Procedure Go to this website and follow these steps Procedure: Go to this website and follow these steps. http://www.glencoe.com/sites/common_assets/science/virtual_labs/LS03/LS03.html 1. Select one of the three cells pictures at the top of the screen and drag it into one of the beakers. 2. Observe the process of osmosis. Determine whether water represented by animated blue arrows, moves into, stays in equilibrium, or moves out of the cell. Observe what happens to the shape and size of the cell. 3. Record your observations in the table below. 4. Move the cell to a different beaker or choose a different cell. Observe the process of osmosis again and record your observations in the table. 5. Repeat this activity with all three cells and all three solutions. 6. Answer the 5 conclusion questions below Complete the table (9 marks) Red Blood Cell: Net Molecule water Moveme nt In/Out Hypotoni c Isotonic Hypertoni Red Blood Cell: Appearanc e of Cell Parameciu Elodea: Elodea: m: Net Net water Appearanc water Moveme e of Cell Movement nt In /Out In /Out Parameciu m: Appearance of Cell c Answer the questions: 1. Did water move into the cell or out of the cell while it was surrounded by hypotonic solution? Explain your answer. 2. In which direction did the water move through the cell membrane when the cell was surrounded by the hypertonic solution? Explain your answer 3. Could Elodea or Paramecium from a freshwater lake be expected to survive if transplanted into the ocean? Explain your answer. 4. For a science perspective is it better to put salt on a meat dish before or after you cook it? Provide an explanation for your answer. Hint use osmosis. 5. Have you ever noticed that salad looks soggy if you add dressing and then leave it in the refrigerator overnight? Explain why this happens in terms of osmosis.

Part 1 Primary Task Response Your first task is to post your own Key Assignment Outline to the discussion area so that other students are able to review your plan. Attach your document to the main discussion post, and include any notes that you feel are appropriate. The purpose of this assignment is to help improve the quality of the Key Assignment Draft that you will complete next week. Respond to Another Student: Review at least 1 other student’s Key Assignment Outline, and provide meaningful feedback. Refrain from general feedback, such as simply stating “good job.” Your feedback to other students is most helpful if you not only point out weak areas but also offer suggestions for improvement. The best feedback takes a three-stage approach to identify what was done well, weaknesses, and areas for improvement. Part 2 Primary Task Response: Within the Discussion Board area, write 400-600 words that respond to the following questions with your thoughts, ideas, and comments. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas. In this Phase, you will be learning about the concept of the cost of capital, how it is calculated, and why it is essential to be used properly. This concept, along with the time value of money concept, will be employed in addressing the Phase 5 tasks and is related to the tasks that you completed in Phase 1 and 3. Identify and recommend at least 1 credible Web site that discusses the process of calculating the cost of capital and it components, and address at least 3 of the following topics: What is the cost of capital, and what role does it play in long-term investment decisions? What are the 3 basic components of the formula, and how is each estimated? Why is the after-tax cost of debt used, and how does this adjustment affect the overall cost of capital? Which component is generally the most expensive, and why? How is the cost of capital calculated, and how are the weights of each component determined? Why is the cost of retained earnings less costly than issuing new equity? What is the difference between the weighted average cost of capital (WACC) and the weighted marginal cost of capital (WMCC), and when should the WMCC be used? Be sure to document your posts with in-text citations, credible sources, and properly listed references.

Which forms are directly useful to plants, and from where do these come? NH4+ and NO3- from ammonification to form ammonium cations and nitrification to form nitrate anions N2 and organic nitrogen (nitrogen bound to carbon-based molecules) from denitrification to form molecular nitrogen and biosynthesis to form organic nitrogen NO2- from nitrification to form nitrite anions Nitrogen containing proteins released from dead organisms by decomposers   14.

HSM 320 WEEK 3 Discussions 1 How has the physician-patient relationship changed over the past century? Are the changes good or bad for the delivery of quality healthcare? Discussion 2 Following Mrs. Cary- admission to the hospital, she has initiated a lawsuit against Family Practice Medical Group (FPMG) and Community Hospital. Her suit claims that Dr. Smith failed to properly supervise his employees and as a result, she received the wrong medication which caused her hospitalization for hypotension (low blood pressure) and delayed treatment for her infection which then became life-threatening. She is also suing Community Hospital because the office staff members are hospital employees. In the lawsuit, is there likely to be a judgment against the hospital? Or FPMG? Why?
