RNDr. Josef Reischig, CSc.]What explains the appearance of the cell in the micrograph?A. The cell is dying.B. The DNA is replicating.C. The cell is in metaphase.D. The cell is in telophase.

A scientist observed a skin cell using an electron microscope.The size of the image was 25 mm, and the magnification was × 100,000.Calculate the real size of the cell, giving your answer in nm.

The diameter of a field of view is 4.7mm. 4 cells fit across the diameter under 4x objective magnification.What is the actual size of each cell?2019 Atomi QuestionA(Choice A)2.94μmB(Choice B)29.4μmC(Choice C)0.0294μmD(Choice D)0.294μm

Magnification can be calculated using the equation: magnification = size of image / actual size of the specimen. A bacterial cell is 0.003mm long. A magnified image of the cell is 21mm long. The magnification of the image is ×_____.
