Assignment: Cell Size Exploration Cell Length of one side Area of one side of the cube (l × w) Surface area (area of one side × 6 sides) Volume (l × w × h) Surface area / volume Ratio of surface area to volume (for example, 5:1) A 1 cm B 2 cm C 3 cm Refer to your data table to answer these questions. 1. What happens to the ratio of surface area to volume as the cell size increases without the cell changing shape? 2. What does a surface area/volume ratio of 6:1 mean for the cell’s ability to get the materials it needs that move across its surface? 3. What does a surface area/volume ratio of 3:1 mean for a cell’s ability to get materials across its membrane, compared to the cell with a ratio of 6:1? could you also put up a picture of the table thing it would help a lot, and if you do I will up the points.

Astudent made a graph plotting the progress of a reaction over time. the student forgot to label the y-axis of the graph. a graph is shown with two graph lines. one graph line starts at a higher position on the y axis and slopes downwards towards the right. the other graph line starts at a lower position on the y axis and slopes upwards towards the right. the two graph lines stop short of intersecting each other and continue as separate lines which gradually become straight and parallel to the x axis. a vertical line is shown at a point where the two graph lines finally became parallel to the x axis. this vertical line is labeled equilibrium. the title on the x axis is time and an arrow pointing towards the right is shown above time. the title on the y axis is left blank. what best explains the label that the student should use on the y-axis? amount, because as the amount of product decreases, the amount of reactant increases over time. reaction rate, because forward and backward reaction become equal at equilibrium. amount, because the amounts of reactants and products become constant after equilibrium is reached. reaction rate, as the rate of forward reaction increases and rate of backward reaction decreases over time.
