-t I: Multiple Choices (4 points each) 1. Sheyla knows that cell membranes are semipermeable. The physiological saline is 0.90 % w/v NaCl solution. What happens to erythrocytes (red blood cells) placed in a 0.9 % w/v saline solution? a. The 2.0 % w/v saline solution is hypertonic. Erythrocytes will lose water and shrink. b. The 2.0 % w/v saline solution is hypotonic. Erythrocytes will swell due to entering water. c. The 2.0 % w/v saline solution is isotonic. No...

_____membranes proteins are associated with the bilayer through interactions with other membrane component on the surface of the membrane. Net movement of particles from a region where they are more concentrated to a region where they are law concentrated is called Diffusion of water through a selectively permeable membrane down its own concentration gradient It called A solution with an equivalent concentration of water and hence the tame osmotic pressure as the fluid inside the cell is said to be...

If volume and the amount of gas within a container remains constant, what will happen to the pressure...
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,...
CRITICAL THINKING QUESTIONS 1. A pre-weighed dialysis bag which contained a solution of 10% glucose was placed in a beaker containing a solution of 20% glucose. After one hour, the bag was weighed again a. Calculate the % mass change of this dialysis bag from the following information: • Mass of bag before experiment: 15.39 • Mass of bag after experiment: 12.79 b. Determine the tonicity of the beaker when it is compared to the dialysis bag: 2. facell had...

How many nanoseconds is this 5 x 10-9 s? Express these non-exponentially, and chose the unit and prefix that works best: 2 x 10-3 s; 1.5 x 10-4 l; 4 x 10-8 g If the normal resting cardiac output is around 5 liters per minute, how many ml is that in a second? Express in real numbers and exponentially. The rate of DNA replication is about 2 kb (kilobases) per minute. How many bases is that per second? Dr. Russo...
