1.	Life ScienceBacteria can divide in every 20 minutes. So, 1 bacterium can multiply to 2 in 20 minutes, 4 in 40 minutes, and so on. How many bacteria will there be in 6 hours? Write your answer using exponents, then evaluate.Most Bacteria reproduce by a type of simple cell division known as binary fission. Each species reproduce best at a specific temperature and moisture level.
Answer» We know that, 1 h = 60 min 6 h = 60 x 6 min = 360 min Given, a bacteria doubles itself in every 20 min. Number of times it will double itself = 360 min/20 min = 18 ∴ Bacteria will there in 6 h = 2 x 2 x 2 x … x 2 (18 times) =2¹⁸

Answer»

We know that, 1 h = 60 min

6 h = 60 x 6 min = 360 min Given, a bacteria doubles itself in every 20 min.

Number of times it will double itself = 360 min/20 min = 18

∴ Bacteria will there in 6 h = 2 x 2 x 2 x … x 2 (18 times) =2¹⁸
