Use the following diagrams To answer questions A-E: 0 min20 min A B A BProteinA) Why did the amount of water change? Equillibrium needed to be establishedB) Why did the amount of protein stay the same? Protein is too large to pass through the cell membrane.C) If the 0 min diagram concentration of protein on side A was 12% and side B was 4%. What would the concentration be in the 20 min diagram on side A 8% , side B_ 8% D) At equilibrium water molecules continue to move between the two sides. However the number entering side A is equal to than/to the number entering side BE) In the diagram give one example of: ( Be Specific) a) isotonic Side A vs. B in the 20 min diagram b) hypotonic: Side B compared to A in the 0 min diagram c) hypertonic: Side A compared to B in the 0 min diagram8. Given : Solution A: 100 mL waterSolution C: 90 mL water & 10g saltSolution B: 95mL water & 5 g saltSolution D: 45 mL water & 5 g salt* note 1mL of water = 1 gFill in the blank with one of the following words: Hypertonic, Hypotonic or IsotonicSolution A is _ Hypotonic _compared to solution BSolution C is _ Hypertonic _compared to solution BSolution D is _Hypertonic _compared to solution ASolution D is _Isotonic _compared to solution CSolution B is Hypotonic compared to solution C9. Use the following information for the next question: * Note: Too much salt is toxic to cellsBeaker ABeaker BBeaker CBeaker D% Salt Solution in cells1%1%0.1%0.1%% Salt Solution in water surrounding cells1%0.1%1%0.1%Which of the above illustrates active transport? _Beaker C Explain: The cell is using energy to minimize the amount of salt that is internalized10. Why does grass wilt if it is over fertilized? Outside solution is hypertonic with a lot of fertilizer minerals. Water water is pulled by osmosis from where the water concentration is higher ( Inside the plant cells) to where the water concentration is lower (in the surrounding soil) 11. A marathon runner collapses after running on a hot day. Although the runner consumed water along the route, analysis shows that many of the runner’s red blood cells burst. Explain. ( Hint: along the route only pure water was available) With only pure water taken in ( no salts) the solution outside of the red blood cells is hypotonic. Water travels from the hypotonic solution (high water- outside) to the hypertonic solution ( low water- inside). The rush of water causes cell bursting.The following web sites have good review practice for cells and cell transport.Biology a guide to the online world*Chapter 4 Cells and Chapter 5 The Cell Membrane ( Transport) has a basic quiz and achallenge quiz ( as well as links)Online Biology Book*Chapter 5 (Cells) and Chapter 6( Transport) has readings and great diagrams of the organelles in the cell as well as some review questions and links. Also has readings and diagrams of types of transport and the cell membrane.Gresham High School IB Biology Web Site*Section on Cells – Notes ( has good notes, diagrams and links on both cells and on transport through cells)*Section on Cells- Reviews ( has practice multiple choice questions)Mr. Jenzen’s Biology Home Page 4 and 5 ( good links for extra readings / info on cells and transport) ................
