Question

A certain type of bacterial cell divides into two cells every hour. So, in a colony of these cells, the population doubles every hour.Which of the following describes the rate of population growth in this colony?

Answer 1

By given condition the bacterial cell divides into two cells every hour,

Thus, the population growth per hour is twice of what it was an hour ago.

Let 'x' be the population of the colony at a time instant 't'

Thus, the rate of population growth is :  x per hour

x number of of cells are formed every hour
