Biological Classification And System Of Classification Question 531
A 1 mL pipette can contain about
Options:
A) 1018 bacteria
B) 10^10 bacteria
C) 10^6 bacteria
D) 1012 bacteria
Show Answer
Answer:
Correct Answer: D
Solution:
Since 1 ml volume of pipette $ =10^{-6} $ cubic metre.
Diameter of 1 bacterium $ =10^{-3}mm=10^{-6}metre $ Hence the volume of 1 bacterium $ =10^{-6}\times 10^{-6}\times 10^{-6}=10^{-18} $ Therefore number of bacterium $ =\frac{{10^{-6}}}{{10^{-18}}}={10^{-6+18}}=10^{12}.
