- Which of the following occurs when erythrocytes are transferred from an isotonic solution to a hypertonic solution? Water leaves the cell and results to crenation. B Water leaves the cell and results to osmotic lysis. C) Water enters the cell and results to crenation. D Water enters the cell and results to plasmolysis.arrow_forwardActive tissues generate carbon dioxide, which diffuses out of the tissue into the bloodstream, to be carried away. Is this diffusion into the blood a case of flow up a gradient, or down? Explain.arrow_forwardOver the course of life, the diffusion capacity decreases by aboutA. 5 percent B. 10 percent C. 15 percent D. 20 percentarrow_forward
- How much time would it take ATP to diffuse the following distances? (Use the equation for mean squared displacement in 1 dimension.) A. 1 µm (roughly the size of a bacterium) B. 6 µm (roughly the diameter of a T cell) C. 1 m (roughly the length of the axon of the sciatic nerve, which extends from the spinal cord to the big toe) D. Besides diffusion, what other mechanisms might a neuron use to transmit signals and transport molecules?arrow_forwardOxygen and carbon dioxide diffuse across our respiratory surface into and out of the blood via simple diffusion. The respiratory membrane is thin so gases diffuse only a short distance through the liquid and into the blood. Fluid buildup in the lungs increases the distance through the liquid medium. How does this impact the concentration of oxygen in the blood? Explain.arrow_forwardThe small capillaries in the lungs are in close contact with the alveoli. A red blood cell takes up oxygen during the 0.5 s that it squeezes through a capillary at the surface of an alveolus. What is the diffusion time for oxygen across the 1-μm -thick membrane separating air from blood? Assume that the diffusion coefficient for oxygen in tissue is 2×10−11m2/s. Give your answer to 1 significant figure.arrow_forward

Select one: a. Diffuse Side A to Side B. b. Diffuse Side B to Side A. c. No diffusion will occur; it is already at equilibrium.arrow_forwardThe direction that a gas diffuses is determined by a. the solubility of the gas in the solutions present on either side of a semipermeable membrane b. the partial pressure of the gas on either side of a semipermeable membrane c. the concentration of solutes in the solution into which the gas is dissolving d. none of the choices is correctarrow_forwardThe rate of diffusion increases if thea. concentration gradient decreases.b. temperature of a solution decreases.c. viscosity of a solution decreases.d. All of these are correct.arrow_forward
- How would a decrease in the concentration of oxygen in the lungs affect the diffusion of oxygen into the blood?arrow_forwardunder what circumstances does diffusion and bulk flow work most efficiently?arrow_forwardThe following are the factors that affect rate of diffusion across respiratory membrane: a. Membrane thickness. b. Molecular weight and solubility of the gas. c. All of the above correct. d. Surface area. e. Partial pressure difference across respiratory membrane.arrow_forward
