Indicate which of the following provides an example of diffusion by answering yes or no. A crystal of blue copper sulfate is placed in a test tube of water. The next day the solid is gone, but the water isevenly colored.___________

If a dialysis tube that is permeable to water but not sucrose contains a 40% sucrose solution that is in a beaker of water, the solution in the beaker is said to be:     cannot be determined     isotonic     hypertonic     hypotonic

For a lab on diffusion and osmosis, where a egg yolk was placed in a cup water the following question asks Consider a scenario in which the size of an egg yolk remains unchanged after in water soaking for an hour. What are two possible explanations as to why this occurs? What would two reasons be for the yolk to be unchanged after a hour in water?

Examine the graph presented here. Using your knowledge of how the processes work, label each curve as representative of either simple diffusion or facilitated diffusion. Explain how you determined which curve was which.

You were introduced to osmosis in Chapter 8 earlier in the course. This week, Chapter 15 continues this discussion by introducing the cell membrane. For additional information, review one or two of the websites listed below. Osmosis: Real-life Applications How Is Osmosis Used in Kidney Dialysis? Guide to Forward Osmosis Applications Choose one way that osmosis and membranes are used in living things, medicine or industry. Describe how osmosis and membranes are used in the real-life application you chose. What are some of the materials necessary? Is an input of energy necessary?

Label the nucleus, cytoplasm, and cell membrane of the following pictures. The red one is the human red blood cell under HPO, while the orange one is the toad red blood cell. Describe each cell and compare the two.

Select the best option: In diffusion, substances move from areas of (greater) (lesser) to (greater) lesser concentrations.

Statement 1: The direction of diffusion of a solute across a membrane is determined by its concentration gradient and always moves toward equilibrium. Statement 2: In passive transport, solutes move down the gradient from a region of low concentration to a region of high concentration. A Both statements are true. Both statements are false. C) Statement 1 is true. Statement 2 is false. Statement 1 is false. Statement 2 is true.

A paramecium cell placed into a hypotonic solution will experience which of the following effects? expulsion of the excess water using its contractile vacuoles plasmolysis hemolysis shrinkage crenation

Cotransport is ____________     movement of water down concentration gradient using a protein channel     movement of materials against their concentration gradient     movement of one substance against, and one substance down their concentration gradients     movement of molecules from high concentration to low concentration using no protein channels     movement of materials down their concentration gradient using a protein channel
