Answer:
Factor Analysis
Explanation:
Factor Analysis is a statistical procedure that can be used to identify clusters of behaviors (such as verbal skills, intelligence) that are related to a trait.
Factor analysis helps to accumulate a lot of data in many variables into a few variables which can be used for further analysis or study. The aim of factor analysis is to aggregate individual behaviors into a minimized number of factors.
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.

Answer:
blood because that is a part of your body bacteria
All the cells don't have all of the intracellular structures because each and every cell do not need each and every intracellular structure. The plant cells have chloroplasts because they need to convert the light energy into chemical energy via the process of photosynthesis, the animal cells, however, have no such need, therefore, the animal cells do not have chloroplasts. Also, the erythrocytes do not have the cellular organelles in them which are present in the other body cells, because there is no need for the cellular organelles in them. The large vacuoles in plant cells is also a great example. The plants need the vacuoles for the metabolic processes, while most animal cells have no need for them.
