Homework H4: Microscope Review and Basic Chemistry and pH 1. Looking at the following coll, identify and give functions for al the organelles labeled here. 2. Is this cell a eskaryolic or prokaryotic cell? 3. Is this cell an autotrooh or a hetergtroph? What doos that mean that this cell can do? 4. After calibrating the ocular ruler with a stage micrometer, it has been determined that 10 reticula units corresponds to $0.025\mathrm{mm}$. Use a ratio to determine the size of the cell. What is the diameter of Cell \#1? um What is the diameter of Cell \#2? Which of these cells is a prokaryotic cell? Why do you say so? $\mathrm{mm}$ or $\mathrm{mm}$ or $\mu \mathrm{m}$ Biological Chemistry and Biological Molecules After you have finished reading the Biological Chemistry and Biological Molecules soction of your lab syllabus, answer the following questions: 16. What types of solutions help to keep it in this range (general name, not specific molecules). 17. What $\%$ of the adult human body weight is made up of protein? 18. What percentage is made up of nucleic acids? 19. What percontage is carbohydrate? 20. About $15-20\%$ of the adult human body weight is fat. If a person is of normal weight, they could have a body fat content of about $18\%$. If so what is their body water \% (add up the above and subtract from 100\%) If they were somewhat overweight, they could have a content of $24\%$. What would their $\%$ body water be? 21. If one were to increase the number of hydrogen ions in a solution with a $\mathrm{pH}$ of 3 by 10 times, what would the $\mathrm{pH}$ of the new solution be? 22. Define electrolyte and give an example of one found in the body. Do any tissues or cells in the body conduct electrical currents? Why? 2 10. Draw two molecules of water and then draw and label the type of bond that holds one molecule to the other. (This one will take some care-) 11. What is the name of this molecule? 12. This molecule is a subunit of what larger type of molecule found in the body? 13. What does the $\mathrm{pH}$ scale measure? 14. If you had a solution with a pH of 6 and another with a pH of 9, which one would have more hydrogen ions in it? 15. What is the normal $\mathrm{pH}$ range for the plasma of the blood in humans? 1. What is an atom? 2. Give an example of an atom found in the human body (both its common name and the atomic symbol). 3. What is an ion? 4. Give an example of an ion found in the human body (both its common name and its symbol). 5. What are covalent bonds? 6. Give an example of a molecule formed with a covalent bond found in the human body (both its common name and its molecular formula). 7. What type of bond is used to form $\mathrm{NaCl}$ ? 8. How does this type of bond differ from a covalent bond? 9. What type of bond is used to keep a strand of DNA attached to its paired, second
