Many old time folk remedies made use of the priciples of diffusion and osmosis. Suppose you had a sliver of wood or another small foreign object embedded under your skin. It is slightly swollen and hurts. Your grandma or older neighbor tells you to soak the affected part in salt water. Using your knowledge of diffusion/osmosis, how do you think this would affect the injury? Will it help you get the sliver out?

Which answer is correct (a or b) for the question about why your hands and feet get wrinkled after staying in the bath for too long. a) the water and dissolved particles are drawn out of your skin by diffusion into the large body of water around you. b) the water is actually drawn into your skin by osmosis. explain why (a or b) is correct.
Using what you know about osmosis, explain how drinking too much water can lead to the deadly condition known as hypernatremia. What effect does this have on the body cells? When survivors are lost at sea, they are told not to drink the ocean salt water. Using what you know about osmosis, explain why drinking too much salt water can also be deadly. What effect would this have on the body cells?
The diagram below represents the process of diffusion through the cell membrane.Identify the condition of the membrane as permeable, semipermeable ornonpermeable. Explain how the condition of the cell membrane affects the process ofdiffusion. Remember to include the concentration gradient.
Some drugs are administered by applying them to the skin (e.g., anicotine skin patch to help a person stop smoking). The drug diffusesthrough the epidermis to blood vessels in the dermis. What kind ofsubstances can pass easily through the skin by diffusion? What kinds ofsubstances have difficulty diffusing through the skin?
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.
Active transport must function continuously because_______. a. plasma membranes wear out b. cells must be in constant motion c. facilitated transport opposes active transport d. diffusion is constantly moving the solutes in the other direction
The principal force driving movement in diffusion is______. a. temperature b. particle size c. concentration gradient d. membrane surface area
Figure 3.22 A doctor injects a patient with what he thinks is isotonic saline solution. The patient dies, and autopsy reveals that many red blood cells have been destroyed. Do you think the solution the doctor injected was really isotonic?
The greater the concentration gradient the slower the rate of diffusion.
What among the following describes osmosis 1. The diffusion of water from an area low solute concentration to an area of high solute concentration. 2. Osmotic pressure is the force that allows water to move by osmosis through a selectively permeable membrane 3. When a cell is immersed in a hypertonic solution, water enters the cell by osmosis which causes it to swell and eventually burst. 4. A solution with greater concentration of water and low concentratioj of solute isbtermed as hyposmotic
Explain the major difference between diffusion and osmosis. Include in your answer which type of the molecule is moving for each process, in which direction the molecules in question are moving (low to high or high to low concentrations).
A student wanted to observe the effect of temperature on diffusion rate. The student set up two glasses of water, one at 35 degrees Celsius and another at 20 degrees Celsius and placed a drop of red dye in each. In which glass of water, would the drop of dye diffuse the fastest? Explain.
