What is the growth rate of a Paramecium population in a pool if it increases from 50 individuals to 150 individuals in one hour?
Answer & explanation
Correct answer: option 4
To determine the growth rate of the Paramecium population, we can calculate the difference in population size divided by the time elapsed.
Initial population: 50 Paramecium Final population: 150 Paramecium Time elapsed: 1 hour
Growth rate = (Final population - Initial population) / Time elapsed Growth rate = (150 - 50) / 1 Growth rate = 100 / 1 Growth rate = 100
Therefore, the growth rate of the Paramecium population is 100 per hour.
The correct option is (d) 100 per hour.
