Platelets and red blood cells are components of the blood. A typical platelet and red blood cell have diameters of approximately
2.33 x 10^-6 m and 0.0000075 m, respectively. Which blood component has a bigger diameter, and approximately by how much? (1 point)
a. A platelet has a bigger diameter than a red blood cell by 9.83 × 10^-6 m
b. A red blood cell has a bigger diameter than a platelet by 5.17 × 10^-6 m.
c. A platelet has a bigger diameter than a red blood cell by 5.17 × 10^-6 m.
d. A red blood cell has a bigger diameter than a platelet by 9.83 × 10^-6 m
The correct answer is c. A platelet has a bigger diameter than a red blood cell by 5.17 × 10^-6 m.
To determine this, we compare the diameters of both components. The diameter of a platelet is given as 2.33 x 10^-6 m, and the diameter of a red blood cell is given as 0.0000075 m.
Comparing the two values, we can see that the platelet has the larger diameter (2.33 x 10^-6 m > 0.0000075 m). To find the difference in diameter between the two, we subtract the diameter of the red blood cell from the diameter of the platelet:
(2.33 x 10^-6 m) - (0.0000075 m) = 5.17 × 10^-6 m
Therefore, a platelet has a bigger diameter than a red blood cell by 5.17 × 10^-6 m.
To determine which blood component has a bigger diameter and by how much, we need to compare the diameters of a platelet and a red blood cell.
The diameter of a platelet is approximately 2.33 x 10^-6 m, and the diameter of a red blood cell is approximately 0.0000075 m.
Comparing these values, we can see that the diameter of a red blood cell is larger than that of a platelet.
To find the difference between their diameters, we subtract the diameter of a platelet from the diameter of a red blood cell:
0.0000075 m - 2.33 x 10^-6 m = 0.00000517 m
Therefore, the red blood cell has a bigger diameter than the platelet by approximately 5.17 × 10^-6 m.
Therefore, the correct answer is:
c. A platelet has a bigger diameter than a red blood cell by 5.17 × 10^-6 m.
To determine which blood component has a bigger diameter and by approximately how much, we compare the diameters of a platelet and a red blood cell.
The diameter of a platelet is given as 2.33 x 10^-6 m.
The diameter of a red blood cell is given as 0.0000075 m.
To compare these numbers, we can convert them to a common form.
The diameter of a platelet in scientific notation is 2.33 x 10^-6 m.
The diameter of a red blood cell in scientific notation is 7.5 x 10^-6 m.
Now, we can see that the diameter of a red blood cell is larger than the diameter of a platelet.
To find the difference in their diameters, we subtract the diameter of a platelet from the diameter of a red blood cell:
7.5 x 10^-6 m - 2.33 x 10^-6 m = 5.17 x 10^-6 m.
Therefore, option c is correct: A platelet has a bigger diameter than a red blood cell by approximately 5.17 x 10^-6 m.
