2. Create a timeline of the history of the microscope and the cell theory. Explain what each of the scientists contributed and put them in order from early to recent dates. Include the dates and summarize their contributions. 3. Zacharias Jensen 4. Antonie Van Leeuwenhoek 5. Robert Hooke 6. Robert Brown 7. Schleiden 8. Schwann 9. Virchow 10. Remak 11.

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
