concentration to an area of lower concentration‚ through a semipermeable membrane. We put the potatoes in different solutions with a different amount of sucrose in each solution‚ starting from 0.0 to 0.6. My hypothesis was that in from the 0.0 to 0.3 the weight of the potatoes will shrink and from 0.4 to 0.6 the potatoes will grow. If the potatoes absorb the sucrose and gain weight then they are hypotonic. But if the potatoes shrink then they are hypertonic. If they don’t change in size at all they are isotonic

Water is the smallest with 3 atoms‚ then glucose with 24 atoms‚ than sucrose with about 48 atoms‚ and then finally starch.

Panacetin‚ is originally produced by. Extraction of the chemicals Sucrose‚ Aspirin‚ and an Unknown substance is tested to determine the legitimacy of the label and drug. Theory: The percent composition is calculated for accuracy and to conclude the “label is accurate”. The formula for the percent composition is adding the sums of all the extracts‚ then dividing the total sum by each of the three (3) individual extract; Sucrose‚ Aspirin‚ Unknown. By separating

For this lab the following materials were needed to complete the experiments in test 1 for proteins: Di water‚ ev milk‚ 50% egg solution‚ 1% sucrose‚ 4 test tubes‚ 1 test tube rate‚ safety glasses‚ pipets and the reagent solution. For test 2 for starches the following materials were used: Di water‚ 1% starch solution‚ onion juice‚ sucrose solution‚ iodine reagent‚ 4 test tubes‚ test tube rack and pipets. In test 1 and test 2 each solution was placed in a separate test tube with the corresponding

The opening of the tube was covered with a cotton ball to prevent oxygen from entering. The set-ups were then observed every five minutes for thirty minutes. The volume and rate of carbon dioxide (CO2) evolved was calculated and recorded. Results showed that set-up 2 which contained the sucrose substrate yielded the highest rate of cellular

Fermentation Lab: Conclusion & Evaluation of the Effect of Type of Carbohydrate on Amount of CO2 Produced IB Biology/Topic: 3.7 05 February 2013 Question: Which type of carbohydrate‚ glucose‚ sucrose‚ or starch‚ will produce the greatest amount of fermentation over the class period? Why? Hypothesis: If the carbohydrate starch is added to the set up of yeast‚ then it will create the greatest amount of fermentation because starch is a polysaccharides
