Phase of accelerated growth of logistic growth curve is . . . . . . .

The formula for exponential population growth is $:-$

The exponential phase of human population growth started approximately in which year (in $A.D.$)?

The given population growth curve represents the logistic growth curve. In this curve,identify what $A$,$B$,and $C$ indicate.

The asymptote stage of a population is the stage in which the population is:

$A$ population of $500$ experiences $55$ births and $5$ deaths during a one-year period. What is the reproductive rate for the population during the one-year period?
