A compound microscope has an ocular micrometer calibrated to 12μm for each observable division in its scale. The widest part of an ellipsoidal microorganism observed under 4x magnification spans to the 18th division on the ocular microscope. What is the actual size of the microorganism? 12 μm 18 um 72 μm 180 μm 216 μm

Will the entire organism described in question 3 be observable under the highest power magnification (100x)? Provide a justification for your answer.
OYes, because the field of view diameter at 100x magnification is less than the diameter of the organism
O No, because the field of view diameter at 100x magnification is less than the diameter of the organism
Yes, because the field of view diameter at 100x magnification is greater than the diameter of the organism
O No, because the field of view diameter at 100x magnification is greater than the diameter of the organism
