check my answer please if it wrong correct me
Osmosis is an ongoing process in the body that is possible because cell membranes are selectively permeable (semipermeable). Osmosis effects can be observed in the lab. For example, differences in osmotic pressure inside and outside a red blood cell can result in crenation (shriveling) or hemolysis (rupture). For this reason, care must be taken when administering intravenous (IV) fluids to hospital patients. If the IV solution has a different concentration from...

5 A cell s a semipermeable membrane through which water may pass. If a cell, having a salinity (salt content) of 1.5% w/v NaCl, is placed in a solution made of normal physiological saline (0.9% w/vNaCl) which way will the water flow? Explain your answer. (Diagrams are OK also, but need to have words explaining it.) Flow of water Bag is a sem permeable Solution in bag "cell" Solution outside of bag (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,...
