11. What is the largest zoom on the objective lens using our compound microscopes in class? 40x

12. If the power of the objective lens is 40 times, and the power of the ocular lens is 10x, what is the power of the microscope? 400x

13. What are the stages during mitosis and which one takes the longest time? Explain your reasoning. Prophase, Metaphase, Anaphase, Telephase, Cytokinesis Prophase takes the longest time because it has two phases – more happens during prophase than any other phase of mitosis
