Help me get the correct answers for the pictures and the
question at the bottom.
Cell membranes are semipermeable, and osmosis is an ongoing process in the body. Differences in osmotic pressure inside and outside a red blood cell can result in crenation (shriveling) or hemolysis (rupture). The diagram shows three solutions: an isotonic solution, a hypertonic solution, and a hypotonic solution. Place the appropriate red blood cell in each solution. isotonic solution hypertonic solution hypotonic solution Answer Bank The...

74 Percent Concentration -The amount of solute dissolved in a fixed amount of solvent is called the concentration of the solution. Concentrations are typically expressed as Mass al.) (% m/m) which is the mass of the solute (g) divided by the mass of the solution [solute+ solvent] (g)x 1000/0; or as Volume ol.) (% v/v ) which is the volume of the solute in a fixed volume of solution (1O0mL of solution) x 1000/0; or less commonly in the laboratory,...

a. Consider these two solutions: Solution A is prepared by dissolving 5.00 g of MgCl2 in enough water to make .250 L of solutions, and Solution B is prepared by dissolving 5.00 g of KCl in enough water to make .250 L of solution. Which direction will solvent initally flow if these two solutions are seperated by a semipermeable membrane? b. Assuming that the volumes of the solutions described in question 4 are additive and igoring any effects that gravity...
