(Solved): 1. which beaker contained the cell that became the most flaccid over time? 2. which beaker cont ...

EXPLAMENTAL SETUP Five artificial cells were made with permeable dialinis tubing and the initial weight of ; determined at the beginning of the experiment. Then, each ceil was placed in one of \( f \), each with a different sucrose concentration. The weight of each cell was recordad at i intenvals for 40 minutes. The weicht of each ine we. - Carculate the weight change (oW) over time for each cell Be sure to standardize by subti the initiai weight from the recorded weight Use \( (v) \) or \( (-) \) to indicate weight gained o loss. Record \( \Delta W \) data on the Summary Sheet provided (colurin B) 2. Generally identify each beaker solution as either hypotonic, hypertonic of isotonic (record) columa A on Summary Sheet.). 3. Create a graph that shows how the weicht chanted (4W) over time. Be sure to color-code line as indicated and label with the correct beaker number. (Do NOT Braph the raw dat provided - use the \( \Delta W \) data that youcalculated in Question a1). 4. Answer all questions on the Summary sheet. Anciners must be in complete sentences \( \& \) clearly answer the question. 5. Consider the graph for the cell in Beaker 5. Assume after the 40 minute weighing that the cell was removed from the beaker and placed in another beaker containing less solute than the cell. Predict how the graph (slope) would change during the next several minutes (weighings). Would the cell lose or gain water? Explain why. 6. Calculate the rate of water loss \( (\mathrm{g} / \mathrm{min}) \) during the first 10 minutes for the cell in Beaker 2 . Show your work \& reduce your answer. 7. Calculate the rate of water loss during the last 10 minutes for the cell in Beaker 2 (show your work). How does this rate compare to what was observed during the first 10 minutes. Explain the difference in osmotic rates. Weight Change Over Time Bioloby 1405 OSMOSIS GROUP ASSIGNMENT GROUP MEMBERS: REVIEW QUESTIONS 1. Which beaker contained the cell that became the most flaccid over time? 2. Which beaker contained the cell that became the most turgid over time? 3. In which beaker were water molecules likely moving the slowest across the membrane? Explain why. EXTENDED QUESTIONS 4. How does the weight gain compare between cells in Beakers 3 \& 4 ? Explain how this may be possible. (Be complete-consider the role that steepness plays in affecting osmotic rate).
