DO NOT COPY THE ANSWER FROM THE SAME QUESTION. Sassa, a biology professor, wanted to demonstrate to her students the applicability of a dialyzing membrane (DM) as a model for the cell membrane by enclosing an aqueous solution in a DM bag and immersing in a beaker containing a different solution. Substances available which are permeable to the DM include 0.02 M NaCl, 0.03 M glucose, and 0.01 M glucose. The only substance available which is completely impermeable to the DM is the 0.01 M lactose. Using the substances given and materials such as a beaker, stirring rod, and string, draw ONLY ONE set-up that can be demonstrated by Ms. Sassa that will satisfy ALL of the following conditions:a. No solute will exhibit a net diffusion out of the cell.b. Glucose will exhibit a net diffusion into the cell.c. NaCl will exhibit a zero net d. No net movement of lactose from the inside to outside of the cell. Make sure to label properly the substance inside the beaker and inside the DM bag.
. DRAW IT An artificial “cell” consisting of an aqueous solutionenclosed in a selectively permeable membrane is immersed ina beaker containing a different solution, the “environment,”as shown in the accompanying diagram. The membrane ispermeable to water and to the simple sugars glucose and fructosebut impermeable to the disaccharide sucrose.(a) Draw solid arrows to indicate the net movement of solutesinto and/or out of the cell.(b) Is the solution outside the cell isotonic, hypotonic, orhypertonic?(c) Draw a dashed arrow to show the net osmosis, if any. (d) Will the artificial cell becomemore flaccid,more turgid,or stay the same?(e) Eventually, willthe two solutionshave the same ordifferent soluteconcentrations?

Match the following statement related to membrane transport processes to the appropriate term or terms: passive transport, facilitated transport, active transport. A transporter (or carrier) protein is necessary. (Select all that apply.) passive transport facilitated transport active transport O O
The average concentration of salt in seawater is about 3.5 percent and the average concen- tration of salt in the human cellular environment is about 0.9 percent. Drinking seawater can be fatally harmful and is highly discouraged even in the most severe cases of dehydration. Which of the following provides the most likely cause for this fact? A B с D The increase in salt concentration in the extracellular environment will increase the per- meability of the cell membrane. The increase in salt concentration in the extracellular environment will cause the move- ment of water into the cell. The increase in salt concentration in the extracellular environment will cause the move- ment of water out of the cell. The increase in salt concentration in the extracellular environment will decrease the per- meability of the cell membrane.

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).

Melvin, ace biology student, is making a display for Ms. Fishhawk's class to show what "isotonic," "hypertonic" and "hypotonic" mean. Melvin has a tank where the two sides are separated by a semi-permeable membrane. The figure shows the solutions that Melvin pours into each side of the tank. 30% starch 70% water A 5% starch 95% water B a. Label the figure to show which side is the hypertonic side and which is the hypotonic side.
