- Using the appropriate osmotic terms (hypertonic, hypotonic, or isotonic) describe what would happen to each organism in the following settings: a. A bunch of carrots are placed soaked a sink of distilled water.For your first experiment you make a membrane of pure myristic acid and measure the melting curve (shown below). Label the position on the plot that indicates the melting temperature (Tm). In the space below describe the physical basis for the observed temperature response of the membrane. Also draw the melting curve for stearic acid membrane Membrane Fluidity TemperatureSuppose your instructor sent you an image of human epithelial cells, and he indicated the magnification to equal 1300 X. What would be the cell's actual size under high power, knowing that the cell measured ten subdivisions of the microscope graticule? Pleaseindicate the unit beside the number. Answer: In the process of isolating the enzyme amylase, you used methanol: O a. To precipitate the polar enzyme O b. To dissolve the starch O C. To dissolve the sugar O d.

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.
