Lab Quiz #4 Diffusion and Osmosis A+ RATED

Lab Quiz #4 Diffusion and Osmosis What is the process that involves the movement of water molecules, through a membrane, to the higher solute concentration called? - correct answers Osmosis What is the process that involves the movement of water molecules called? - correct answers Osmosis What is the process that involves the movement of other kinds of molecules called? - correct answers Diffusion In some places, heavily salted hams are hung in the open in stores. They may be left uncovered for months without rotting. Based on your knowledge of osmosis and diffusion, which of the following is most likely to explain the death of the bacteria that land on the ham surface? - correct answers The salt causes water to move out of the bacteria cells What is the movement of molecules from an area of higher concentration to an area of lower concentration called? - correct answers Diffusion How does temperature affect the rate of diffusion? - correct answers As temperature increases, rate of diffusion increases What is the process of water going to a higher solute concentration called? - correct answers Osmosis What is the process of going from a high to low concentration called? - correct answers Diffusion What does it mean to have the same concentration? - correct answers Isotonic What does it mean to have a lesser solute concentration? - correct answers Hypotonic What does it mean to have a higher solute concentration? - correct answers Hypertonic Dialysis tubing is filled with a 10% sugar solution and put in a beaker of 20% sugar solution. What is the solution? Which way will the water go? - correct answers Hypertonic and into the beaker A hypothetical plant cell has a 5% starch concentration. It is put into a beaker of distilled water (0% starch). What is the solution? Which way will the water go? What will happen to the plant cell? - correct answers Hypotonic, into the tubing, turgid A red blood cell with 0.9% salt is put into a beaker of 15% salt. What is the solution? Which way will the water go? What will happen to the red blood cell? - correct answers Hypertonic, into the beaker, hemolysis Dialysis tubing is filled with a solution of unknown concentration. It is put in a beaker with of 25% starch. Water is slowly moving into the bag. What is the solution? What is the concentration of starch in the tubing? - correct answers Hypotonic and greater than 25%
