Answer 1

To determine which blood component has a bigger diameter and by how much, we need to compare the diameters of the platelet and the red blood cell.

• Diameter of a platelet: \( 2.33 \times 10^{-6} , \text{m} \)
• Diameter of a red blood cell: \( 0.0000075 , \text{m} = 7.5 \times 10^{-6} , \text{m} \)

Now, we can see that:

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

Next, we find the difference in diameter: \[ \text{Difference} = \text{Diameter of red blood cell} - \text{Diameter of platelet} \] \[ \text{Difference} = 7.5 \times 10^{-6} , \text{m} - 2.33 \times 10^{-6} , \text{m} = (7.5 - 2.33) \times 10^{-6} , \text{m} = 5.17 \times 10^{-6} , \text{m} \]

From this calculation, we can conclude that: A red blood cell has a bigger diameter than a platelet by \( 5.17 \times 10^{-6} \text{ m} \).

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