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 platelet has a bigger diameter than a red blood cell by 5.17×10−6 m.
A platelet has a bigger diameter than a red blood cell by 5.17 times 10 superscript negative 6 baseline m.
A red blood cell has a bigger diameter than a platelet by 5.17×10−6 m.
A red blood cell has a bigger diameter than a platelet by 5.17 times 10 superscript negative 6 baseline m.
A platelet has a bigger diameter than a red blood cell by 9.83×10−6 m.
A platelet has a bigger diameter than a red blood cell by 9.83 times 10 superscript negative 6 baseline m.
A red blood cell has a bigger diameter than a platelet by 9.83×10^−6 m.
A red blood cell has a bigger diameter than a platelet 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 can compare the diameters of a platelet and a red blood cell.
The information given in the question states that a platelet has a diameter of approximately 2.33×10^−6 m, and a red blood cell has a diameter of approximately 0.0000075 m.
Comparing the two values, we can see that the diameter of a red blood cell is larger than the diameter of a platelet.
To find the difference in diameter, we subtract the diameter of a platelet from the diameter of a red blood cell:
0.0000075 m - 2.33×10^−6 m = 0.0000075 m - 0.00000233 m = 0.00000517 m
Therefore, a platelet has a smaller diameter than a red blood cell by approximately 5.17×10^−6 m.
So the correct answer is: A red blood cell has a bigger diameter than a platelet by 5.17×10^−6 m.
