This could indicate that immediately after 8 h the population would arrive at a million cells and soon after 43 h, the quantity of cells made will be akin to the amount of World earth! The moment nutrients begin to deplete, the exponential growth is slowed down as well as the amounts of cells in the general population stays stable; This is actually the third stage known as the stationary period.
