sedimentator Lab Introduction: in this lab we will be working with a sedimentator to observe and classify sediments. A sediment is naturally-occurring material that is broken down by processes of weathering and erosion‚ and is subsequently transported by the action of fluids such as wind‚ water‚ or ice. Side One Purpose: to observe and classify sediments Part I 1. Gently shake the sedimentator to loosen the sediments and lay the sedimentator on its side 2. Observe the water

Laboratory safety regulations 1) Corrosive acids and alkali must be treated carefully‚ and be sure not to splash on clothes‚ skin and eyes. While diluting strong sulfuric acid‚ the acid should be poured

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

Ahmad Shrab . Introduction This lab is purposed to familiarize basic equipment and techniques used in the study of microorganisms. In addition‚ learn some basic techniques used in identifying prokaryotes and make and view microscope slides of some common prokaryotes. In this lab ‚ I worked two experiments ‚ the first one is cultivation bacteria "colony "‚ and When microorganisms are cultivated

Procedures: In the first lab‚ seven test tubes were attained and six of them were filled with the solutions that were listed (Na Pyruvate‚ MgSO4‚ NaF‚ Glucose‚ Water‚ and yeast suspension). The last test tube was filled with water. After they were filled with the solutions they were incubated at 37 degrees Celsius for about forty minutes. After the forty minutes passed take the test tubes and measure the height of the bubbles that formed in millimeters. For the second lab‚ attain three beakers‚
