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

Answer 1

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).

Answer 2

Millimeter is the smallest and blood cells are really small. I’d say something smaller though, if that’s an option.
