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. A red blood cell has a bigger diameter than a Platelets by 9.83 × 10^-⁶ m.
B. A Platelet had a bigger diameter than a red blood cell by 5.17 × 10^-⁶ m
C. A platelets has a bigger diameter than a red blood cell by 9.83 × 10^-⁶ m.
D. A red blood cell has a bigger diameter than a platelet by 5.17 × 10^-⁶ m.
The red blood cell has a diameter of 0.0000075 m, which can be written in scientific notation as 7.5 × 10^-⁶ m.
Comparing the two diameters, we can see that the diameter of a platelet is smaller than the diameter of a red blood cell. Therefore, the correct answer is D. 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 compare the diameters of platelets and red blood cells:
- The diameter of a platelet is approximately 2.33 × 10^-⁶ m.
- The diameter of a red blood cell is approximately 0.0000075 m.
Comparing these values, we can see that the diameter of a red blood cell is larger than the diameter of a platelet.
To find the approximate difference in diameter between the two, we subtract the diameter of a platelet from the diameter of a red blood cell:
0.0000075 m - 2.33 × 10^-⁶ m = 0.000005175 m
So, a red blood cell has a bigger diameter than a platelet by approximately 0.000005175 m.
Therefore, the correct answer is:
D. 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 the difference in diameter, we need to compare the diameters of platelets and red blood cells.
Given:
Diameter of a platelet = 2.33 × 10^-⁶ m
Diameter of a red blood cell = 0.0000075 m
Comparing the two diameters, we can see that 0.0000075 m is indeed larger than 2.33 × 10^-⁶ m. Now, we need to find the difference in diameter.
To calculate the difference in diameter, we subtract the diameter of the smaller component from the diameter of the larger component.
0.0000075 m - 2.33 × 10^-⁶ m = 0.000007497 m
So, the correct answer is:
A. A red blood cell has a bigger diameter than a Platelets by 0.000007497 m.
