1.	The cell of a bacteria doubles in every 30 min. A scientist begins with a single cell. How many cells will be thereafter (a) 12 h (b) 24 h ?
Answer» a. Cell of a bacteria in 30 mins = 2 (double in every 30 minutes) So, cell of bacteria in 1 hour = 2² = 4 Cell of bacteria in 12 hours = 2^{2 x 12} = 2²⁴ b. Cell of bacteria in 24 hours = 2^{2 x 24} = 2⁴⁸

The cell of a bacteria doubles in every 30 min. A scientist begins with a single cell. How many cells will be thereafter (a) 12 h (b) 24 h ?

Answer»

a. Cell of a bacteria in 30 mins = 2 (double in every 30 minutes)

So, cell of bacteria in 1 hour = 2² = 4

Cell of bacteria in 12 hours = 2^{2 x 12} = 2²⁴

b. Cell of bacteria in 24 hours = 2^{2 x 24} = 2⁴⁸
