To determine which blood component has a bigger diameter, we need to compare the diameters of platelets and red blood cells.
The diameter of a platelet is approximately \(2.33 \times 10^{-6}\) meters, and the diameter of a red blood cell is approximately \(0.0000075\) m, which can be expressed in scientific notation as \(7.5 \times 10^{-6}\) meters.
Now, let's compare the two:
- Platelet diameter: \(2.33 \times 10^{-6}\) m
- Red blood cell diameter: \(7.5 \times 10^{-6}\) m
Now we determine which one is bigger and by how much:
Difference in diameter: \[ (7.5 \times 10^{-6}) - (2.33 \times 10^{-6}) = 5.17 \times 10^{-6} \text{ m} \]
So, a red blood cell has a bigger diameter than a platelet by approximately \(5.17 \times 10^{-6}\) m.
The correct response is: A red blood cell has a bigger diameter than a platelet by \(5.17 \times 10^{-6}\) m.
