1. What is the formula for Total Magnification?
Answer: Total Magnification = Ocular (10x) * Objective (4x, 10x, 40x). Example 10 * 40 = 400x.
2. What objective lens is the only one where you should use the fine focus
knob?
Answer: The 40x objective.
3. What is the correct order of the phases of mitosis?
Answer: Prophase -> Metaphase -> Anaphase
-> Telophase (followed by Cytokinesis).
4. Calculation You count 100 cells and 72 are in interphase. How many hours
does interphase take in a 24-hour cycle?
, Answer: (72/100) * 24 = 17.28 hours.
