Platelets and red blood cells are components of the blood. A typical platelet and red blood cell have diameters of approximately 2.33 × 10^-6m and 0.0000075m respectively. Which blood component has a bigger diameter and approximately by how much?
1. A platelet has a bigger diameter than a red blood cell by 5.17 × 10^-6m
2. A red blood cell has a bigger diameter than a platelet by 5.17 × 10^-6m
3. A red blood cell has a bigger diameter than a platelet by 9.83 × 10^-6m
4. A platelet has a bigger diameter than a red blood cell by 9.83 × 10^-6m
The correct answer is:
2. A red blood cell has a bigger diameter than a platelet by 5.17 × 10^-6m
