best fabric for science laboratory clothing. (Final Report) Abstract: This experiment looked at the effectiveness of cotton‚ wool and polyester to come up with a hypothesis to which material would be the best used in a lab coat. After the hypothesis was made an experiment was done on the 3 materials‚ to find out which material is the best to use in a lab coat. The results of the experiment were that wool was the best material to be used in a lab coat. Introduction: Scientists and students working

optimize the ethylene production at developmental transitions as well as during stress response. Ethylene is derived from the amino acid methionine‚ which in the first step is converted to S-adenosyl-methionine (AdoMet) by AdoMet synthetase3‚4. The 1-Aminocyclopropane-1-Carboxylic acid Synthase (ACS) catalyzes the conversion of AdoMet to 1-aminocyclopropane-1-carboxylic acid (ACC)5‚ which is the rate-limiting step in ethylene biosynthesis. ACC is then converted to ethylene by ACC oxidase (ACO)‚ a member

The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda

Introduction Human cilia play a critical part in human processes. Human cilia are hair-like projections that extend from the surface of a cell. Cilia are capable of rhythmic motion and acts together from separate strands so that the cell is capable of movement. Flagella are a whip-like structure that is found in cells as well that allow for the movement of the cell. Human cilia are characterized as having “metachronal rhythm" and this means is a rhythm that "changes time" to produce wave. The beating

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

AP Biology Lab: Catalase (Enzymes) Abstract In this laboratory exercise‚ studies of enzyme catalase‚ which accelerates the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. The laboratory was also conducted in association with a second laboratory that measured the effects of an inhibitor on the enzymes. Changes in temperature and pH along with Substrate Concentration and Enzyme

The Microscope Lab Brandy Talley PRCC Biology Lab Online June 13‚ 2013 Purpose: The purpose of this lab is to learn about different types of microscopes that we use today‚ learn the parts of the microscope‚ and how to properly use a microscope by exploring various slides. Materials: *Microscope *Letter “e” slide *Onion root slide *Bacterial capsule slide *Cheek smear slide Lab Notes: 1.What is the difference between a compound

Hugh Kim Lab Report: Stoichiometry Lab 1. Prelab Part1. 1) Create no waste = The principle that encourages chemists to not create waste at the first place rather than cleaning it up afterwards effectively shifts the chemistry more environmentally conscious‚ as creating no waste would make the experiment efficient; the reactants will be reduced to only the essential ones and the product will be maximized‚ a change that would make the experiment economic. Also‚ if chemists aim to

Introduction: Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans‚ mitosis produces somatic cells that are diploid‚ which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that

Introduction This report will investigate the six essential nutrients required in our diet. The report will provide the function of each nutrient and explore why they are vital for the body. Carbohydrates Carbohydrates are the most important nutrient for the body as it is the largest possible source of energy. Carbohydrate supplies the body with energy‚ which allows the brain to function more effectively and allows organs to operate sufficiently. When the body has energy this allows each
