F60B01 CELLS AND MOLECULES PRACTICAL 2: DETERMINATION OF WATER POTENTIAL OF POTATO STRIPS LABORATORY REPORT REPORT BY: - CHIN YI JING (024492), CHOONG XIN YUN (024423), LEE GAH NI (024320), RENAD SADIG (024598), and SAI SAMHARINI D/O VIGNESWARAN (024429) Introduction In order for the cells to be able to maintain their metabolic functions, various biological molecules need to pass into and out of the cell. This can be achieved by transport processes, which can be broadly classified into passive
1. Title: Determination of Vitamin C concentration in water relative to temperature variations. 2. Introduction Vitamin C or in other terms ascorbic acid or ascorbate is a substance which is soluble in water. It is found in a varying concentrations in vegetables and fruits. Vitamin C is a vital nutrient for human constitution, however it cannot be produced by humans on the contrary to animals with few exceptions. So, humans need in certain amounts of Vitamin C in their daily diet. Vitamin C is
gloves • Avoid aerosols • Care must be taken when heat fixing slide Materials • Glass slide • Loops • Sterile normal saline • Burner • Stains Method i. Add one drop of sterile normal saline or distilled water on a clean glass slide ii. With a sterile loop add 1 colony of bacterial growth to the water,
Name- Aashish Upadhyay Integrated science II Mr. Montbriand Lab Report: Separating Mixture Purpose: The purpose of this experiment is to separate mixture of sand, Iron filings, and salt. Also, to ascertain mass of each object after separating them. Background information:- Materials get separated according to the differences they have in their physical properties. In separating mixtures you should avoid any chemical change so, you will not lost any of your product and the experiment will
Specific goals were to achieve 10-12% acidity using constructed lab scale production facilities and to characterize the species of vinegar bacteria used in acetification. Vinegar is the product made from the conversion of ethyl alcohol to acetic acid by a genus of bacteria, Acetobacter. Therefore, vinegar can be produced from any alcoholic material from alcohol-water mixtures to various fruit wines. Its colour and aroma are greatly dependent on the material from
parameters chosen for the optimization were Dissolution efficiency at 10 min and In-vitro dispersion time. Data analysis was carried out by multiple linear regression analysis. Differential Scanning Calorimetry (DSC) and Attenuated total reflection (ATR) reports shown that there is no interaction between drug and excipients. Results: Four optimized formulations F1 to F4 are selected from the numerical optimization technique. The prepared formulations were evaluated for different pre-compression and post-compression
This is called “pump prime”. There are distilled water bottles located at the bottom of the analyser and once the command is entered from the keyboard to perform the wash, the analyser will automatically wash each probe used to take the samples and the reagents. The internal parts are also
