Answer 1

To determine which blood component has a bigger diameter, we can compare the diameters of the typical platelet and red blood cell.

The diameter of a platelet is approximately \(2.33 \times 10^{-6}\) m, and the diameter of a red blood cell is approximately \(7.5 \times 10^{-6}\) m.

Now, we can compare the two diameters:

• Diameter of red blood cell: \(7.5 \times 10^{-6}\) m
• Diameter of platelet: \(2.33 \times 10^{-6}\) m

To find the difference in diameter between the red blood cell and the platelet:

\[ \text{Difference} = 7.5 \times 10^{-6} , \text{m} - 2.33 \times 10^{-6} , \text{m} = (7.5 - 2.33) \times 10^{-6} , \text{m} = 5.17 \times 10^{-6} , \text{m} \]

Thus, a red blood cell has a bigger diameter than a platelet by \(5.17 \times 10^{-6}\) m.

The correct response is: A red blood cell has a bigger diameter than a platelet by \(5.17 \times 10^{-6}\) m.
