Platelets and red blood cells are components of the blood. A typical platelet and red blood cell have diameters of approximately 2.33×10^-6 m and 0.0000075 m, respectively. Which blood component has a bigger diameter, and approximately by how much?

Answer 1

To determine which blood component has a bigger diameter, we need to compare the diameters of the platelet and the red blood cell.

The diameter of a platelet is approximately 2.33×10^-6 m.
The diameter of a red blood cell is approximately 0.0000075 m.

To compare these diameters, we can subtract the diameter of the platelet from the diameter of the red blood cell:

0.0000075 m - 2.33×10^-6 m = 0.00000517 m

Therefore, the red blood cell has a bigger diameter by approximately 0.00000517 m.
