Two cells are viewed and measured under a microscope. The approximate diameter of each cell is listed. Cell P: 5.0×10^−4 m Cell Q: 3.0×10^−5 m Which expression would you use to find the difference between the two diameters?

To find the difference between the two diameters, you would subtract the diameter of cell Q from the diameter of cell P. So, the expression you would use is:

(5.0×10^−4 m) - (3.0×10^−5 m)
