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 What is the difference in the diameters of the two cells?

To find the difference in diameter between the two cells, we subtract the diameter of cell Q from the diameter of cell P:

5.0×10^−4 m - 3.0×10^−5 m = 4.7×10^−4 m

Therefore, the difference in the diameters of the two cells is approximately 4.7×10^−4 meters.
