Question

The diameter of a bacterial cell is 1.5 microns. Which of the following represents the diameter of the cell in meters?
(Note: 1 micron = 1 millionth of a meter)

• A. 150 m
• B. 150000 m
• C. 0.0000015 m
• D. 0.000015 m

Answer 1

The correct option is C 0.0000015 m

1 micron = 1 millionth of a meter $=1\times {10}^{-6}m$
1.5 microns$=1.5\times {10}^{-6}m$
$=0.0000015m$
