A) \[175\times {{10}^{5}}\]
B) \[125\times {{10}^{5}}\]
C) \[48\times {{10}^{5}}\]
D) \[32\times {{10}^{5}}\]
Correct Answer: D
Solution :
As we know that bacterium divided after every 35 minutes through simple mitotic division Therefore, number of divisions are \[\frac{175}{35}=5\] Since, one bacterium on division produces two cells so, cell concentration after 175 minutes will be \[\begin{align} & ={{10}^{5}}\times \,{{(20)}^{5}} \\ & =32\times {{10}^{5}} \\ \end{align}\]
