Question

A protozoan reproduces by binary fission. What will be the number of protozoans in its population after six generations?

• A. $128$
• B. $24$
• C. $64$
• D. $32$

Answer 1

Answer: (C)

$64$

By binary fission, an individual protozoan will divide into two. In this way, after six generations their number will be 64.

1st division- 1-->2

2nd division- 2-->4

3rd division- 4-->8

4th division- 8-->16

5th division 16-->32

6th division- 32-->64

So, the correct answer is 64.
