causing the body to not have enough acids in the urine. These factors are all very different‚ but are interconnected because an imbalance in any of these factors can lead to imbalances in other areas as well (Wise‚ 2010). The importance of this lab is to analyze factors that may affect urine concentration‚ pH‚ and rate of production (flow rate) though multiple scenarios over a period of 60 minutes. My hypothesis for the urine analysis experiment is that the urine volumes will increase because

Investigating Effects of duration of heating on permeability of beetroot cell membrane Introduction: Cell membranes contain many different types of molecules which have different roles in the overall structure of the membrane. Phospholipids form a bilayer‚ which is the basic structure of the membrane. Their non-polar tails form a barrier to most water soluble substances. Membrane proteins serves as channels for transport of metabolites‚ some act as enzymes or carriers‚ while some are receptors

Lab Report Title: * Color reaction of starch when mixed with Iodine solution Introduction: Statement: * How would the varying solutions react when introduced with the Iodine solution? Hypothesis: * If a solution is rich in starch then it will react with iodine solution and change to a bluish-black color (looks Brown) Materials: Items: * 8 test tubes‚ pipet‚ iodine‚ onion juice‚ potato juice‚ sucrose solution‚ glucose solution‚ distilled water‚ fructose solution‚ starch solution

experimental pH values starting at value 2 through value 10 (all even #’s) 3. Transferred 25 ml of the substrate B into the cuvette using the pipette. 4. Referring to the timer to determine when 1 minute has passed transferred 5 ml of enzyme B into the cuvette and quickly into the sample holder of the spectrophotometer. 5. Recorded the absorption value at the 1 minute mark 6. Started a new experiment by removing the cuvette from the spectrophotometer and clicking the “New Experiment” button to repeat and continue the steps for the remaining pH values

water with no chlorine. Clean an area of space you think is suitable‚ preferably lab tables. Take out 5 beakers. Take out an electric mass scale. Turn on electric mass scale (power button) and place a beaker on top of the scale. Make sure to only measure one beaker at a time. Wait till the digits on the screen slow down and stop at a number. The number it stopped at‚ that is the number you will right down in your lab book (that you will get out) as scrap notes. After you have measured each beaker

Name: Mugabe Rodrigue Class: Grade 11B Subject: Biology Topic: DNA Extraction From Onion Date: 20/1/2014 Introduction: DNA‚ or deoxyribonucleic acid‚ is the hereditary material in organisms. Nearly every cell in an organism has the same DNA. Most DNA is located in the cell nucleus.The information in DNA is stored as a code made up of four chemical bases: adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). The order‚ or sequence‚ of these bases determines the information available for

they will become to the female and predators. This will lead to the decrease of population and changes in the population. The frequency for the color fishes will decrease as time passes. Methods For this particular experiment we had two different lab tests. For the first part of the experiment it was necessary to use a computer and log on the http://www.pbs.org/wgbh.evolution/educators/lessons/lesson4/act2.html and lunch the Sec and the Single Guppy web activity.
