What part of the microscope adjusts the magnification of the microscope? Group of answer choices A. objective lens B. on/off switch C. iris D. course adjustment

4. If the diameter of the field of view (FOV) for your microscope is 5.5 mm at 40x total magnification, what is the diameter of the FOV at 1000X? Show work and don't forget units! 5. Use the counting method to estimate the length of an elodea cell. You will need to use your calculation for the FOV at 400x total magnification. Show work and don't forget units! Elodea Leaf at 400x total mag 6. Use the percent method to estimate the size of a human cheek epithelial cell. You will need to use your calculation for the FOV at 1000x total magnification. Show work and don't forget units! Cell Membrane Nucle us

In light microscopy, when magnification is increased, the lens focuses closer to the sample.  This makes the user more likely to ram the sample into the lens.  Why is it common for the lens to focus closer to the sample at higher magnifications? What can be done to mitigate this risk?
