Cell Homeostasis Virtual Lab The fluid in the beaker represents what? The fluid outside the cell The fluid in the dialysis tubing represents what? The fluid inside the cell Beaker A consists of what?` 1000mL Beaker A will serves as the _____ for the experiment control Beaker B consists of how much water and how much sugar? 0g sugar and 1000mL water Beaker C consists of how much water and how much sugar? 50g sugar and 1000mL water Beaker D consists of how much water and how much sugar? 100g sugar and 1000mL water Beaker E consists of how much water and how much sugar? 150g sugar and 1000mL water The dialysis tubes will remain in each beaker for how long? 24 hours Beaker solution % sugar A=0%, B=0%, C=5%, D=10%, E=15% Dialysis tube solution % sugar A=0%, B=10%, C=10%, D=10%, E=10% Initial mass A=17.59g, B=8.75g, C=11.24g, D=10.71g, E=18.50g Final mass A=17.66g, B=10.40g, C=10.62g, D=10.30g, E=15.60g Amount of mass gained (+) or lost (-) A=+.07g, B=+1.65g, C=-.62g, D=-.41g, E=-2.45g In the lab, what are 4 variables that remained constant throughout amount in the tubes, amount of time, amount of water, temperature the lab In the lab, which variable is the dependent variable The mosses In the lab, which variable is independent The % sugar in the beaker If the percent concentration is greater in the fluid outside the cell than inside the cell, how will the water flow? The water will flow into the cell This means the solution would be ______ hypotonic Which tube(s) did this happen to? B If the percent concentration is equal both inside and outside a cell, how will the water flow? nowhere This means the solution would be _____ isotonic Which tube(s) did this happen to? A, C If the percent concentration is greater in the fluid inside the cell than outside the cell, how will the water flow? out of the cell This means the solution would be _____ hypertonic Which tube(s) did this happen to? D, E Which dialysis tube(s) had little or no change in mass after the 24-hour period? Explain why this happened. A, C. This happened because there was no sugar in the solution and it provided something to control all of the other results too 1/1
