platelets and red blood cells are components of the blood a typical platelet and red blood cells have diameters of approximately 2.33 * 10 ^ -6 m and 0.0000075 m. which blood component has a bigger diameter and approximately by how much?
A. a red blood cell has a bigger diameter than a platelet by 9. 83 * 10 ^ - 6 m
B. The platelet has a bigger diameter than a red blood cell by 9.83 * 10 ^ -6 m
C. A red blood cell has a bigger diameter than a platelet by 5.17 * 10 ^ -6 m
D. The platelet has a bigger diameter than a red blood cell by 5.17 * 10 ^ -6m
The correct answer is C. A red blood cell has a bigger diameter than a platelet by 5.17 * 10 ^ -6 m.
To determine this, subtract the diameter of the platelet from the diameter of the red blood cell:
0.0000075 m - 2.33 * 10 ^ -6 m = 5.17 * 10 ^ -6 m
To determine which blood component has a bigger diameter and approximately by how much, we can compare the diameters of the platelet and red blood cell.
The diameter of a platelet is given as 2.33 * 10^-6 m.
The diameter of a red blood cell is given as 0.0000075 m.
Comparing these values, we can see that the red blood cell has a bigger diameter.
To find the difference between the diameters, 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
Approximately, this difference is equal to 5.17 * 10^-6 m.
Therefore, the answer is:
C. A red blood cell has a bigger diameter than a platelet by 5.17 * 10^-6 m.
To determine which blood component has a bigger diameter and by approximately how much, we need to compare the sizes of a platelet and a red blood cell.
According to the information given, a typical platelet has a diameter of approximately 2.33 * 10^-6 m (or 0.00000233 m) and a red blood cell has a diameter of approximately 0.0000075 m.
To find the difference in diameter, we subtract the diameter of a platelet from the diameter of a red blood cell:
0.0000075 m - 0.00000233 m = 0.00000517 m
Therefore, the difference in diameter is approximately 5.17 * 10^-6 m.
From the options provided:
A. A red blood cell has a bigger diameter than a platelet by 9.83 * 10^-6 m (incorrect, as the correct answer is smaller)
B. The platelet has a bigger diameter than a red blood cell by 9.83 * 10^-6 m (incorrect, as the correct answer is smaller)
C. A red blood cell has a bigger diameter than a platelet by 5.17 * 10^-6 m (correct)
D. The platelet has a bigger diameter than a red blood cell by 5.17 * 10^-6 m (incorrect)
Therefore, the correct answer is C. A red blood cell has a bigger diameter than a platelet by 5.17 * 10^-6 m.
