Part B Imagine the following scenario. You have a U-shaped tube with a selectively permeable membrane that allows water to pass but not solutes On the left side of the tube you have a 40% NaCl solution and on the right a 15% NaCl solution. The left side of the tube is considered while the right side of the tube is considered ​

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

airlines i think? or a cruise boat? does this work out for u? ?
