The solutions in the arms of a U-tube are separated at the bottom of the tube by a selectively permeable membrane. The membrane is permeable to iodine & potassium, but not to fructose. Side A is filled with a solution of 20g of fructose, 5g iodine, &60g potassium. Side B is filled with a solution containing 60g potassium, 10g of fructose, & 30g of iodine. Initially the volume of liquid is the same in both arms. Which direction would potassium pass through the membrane (DOK 3)? From Side B to A
Neither direction; the substance is not permitted to pass the membrane
From Side A to B
Back and Forth, between Side A and B ​

Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. which is most likely to result in the greatest amount of error in their scientific experiment? a. one student measures the plant stem widths by using calipers. the other student measures the widths of the same plant stems again by using a different pair of calipers. b. one student measures the plant stem widths by using calipers. the other student types the measurements as they are taken into a computer spreadsheet. c. one student weighs liquids for the experiment by using a calibrated scale. the other student weighs liquids for the experiment by using a different calibrated scale.
