A white blood cell has a diameter of approximately 10 micrometers, or 0.01 um. A model represents its diameter as 5 um. what is the ratio of model size to actual size?

Option B. 500 : 1

Explanation:

The following data were obtained from the question:

Actual size = 0.01 μm

Mode size = 5 μm

Ratio of model to actual size =.?

The ratio of the model size to the actual size can be obtained as illustrated below:

Model size : Actual size => 5 : 0.01

Model size/Actual size => 5 / 0.01

Model size/Actual size => 500/1

Model size : Actual size => 500 : 1

From the above illustration, the ratio of the model size to that of the actual size is 500 : 1
