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?
Responses
The red blood cell has a bigger diameter compared to the platelet. The difference in diameter is approximately 0.0000042 m.
To determine which blood component has a bigger diameter and by approximately how much, we can compare the diameters of the platelets and red blood cells.
The diameter of a platelet is approximately 2.33×10^-6 m.
The diameter of a red blood cell is approximately 0.0000075 m.
To compare the diameters, we can convert both values to scientific notation:
- The diameter of a platelet is 2.33×10^-6 m.
- The diameter of a red blood cell is 7.5×10^-6 m.
Comparing the values in scientific notation, we can see that the diameter of a red blood cell is larger than the diameter of a platelet.
By approximately how much is the red blood cell larger?
To find out, we can subtract the diameter of a platelet from the diameter of a red blood cell:
7.5×10^-6 m - 2.33×10^-6 m = 5.17×10^-6 m.
Therefore, the red blood cell is approximately 5.17×10^-6 m larger in diameter than a platelet.
