Platelets and red blood cells are components of the blood. A typical platelet and red blood cell have diameters of approximately 2.33×10−6 m and 0.0000075 m, respectively. Which blood component has a bigger diameter, and approximately by how much?(1 point) Responses A red blood cell has a bigger diameter than a platelet by 9.83×10−6 m. A red blood cell has a bigger diameter than a platelet by 9.83 times 10 superscript negative 6 baseline m. A red blood cell has a bigger diameter than a platelet by 5.17×10−6 m. A red blood cell has a bigger diameter than a platelet by 5.17 times 10 superscript negative 6 baseline m. A platelet has a bigger diameter than a red blood cell by 9.83×10−6 m. A platelet has a bigger diameter than a red blood cell by 9.83 times 10 superscript negative 6 baseline m. A platelet has a bigger diameter than a red blood cell by 5.17×10−6 m.

Answer 1

To determine which blood component has a bigger diameter, let's compare the diameters of platelets and red blood cells:

• 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, we can see that the red blood cell has a larger diameter. To find out how much larger, we will subtract the diameter of the platelet from the diameter of the red blood cell:

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

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

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