Dialysis tubing is permeable to water molecules but not sucrose. Four dialysis tubes are half filled with 5 percent, 10 percent, 20 percent, and 40 percent sucrose solutions, respectively, and two dialysis tubes are half filledwith distilled water. The dialysis tubes are all sealed at both ends, and the initial masses are determined. Five dialysistubes are placed into beakers containing distilled water, and the sixth dialysis tube, containing distilled water, isplaced into a 40 percent sucrose solution. The masses of the dialysis tubes are recorded at 30-minute intervals for90 minutes, as shown in the table below. Show

B) Will organisms living in polluted environments exhibit detrimental effects from an increased permeability of their cellular membranes.
Which of the following identifies the treatment group most likely to have provided an unreliable estimate of the mean?the estimate appears unreliable? Treatment group II; it has a lower than expected mean absorbance and the largest standard error of the mean.
Which of the following results best refutes the alternative hypothesis that selective permeability is a consequence of the cell wall?Which of the following results best refutes the alternative hypothesis that selective permeability is a consequence of the cell wall?

Which of the following best explains why GFP might exhibit a bright green?Which of the following best explains why GFP* might exhibit a bright green fluorescence in alkaline conditions but not in acidic conditions? Addition of an H+ to GFP* at acidic pH changes the shape of the protein, preventing fluorescence.
