Question

What will be the population size with in $48$ hours, if paramecium undergoes $4$ binary fissions in a day?

• A. $32$
• B. $256$
• C. $64$
• D. $512$

Answer 1

Answer: (B)

$256$

Within 48 hours( 2 days ), paramecium will undergo binary fission 8 times (4× 2). Each binary fission results in the production of two offspring from a single cell. Hence, the number of individuals in population after 48 hours will be 2${}^8$ = 256.

So, the correct option is '256'.
