To find which blood component has a bigger diameter and by how much, we can compare the diameters of the platelet and red blood cell.
1. **Diameter of a platelet**: \(2.33 \times 10^{-6} \, \text{m}\)
2. **Diameter of a red blood cell**: \(0.0000075 \, \text{m}\) (which can also be written as \(7.5 \times 10^{-6} \, \text{m}\))
Now, we compare the two diameters:
- Diameter of a red blood cell: \(7.5 \times 10^{-6} \, \text{m}\)
- Diameter of a platelet: \(2.33 \times 10^{-6} \, \text{m}\)
To find the difference:
\[
7.5 \times 10^{-6} \, \text{m} - 2.33 \times 10^{-6} \, \text{m} = (7.5 - 2.33) \times 10^{-6} \, \text{m} = 5.17 \times 10^{-6} \, \text{m}
\]
So, a red blood cell has a bigger diameter than a platelet by \(5.17 \times 10^{-6} \, \text{m}\).
Thus, the correct response is:
**A red blood cell has a bigger diameter than a platelet by \(5.17 \times 10^{-6} \, \text{m}\).**
1. **Diameter of a platelet**: \(2.33 \times 10^{-6} \, \text{m}\)
2. **Diameter of a red blood cell**: \(0.0000075 \, \text{m}\) (which can also be written as \(7.5 \times 10^{-6} \, \text{m}\))
Now, we compare the two diameters:
- Diameter of a red blood cell: \(7.5 \times 10^{-6} \, \text{m}\)
- Diameter of a platelet: \(2.33 \times 10^{-6} \, \text{m}\)
To find the difference:
\[
7.5 \times 10^{-6} \, \text{m} - 2.33 \times 10^{-6} \, \text{m} = (7.5 - 2.33) \times 10^{-6} \, \text{m} = 5.17 \times 10^{-6} \, \text{m}
\]
So, a red blood cell has a bigger diameter than a platelet by \(5.17 \times 10^{-6} \, \text{m}\).
Thus, the correct response is:
**A red blood cell has a bigger diameter than a platelet by \(5.17 \times 10^{-6} \, \text{m}\).**
