Review the following experiment and answer thequestions.You set up an experiment where you place a sealed(clamped) dialysis tube cell in a beaker of water. Thesolution in the dialysis tube cell is 25%NaCl solution andthe solution in the beaker is 1%NaCl solution. The solventfor both is water.Before you place the tube in the cell, after it has been filledand clamped, you find the mass of the cell. You also findthe mass of the cell after it has been placed in the beakersolution for 30 minutes. The masses are in the table below.Mass in grams of dialysis tube cellInitial Mass25gFinal Mass after 30 minutes 28.7gUsing this information, explain the difference in massbefore and after submerging the cell in the beaker solution.Explain.

2. Circle the correct bolded blue word. a. A substance that moves across a membrane "down" or "with" their concentration gradient is moving from the side with a higher / lower concentration of that substance to the side with a higher / lower concentration. This does / doesn't require energy input and is called active / passive transport. b. A substance moving "against" or "up" its concentration gradient is moving from the side with a higher / lower concentration of that substance to the side with a higher / lower concentration. This does / doesn't require energy input and is called active / passive transport. c. If the energy from the hydrolysis of ATP is directly used to pump the substance, the transport is called primary /secondary active transport. d. Ion-coupled transport is primary /secondary active transport and has two parts. First, the hydrolysis of ATP is used to power the creation of an ion concentration gradient. The ion is typically Na* or H*. Second, the energy stored in…
