3. Which of the following units of measure should be used to measure the diameter of a red
blood cell?
A:centimeter
B:meter
C:kilometer
D:millimeter

Respuesta :

Millimeter is the smallest and blood cells are really small. I’d say something smaller though, if that’s an option.
You know that in 1 mm^3 blood about 4-5 million red bloods are found. That’s why you can measure the diameter of red blood cell in millimetres (mm).
