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?
A platelet has a bigger diameter than a red blood cell by 5.17×10^-6 m.
A red blood cell has a bigger diameter than a platelet by 5.17×10^-6 m.
A platelet has a bigger diameter than a red blood cell by 9.83×10^-6 m.
A red blood cell has a bigger diameter than a platelet by 9.83×10^-6 m.
A platelet has a bigger diameter than a red blood cell by 9.83×10^-6 m.
A red blood cell has a bigger diameter than a platelet by 9.83×10^-6 m.
To determine which blood component has a bigger diameter and by how much, we compare the diameters of the platelet and red blood cell.
The diameter of a platelet is given as 2.33×10^-6 m, and the diameter of a red blood cell is given as 0.0000075 m.
To find the difference in diameter, we subtract the diameter of the platelet from the diameter of the red blood cell:
0.0000075 m - 2.33×10^-6 m = 0.0000075 m - 0.00000233 m ≈ 0.00000517 m
So, the difference in diameter between a platelet and a red blood cell is approximately 5.17×10^-6 m.
Therefore, the correct answer is: A platelet has a bigger diameter than a red blood cell by 5.17×10^-6 m.
