Cases preferentially ascertained from specific subpopulations.. What is syntax?. Word order. The manner in which a speaker or author constructs a sentence affects what the audience understands.. inverted order of an interrogative cues reader/listener to a question and creates tension.

Species distribution. Density . and size are useful measures for characterizing populations. Scientists gain additional insight into a species' biology and ecology from studying how individuals are spatially distributed. Dispersion or distribution patterns show the spatial relationship between members of a population within a habitat. Patterns are often characteristic of a particular species; they depend on local environmental conditions and the species' growth characteristics (as for plants) or behavior (as for animals).. unit: Patterns in human geography.
