Experiment to investigate the effect of concentration of electrolyte on the current of voltaic cell Aim The aim is to identify the relationship between the concentration of H2SO4 solution and the current of Cu-Zn voltaic cell. Hypothesis My hypothesis is that the greater the concentration of sulfuric acid the bigger the current of the voltaic cell. In a voltaic cell‚ chemical energy is concerted to electrical though the oxidation and reduction happen on the electrodes. Current will not flow

POTENTIAL EFFECTS OF DISCRIMINATION. TASK 3: In looking at this task‚ we have already studied the first part of the topic at the beginning of the Unit. Forms of Discriminatory Practice exist‚ in the form of: Prejudice‚ Stereotyping‚ Labelling‚ Bullying‚ Abuse‚ Lack of choice‚ Infringement of Rights‚ and Covert/Overt abuse of Power. Do we accept that these forms of discrimination exist? What do you think……as maybe you do not agree? Discrimination can be understood as damaging the individual

Beet Cell Lab Purpose: The purpose of this Lab was to see how much pressure or stress the beet tissue would hold. Hypothesis: I hypothesize that the higher % of the solvent that the higher the colour intensity will be shown on the ph colour scale. The lower the solvent then the less colour shown. Materials: *Test Tubes (4) *Cork Borer *Beets *Water *1% Acetone *50% Acetone *1% Methanol *50% Methanol Procedure: *Cut 4 uniform cylinders of beet using a cork borer with a 5-mm

The experimental samples for the pH concentration experiment were put together by using a 10ml-graduated cylinder to obtain 4ml of each pH buffer to insert into cuvettes‚ a micropipette was then used to obtain 0.5ml of catechol and 0.5ml of the catechol oxidase. The pH buffer was made first to avoid any denaturation of the catechol oxidase. Our positive control for this experiment was pH 7 because that is the pH level of most cell membranes in the cytoplasm (Whitson‚ 2016.) Our negative controls

ADULT ELECTROLYTE REPLACEMENT PROTOCOLS Standing electrolyte replacement protocols are available for use in adult patients admitted to King Khaled Hospital. Najran‚ Saudi Arabia. The protocols are listed below. SPECIFIC REQUIREMENTS: • Intravenous infusions of electrolytes must be administered with free-flow protected infusion devices (i.e. infusion pump). • Patients must meet the following criteria prior to initiation of the Potassium‚ Magnesium‚ or Phosphorus protocols: o SCr < 2 mg/dL

Cell Biology Lab - Homework 1 Due to the week of Oct. 6-10th This is NOT a lab group project. Do the work individually. You may use any source other than your fellow students. Show your work‚ use your own words and cite all references. 1. (20 points) The HeLa S3 cancer cell line is considered to be “continuous” due to acquired mutations that enable the cells to evade senescence. This property is one of several hallmark characteristics of cancer cell lines. Describe three hallmark characteristics

Task 3 P3 - The potential effects of discrimination There are lots of potential effects related to discrimination. It includes things like disempowerment‚ low self-esteem and self-identity and also marginalisation. I am now going to explain these effects and connect them with a case study. Disempowerment is when a person or group of people may be made to feel less powerful or confident. Some people may try to fight against the discrimination causing an argument but many people do not and they lose

three different Substrate Concentrations (3%‚ 1% and 0.3%) as which one was the fastest to react‚ I hypothesized that the reaction would occur the fastest with the 3% hydrogen peroxide (the highest amount of concentration) because the higher the concentration the more faster the reaction occurs and helps produce or break up the enzyme. After testing all three of my substrate concentrations with 10 trials each‚ my data showed (first graph) that the 3% substrate concentration had the fastest average
