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?(1 point)
Responses
A. A platelet has a bigger diameter than a red blood cell by 9.83×10^−6 m.
B. A platelet has a bigger diameter than a red blood cell by 5.17×10^−6 m.
C. A red blood cell has a bigger diameter than a platelet by 5.17×10^−6 m.
D. 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, we compare the diameters of the platelet and red blood cell.
The diameter of a platelet is given as 2.33x10^-6 m.
The diameter of a red blood cell is given as 0.0000075 m.
To compare the two, we subtract the diameter of a platelet from the diameter of a red blood cell:
0.0000075 m - 2.33x10^-6 m
= 7.5x10^-6 m - 2.33x10^-6 m
= 5.17x10^-6 m.
Therefore, a red blood cell has a bigger diameter than a platelet by 5.17x10^-6 m.
The correct answer is:
C. A red blood cell has a bigger diameter than a platelet by 5.17x10^-6 m.
