    Materials and Method: The experiment was started by adding 10ml of the water-yeast solution to each fermentation tube. There were 12 fermentation tubes that needed 10ml of the solution. Then‚ 3 grams of Sucrose were added to the positive control fermentation tubes. For two of the fermentation tubes‚ 1 gram of Truvia was added‚ and for another two fermentation tubes‚ there was 2 grams of Truvia added. Then‚ 3 grams of Truvia were added into two more tubes

    percent. For the 0.2‚ 0.4‚ 0.6 0.8‚ and 1.0 Moles of sucrose solutions‚ the bag gained mass. The water had to diffuse across the membrane into the bag to space out the sucrose molecules because the beaker contained no sucrose. The sucrose was unable to diffuse across the dialysis tubing because the molecules were too large for the pores (as referenced in the previous paragraph). This part experiences osmosis because only the water‚ not the sucrose‚ diffused across the membrane to close the gap between

    3. Describe the differences between animal and plant cells. Although plant and animal cells both have mitochondria‚ cytoplasm‚ and ribosomes they differ in many ways. Animal cells do not have a cell wall and are round with irregular shapes. Centrioles are also present in all animal cells‚ as well as most eukaryotic cells. Plant cells only have centrioles if they are in the lower plant species. Both types of cells have vacuoles‚ but their functions are quite different. The purpose of vacuoles in

    cylinder to measure 1 mL of the 1.0 M sucrose solution and use the “DW” pipet to add 4 mL of distilled water to test tube “b”‚ which is now a .2 M solution. Then use the graduated cylinder to measure 2 mL of 1.0 M sucrose solution and add 3 mL of distilled water to test tube “c”‚ which this creates a .4 M solution. Measure 3 mL of 1.0 M sucrose and 2 mL of distilled water to test tube “d”‚ which then creates the .6 M solution. Measure 4 mL of the 1.0 M sucrose solution and 1 mL of distilled water

    of time it would take to get to the result of fermentation with different sugars. This fermentation rate was calculated with water displacement using pipettes to discover the span of time before the release of air bubbles known as Carbon Dioxide. Sucrose had the highest fermentation rate in comparison to all of the other sugars that were tested. The results confirm the capability of cells when it comes to cellular respiration despite the lack of oxygen. Introduction Adenosine triphosphate‚ known

    Phenol | C6H5OH | 43.0 | 7.40 | 181.0 | 3.56 | Use the previous formula and the constant from Table 1 to calculate the temperature at which a solution of 50 grams of sucrose (C12H22O11) in 400 grams of water will freeze. The molecular weight of sucrose is 12(12.01) + 22(1.01) + 11(16.00) = 342.34 g/mole so‚ the number of moles of sucrose is and the concentration of the solution in moles per kilogram of water is By taking the freezing point constant for water as 1.86 from Table and then substituting

(3) There are two different types of information that can be obtained from research. The types of information that can be obtained are quantitative and qualitative data. Research results are considered qualitative when the results can be answered with a simple statement of yes or no. Qualitative data does not attempt to give a numerical value; instead

Place approximately one third of a tube of distilled water in the first‚ and an equal volume of each of a series of sucrose solutions of different strengths and (molarities) in the remainder. Each tube should be firmly stoppered. 2. Using a cork borer and a razor blade‚ prepare six solid cylinders of potato. Each cylinder should be approximately 10mm in diameter
