If a population growing exponentially doubles in size in 3 years, what is the intrinsic rate of increase (r) of the population?

What are the main attributes of a population?

Population growth may be exponential or logistic. Differentiate between them.

The population of a country doubles in 50 years. How many years will it be five times as much? Assume that the rate of increase is proportional to the number inhabitants. (hint: log2=0.6931, log5=1.6094)

For the reaction A + BrarrC , itIs found that doubling the concentration of A Increases the rate by 4 times, and doubling the concentration of B doubles the reaction rate. What is the overall order of the reaction?

What do we learn from identification of individuals and populations?
