- 3. Draw and label a diagram that demonstrates the difference between tonicity and osmolarity. Be sure to label the new solutions in each condition, draw the changes (if predicted) in cell shape/volume, and clearly use arrows to indicate the movement of water relative to the cell. Please start with a red blood cell in an isotonic solution (Figure D) and show what happens to cell shape and water movement when NaCl (remember that the membrane is permeable to neither of these ions) (Figure E) or urea (a permeable ion) (Figure F).What condition does the diagram show? movement of water a) The solution on the left side of membrane is hypoosmotic. b) The solution on the left side of the membrane is hyperosmotic. c) The solution on the left side of the membrane is isoosmotic. O d) The solution on the right side is hyperosmoticWhat is meant by concentration gradient? Is it correct to refer to “concentration gradient of water”?
- What is the difference between a hyperosmotic solution and a hypertonic solution?5) What term is used to describe when two solutions have reached a balanced state?IsotonicHypertonicHypotonicTonicity 6) Blood is what kind of solution? Isotonic Hypotonic Hypertonic None of the aboveDefine osmosis, and describe how osmotic pressure iscreated. As the concentration of a solution increases, whathappens to its osmotic pressure and to the tendency forwater to move into the solution?
- Consider the two solutions separated by an ideal semipermeable membrane (permeable to water but impermeable to solute). Assuming complete dissociation of all the salts you can expect: a.) net water movement from side 1 to side 2 b.) net water movement from side 2 to side 1 c.) no net water movement8. When solutes move across a semipermeable barrier from areas of high concentration to low concentration: it requires energy input. it requires no net energy input. it causes the water to go up. the total solute concentration increases.Water molecules tend to diffuse in response to their own concentration gradient. How can water be more or less concentrated?
- Osmolality E Volume 46. The solid lines on the diagram indicate normal volumes and osmolalities of intracellular (1) and extracellular (E) fluid. The changes represented by the broken lines are most likely caused by A) cholera B) diabetes insipidus C) hypersecretion of ADH (vasopressin) D) hypoaldosteronism E) isotonic volume expansionRed blood cells with an internal osmolarity of 300 mOsM/L are placed in a solution containing 300mOsm/L glucose. Which of the following must be TRUE about the solution? a) the solution is isosmotic b) the solution is isotonic c) both A and B d) Neither A nor BPlease answer.... a) State which series depcit tubes that were placed in isotonic, hypertonic, and hypotonic environments. b) In the above graph, which tubes appear to show internal turgor pressure counteracting osmosis? Explain how you can tell this by looking at the graph.
