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)
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.

Question
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 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 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 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 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 red blood cell has a bigger diameter than a platelet by 5.17×10^−6 m.
To determine which blood component has a bigger diameter, we can compare the given diameters of the platelet and red blood cell.
The diameter of a typical platelet is approximately 2.33×10^(-6) m.
The diameter of a typical red blood cell is approximately 0.0000075 m.
Comparing the two values, we can see that the diameter of the red blood cell is larger than the diameter of the platelet.
To calculate the difference in diameter between the two, we subtract the diameter of the platelet from the diameter of the red blood cell:
0.0000075 m - 2.33×10^(-6) m ≈ 0.00000517 m
Therefore, the red blood cell has a larger diameter than the platelet by approximately 0.00000517 m.
To determine which blood component has a bigger diameter and the approximate difference in size, we compare the diameters of platelets and red blood cells.
Given in the question, the diameter of a platelet is approximately 2.33 × 10^(-6) m and the diameter of a red blood cell is approximately 0.0000075 m.
To compare these two values, we find the difference between them.
Subtracting the diameter of a platelet from the diameter of a red blood cell:
0.0000075 m - 2.33 × 10^(-6) m = 0.0000041665 m
Therefore, the difference in diameter between a red blood cell and a platelet is approximately 0.0000041665 m. Thus, the red blood cell has a larger diameter by approximately 0.0000041665 m.
