microscopic organism. The eyepiece of the microscope has a
magnification of 20x, and the objective lens being used has a
magnification of 40x. The student draws a detailed diagram of a cell they
observed. Later, they measure the cell's size in their drawing and find it
to be 20 millimeters (mm) in length. What is the actual size of the cell in
micrometers (μm)?
A 0,025
B 0,25
C 2,5
