Platelets and red blood cells are components of the blood. A typical platelet and red blood cell hav diameters of approximately 2.33 × 10- m and 0.0000075 m, respectively. Which blood compone has a bigger diameter, and approximately by how much? (1 point)
O A platelet has a bigger diameter than a red blood cell by 9.83 × 10 6 m
O A platelet has a bigger diameter than a red blood cell by 5.17 x 10 ° m.
O A red blood cell has a bigger diameter than a platelet by 5.17 × 10 0 m.
O A red blood cell has a bigger diameter than a platelet by 0.83 × 10 0 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 and by approximately how much, we need to compare the diameters of a platelet and a red blood cell.
The diameter of a platelet is given as 2.33 × 10^-6 m.
The diameter of a red blood cell is given as 0.0000075 m.
Comparing these values, we can see that the diameter of a red blood cell is larger than the diameter of a platelet.
So, the correct answer is:
A red blood cell has a bigger diameter than a platelet by approximately 0.83 × 10^0 m.
To determine which blood component has a bigger diameter and by how much, we need to compare the given diameters of the platelet and the red blood cell.
The diameter of the platelet is approximately 2.33 x 10^(-6) m.
The diameter of the red blood cell is approximately 0.0000075 m.
To simplify the comparison, we can convert both values to scientific notation with the same exponent.
2.33 x 10^(-6) m can also be written as 2.33 x 10^(-6) x 10^(6) x 10^(-6) m = 2.33 x 10^0 m.
Therefore, the comparison becomes:
2.33 x 10^0 m (platelet) versus 7.5 x 10^(-6) m (red blood cell).
Comparing the exponents, we see that the platelet has a bigger diameter than the red blood cell.
Since the exponent in scientific notation represents the power of 10, we can calculate the difference in diameters by subtracting the exponents:
0 - (-6) = 0 + 6 = 6.
Now we convert this back to standard notation:
6 = 6 x 10^0.
Therefore, a platelet has a bigger diameter than a red blood cell by approximately 6 x 10^0 m, which simplifies to 6 m.
However, none of the given answer choices match this result. The given options have incorrect values or incorrect exponents.
