Answer 1

To determine which blood component has a bigger diameter, we need to compare the given diameters:

• 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 compare the two:

• Platelet: \( 2.33 \times 10^{-6} , \text{m} \)
• Red blood cell: \( 7.5 \times 10^{-6} , \text{m} \)

Clearly, \( 7.5 \times 10^{-6} , \text{m} \) is greater than \( 2.33 \times 10^{-6} , \text{m} \).

Now, let's calculate the difference in diameter:

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

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

Therefore, the correct response is:

A red blood cell has a bigger diameter than a platelet by 5.17 times 10 superscript negative 6 baseline m.
