Get Charged Up Lab Report Abstract Get Charged Up Magnesium ribbon was reacted with Hydrochloric acid in three different experiments to determine the charge on a metal ion. After running multiple tests in the three different procedures‚ the Crystallization method proved to be the best method for determining the charge of the metal ion by using mole to mole ratio. Introduction The objective of the Get Charged Up lab was to determine the charge on a metal ion reacting with HCl by determine

solution with the lower concentration is hypotonic. What is the solute concentration of potatoes? We can determine this by conducting an experiment in which involves the process of osmosis. Potatoes are full of sucrose used for energy storage in plants. Sucrose is a carbohydrate found in food. It is a disaccharide‚ with a combination of fructose and glucose. Consumers break sucrose down into two monosaccharides so they can be absorbed more easily into the blood. Sucrose is too large of a molecule

ABSTRACT: Two separate variables were hypothesized and tested within the confines of the experiment on their effects on the productivity of lactase enzyme. The measurement of light absorbance levels of different solutions based on both the concentration of o-nitrophenol (ONP) as well as the pH of the solution tested. To begin with‚ differing concentrations of ONP were tested to find the absorbance levels of ONP. Three different pH values‚ 5‚ 6‚ and 7‚ in solution‚ were tested over a period of 8

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention

Hypothesis: I predict that the leaves taken from the outer area of a shrub have a higher stomatal index (/density) than those taken from the centre of a shrub this are due to light levels. Explanation: Plants have stomata to obtain carbon dioxide from the atmosphere and remove oxygen produced in photosynthesis. During photosynthesis the chloroplasts in the leaf cells synthesize as a result of exposure to light‚ while oxygen is produced as a by-product. As the outer leafs are exposed to higher light

Aqualisa Quartz Case Write up Problem: Aqualisa is suffering from a lack of sales momentum with their new Quartz product line due to a lack strategic promotion. The firm is has boldly attempted to innovate the electric segment of the UK’s shower market. Unfortunately plumbing products have little brand recognition amongst consumers and Aqualisa has a small share of the electric shower market further reducing their new product’s visibility. As electric showers have a reputation of being problematic

Biology textbook- pg. 80 3) Distinguish between the autotrophic and heterotrophic nature of plants and animals. Animals have heterotrophic cells; hence‚ they live off nutrients of other species by eating. Most plants have autotrophic cells‚ which allow them to generate their own food with photosynthesis. 4) Explain the following statement: ‘All living things depend on plants’. As animals are heterotrophs‚ they need to eat other species to survive. If mammals only depended on other mammals‚ there

organic fuel derived from pyruvate-‚ and the electron transport chain - moving electrons through a series of protein complexes to generate ATP (Reece‚ et.al‚ 2011). The process of cellular respiration occurs in the Cytoplasm and the Mitochondria in plants and animals. In this process‚ many more ATP molecules are produced compared to alcoholic fermentation which is a process that releases energy in glucose to generate ATP in the absence of oxygen. Aerobic respiration produces 38 ATP compared to 2 ATP
