To determine which blood component has a bigger diameter, we compare the diameters of the platelet and red blood cell.
The diameter of a platelet is approximately 2.33×10^−6 m.
The diameter of a red blood cell is 0.0000075 m.
To compare the two diameters, we convert all the values to scientific notation with the same exponent:
Platelet diameter: 2.33×10^−6 m = 2.33×10^(-6) m
Red blood cell diameter: 0.0000075 m = 7.5×10^(-6) m
From this comparison, we can see that the red blood cell has a bigger diameter, with a difference of 7.5 - 2.33 = 5.17×10^(-6) m.
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)
