- Everybody Wrk UL6- Sca woy coutt an N pack filled with pure water potentially kill a patient? INDEPENDENT PRACTICE The diagrams below represent animal and plant cells in beakers containing solutions of vanina levels, The level of dissolved salts in each solution is indicated in the diagram. Assume each celt a salt concentration of 0.8% Analyze each diagram and complete the following: Line A- indicate whether the solution is hypertonic, hypotonic or isotonic relative to the cel Line B- indicate the direction of water movement: into the cell, out of the cell, in and out equally Line C- describe any changes that would take place in the cell (ex: the cell would... swell. shrivel, burst, etc.) O= Animal Cell = Plant Cell A. 1.

Bag 1: Bag 2: Bag 3: (c) Explain why the volume of each bag changed during the experiment.Scientists let rice blast fungal infection cells attach to and attempt to penetrate six different polymer sheets for different lengths of time and in varying extracellular osmotic pressures (Figure 22.9). As the number of the sheet increases so does its hardness. Which of the following makes the most sense based on the data? 100- 60 40- 20- 192 incubation time (hr) 72 96 240 100- 80- 60- 40- 20- b-Oo 8 10 12 extracellular osmotic pressure, MPa Figure 22.9 Penetration as a function of incubation time (A) and extracellular osmotic pressure (B). Numbers 1 to 6 in both panels indicate the substrate, with lower numbers being softer substrates. Percent penetration goes down over time and as substrate hardness increases. If penetration of a substrate occurs at a particular external pressure, this indicates that internal pressure is high enough to allow penetration of the particular substrate. Harder substrates are more easily penetrated when extracellular osmotic pressures are low. The…
- The left beaker contains 9mM NaCl and 9mM glucose solution.The right beaker contains distilled water.The molecular weight of NaCl is 58.44 g/mol. The molecular weight of glucose is 180.16 g/mol. The membrane located between the two beakers is impermeable to NaCl and glucose. The membrane is permeable to H2O. What will occur across the membrane?In the dialysis bag experiment, what do you think will happen if we reverse the two solutions between the sac and the beaker for sac 4 (meaning sac 4 is filled with distilled water and beaker 4 is 40% sucrose)? Will the sac gain or lose weight? a water will not move because sac membrane is impermeable to sucrose; the sac will have no change in weight b water will not move because sucrose can move across the sac membrane to equilibrium; the sac will have no change in weight c water will move out of the sac; the sac lose weight d water will move into the sac even more; the sac will gain weightYou are developing a porous membrane for use in a dialysis system. The membrane must be able to retain both protein and glucose on the inlet side and allow other, smaller molecules to flow through. You have found that the membrane is 0.25 mm thick and contains long, rectangular pores with a width of 0.1 microns. 57% of the 50 cm^2 membrane surface area is covered with pores. A test fluid (viscosity = 1.5 cP, density = 1015 kg/m^3) is passed through the membrane. You can assume that the test fluid has a composition similar to that of blood plasma. An initial test is run at physiological conditions, and you observe that the flow rate of fluid through the membrane is 500 cm^3/min. _Given this data, what must the hydrodynamic pressure drop across the membrane in your test system be in pascals?

- 6. As a demonstration, an artificial cell consisting of an aqueous solution enclosed in a semi permeable membrane is placed into a beaker containing a different solution. The membrane is permeable to water and to monosaccharide's glucose and fructose but completely impermeable to the disaccharide sucrose.

Explain. b. Which solute(s) will exhibit a net diffusion out of the cell? Explain. C. Which solution is hypertonic, the cell or the solution? Explain.determine if osmosis or simple diffusion A crystal of blue copper sulfate is placed in a test tube of water. The next day, the solid is gone, but the water is evenly colored. A fresh potato is peeled, weighed, and soaked in a strong salt solution. The next day, it is discovered that the potato has lost a significant amount of mass. A perfume bottle is opened, and soon the odor can be sensed in all parts of the room. Garden grass wilts after being exposed to dry chemical fertilizer. Plant seeds soaked in water swell and become several times as large as before soaking. A sugar cube is dropped into a cup of hot water, and without being stirred, all of the liquid becomes sweet tasting.حالة إكمال الأسئلة يقوم الانتقال إلى سؤال آخر بحفظ هذا الرد. السؤال 3 ?What happens when a round cell expands in diameter Its surface area and diameter increase with the cube of its diameter .1 O Its surface area and diameter increase with the square of its diameter .2 Its volume increases faster than its surface area does .3 O Its surface area increases faster than its volume does .4 Its volume and surface area expand with the same proportion 5 يقوم الانتقال إلى سؤال آخر بحفظ هذا الرد.
