Vedclass · Answer

(B) The population growth is determined by the formula: $	ext{Net Increase} = (	ext{Natality} + 	ext{Immigration}) - (	ext{Mortality} + 	ext{Emigration})$.Natality and immigration are factors that increase the population size.Mortality and emigration are factors that decrease the population size.Given values:$	ext{Natality} = 250$$	ext{Immigration} = 20$$	ext{Mortality} = 240$$	ext{Emigration} = 30$$	ext{Net Increase} = (250 + 20) - (240 + 30) = 270 - 270 = 0$.Therefore, the net increase in the population is zero.

$A$ biologist studied the population of rats in a barn. He found that the average natality was $250$, average mortality $240$, immigration $20$ and emigration $30$. The net increase in population is
