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)
A. a red blood cell has a bigger diameter than a platelet by 9.83 x 10^-6m
B. a platelet has a bigger diameter than a red blood cell by 9.83 x 10^-6m
C. a platelet has a bigger diameter than a red blood cell by 5.17 x 10^-6m
D. a red blood cell has a bigger diameter than a platelet by 5.17 x 10^-6m
To determine which blood component has a bigger diameter, we need to compare the given values:
The diameter of a red blood cell is approximately 2.33 x 10^-6 m.
The diameter of a platelet is approximately 0.0000075 m.
It is clear that the diameter of a platelet (0.0000075 m) is larger than the diameter of a red blood cell (2.33 x 10^-6 m).
So, the correct answer is:
B. a platelet has a bigger diameter than a red blood cell by 9.83 x 10^-6m.
correct!
Thank you! I'm glad I could help. If you have any more questions, feel free to ask!
To determine which blood component has a bigger diameter, we need to compare the diameters of a red blood cell and a platelet.
The diameter of the red blood cell is given as approximately 2.33 × 10^-6 m.
The diameter of the platelet is given as approximately 0.0000075 m.
First, let's convert the diameter of the red blood cell to scientific notation to match the given format:
2.33 × 10^-6 m = 2.33 × 10^-6 m.
Comparing the diameters, we find:
2.33 × 10^-6 m < 0.0000075 m.
This means that the diameter of the platelet is larger than the diameter of the red blood cell.
To find the difference in diameter, we subtract the diameter of the red blood cell from the diameter of the platelet:
0.0000075 m - 2.33 × 10^-6 m = 0.00000517 m.
Thus, the platelet has a bigger diameter than the red blood cell by approximately 5.17 x 10^-6 m.
Therefore, the correct answer is:
D. a red blood cell has a bigger diameter than a platelet by 5.17 x 10^-6 m.
To determine which blood component has a bigger diameter, we need to compare the given diameters of a red blood cell and a platelet. The diameter of a red blood cell is approximately 2.33×10^−6 m, while the diameter of a platelet is approximately 0.0000075 m.
First, let's compare the two given diameters:
Red blood cell diameter = 2.33×10^−6 m
Platelet diameter = 0.0000075 m
To compare these diameters, we can subtract the diameter of the red blood cell from the diameter of the platelet:
0.0000075 m - 2.33×10^−6 m = 0.0000075 m - 0.00000233 m = 0.00000517 m
The result is 0.00000517 m.
Therefore, the platelet has a bigger diameter than the red blood cell by approximately 5.17 x 10^-6 m.
The correct answer is option D: a red blood cell has a bigger diameter than a platelet by 5.17 x 10^-6 m.
