A) \[175\times {{10}^{5}}\]
B) \[125\times 10s\]
C) \[48\times {{10}^{5}}\]
D) \[32\times {{10}^{5}}\]
Correct Answer: D
Solution :
Bacteria generally divides by binary fission, in this one cell divide to produce two cells \[1\times {{10}^{5}}cells\xrightarrow[1st\,div.]{{}}2\times {{10}^{5}}\xrightarrow[2\,nd\,div.]{{}}\] \[4\times {{10}^{5}}\xrightarrow[3rd\,div.]{{}}8\times {{10}^{5}}\xrightarrow[4th\,div.]{{}}16\times {{10}^{5}}\] \[\xrightarrow[5th\,div.]{{}}32\times {{10}^{5}}\] So cell concentration per mL after 17S minutes will be\[32\times {{10}^{5}}\].
