Answer:
B. natality + immigration = mortality + emigration
Explanation:
Migration refers to the movement of a group of people from one geographical region (location) to another geographical destination in search of better living conditions, work or social amenities.
Migration selectivity can be defined as the likelihood or tendency that a subset (part) of a group of people are going to move (migrate) out of a particular geographical location or area.
Some of the factors that influence migration selectivity are income level, age, education, gender etc.
Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.
Mathematically, the population change equation is given by the formula;
Population Change = (Natality - Mortality) + (Immigration - Emigration)
Therefore, the equation which would create a stable population is given by the formula;
Natality + immigration = mortality + emigration.

There are various imaging techniques in collecting information about the brain and its adjacent structures. To enumerate, there are the cranial ultrasound (for children with cranial sutures that are not closed yet), cranial CT-scan, cranial MRI, brain PET scan, and cranial functional MRI. Only the brain PET scan and cranial functional MRI can collect information about the brain function by detecting fluorodeoxyglucose (FDG) in the brain as this lights up in functional areas of the brain in PET scan; and by detecting brain activity through changes in blood flow in cranial functional MRI.
<em>While it is not an imaging technique, electroencephalogram or EEG can detect brain function.</em>
