Platelets and red bloods 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. A platelet has a bigger diameter than a red blood cell by 9.83 x 10^-6 m
2. A red blood cell has a bigger diameter than a platelet by 9.83 x 10^-6 m
3. A platelet has a bigger diameter than a red blood cell by 5.17 x 10^-6 m
4. A red blood cell has a bigger diameter than a platelet by 5.17 x 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.

Given:
Diameter of a platelet = 2.33 x 10^-6 m
Diameter of a red blood cell = 0.0000075 m = 7.5 x 10^-6 m

To solve this, we can subtract the diameter of the smaller component from the diameter of the larger component.

Diameter difference = Diameter of the larger component - Diameter of the smaller component

Diameter difference = 7.5 x 10^-6 m - 2.33 x 10^-6 m
Diameter difference = 5.17 x 10^-6 m

Therefore, the correct answer is option 4. A red blood cell has a bigger diameter than a platelet by 5.17 x 10^-6 m.

3. A platelet has a bigger diameter than a red blood cell by 5.17 x 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 approximately 2.33 x 10^-6 m (2.33 micrometers).
The diameter of a red blood cell is given as approximately 0.0000075 m (7.5 micrometers).

Comparing these values, we can see that the red blood cell has a bigger diameter than the platelet.

Therefore, the correct answer is:
2. A red blood cell has a bigger diameter than a platelet by 9.83 x 10^-6 m.
