7. Which statement is correct? (1) The coarse adjustment should be used to focus on high power. (2) When using the microscope, first find the specimen on high power, center the specimen in the field of view and then focus and view the specimen on low power. (3) As we go from low to high power, the field of view gets smaller and the image gets darker. (4) The total magnification of the microscope is computed by multiplying the objective powers together
8. The technique of lowering the coverslip at an angle is used to (1) make organelles more visible (2) reduce the formation of air bubbles (3) make the specimen transparent (4) reduce the size of
