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 platelet has a bigger diameter than a red blood cell by 5.17×10^−6 m.
A platelet has a bigger diameter than a red blood cell 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 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.
To determine which one has a bigger diameter and by how much, we can compare the diameters of a platelet and a red blood cell.
Platelet diameter = 2.33×10^−6 m
Red blood cell diameter = 0.0000075 m or 7.5×10^−6 m (since 0.0000075 m can be converted to scientific notation)
Now subtract the diameter of the platelet from that of the red blood cell to determine the size difference:
Red blood cell diameter - Platelet diameter = 7.5×10^−6 m - 2.33×10^−6 m = 5.17×10^−6 m
Since 5.17×10^−6 m is a positive number, it means the red blood cell's diameter is larger than that of the platelet.
Therefore, the correct statement is:
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.
