To determine which blood component has a bigger diameter, we will first compare the diameters of a platelet and a red blood cell using the given values.
- Diameter of a platelet: \(2.33 \times 10^{-6} , \text{m}\)
- Diameter of a red blood cell: \(7.5 \times 10^{-6} , \text{m}\)
Now, let's compare the two diameters:
-
Convert the red blood cell diameter into scientific notation:
- The diameter of a red blood cell is already in scientific notation as \(7.5 \times 10^{-6} , \text{m}\).
-
Compare the two:
- We can see that \(7.5 \times 10^{-6} , \text{m}\) (red blood cell) is greater than \(2.33 \times 10^{-6} , \text{m}\) (platelet).
Now, let's calculate approximately by how much the red blood cell is larger than the platelet:
\[ \text{Difference} = \text{Diameter of red blood cell} - \text{Diameter of platelet} \]
\[ \text{Difference} = 7.5 \times 10^{-6} , \text{m} - 2.33 \times 10^{-6} , \text{m} \]
\[ \text{Difference} = (7.5 - 2.33) \times 10^{-6} , \text{m} = 5.17 \times 10^{-6} , \text{m} \]
Thus, a red blood cell has a bigger diameter than a platelet by approximately \(5.17 \times 10^{-6} , \text{m}\).
The correct answer is:
A red blood cell has a bigger diameter than a platelet by \(5.17 \times 10^{-6} , \text{m}\).
