Final answer:
Immigration and emigration do not occur within a closed population.
Step-by-step explanation:
Immigration and emigration occur within a closed population.
The statement is false.
Immigration refers to the movement into an area to take up permanent residence, while emigration refers to movement out of an area to another place of permanent residence.
Both immigration and emigration involve the movement of individuals into or out of a population.
Therefore, they cannot occur within a closed population.
