2. What​ ​is​ ​the​ ​main​ ​aim​ ​of​ ​the​ ​study​ ​of​ ​systematics? A. To​ ​calculate​ ​how​ ​many​ ​organisms​ ​there​ ​are​ ​on​ ​Earth B. To​ ​understand​ ​the​ ​evolutionary​ ​relationship​ ​of​ ​biological​ ​organisms C. To​ ​create​ ​a​ ​naming​ ​system​ ​for​ ​biological​ ​organisms D. None​ ​of​ ​the​ ​above

C. To​ ​create​ ​a​ ​naming​ ​system​ ​for​ ​biological​ ​organisms

Explanation:

Its main objectives are to provide scientific names for organisms, to describe organisms, to preserve collections of organisms, to provide and apply classification systems, to help identify organisms, to determine the distributions of organisms, to investigate the evolutionary histories of organisms, and to study the environmental adaptations of organisms.1

Systematics is sometimes used interchangeably with taxonomy. This is because, taxonomy is a branch of science concerned also in finding, describing, classifying, and naming organisms, including the studying of the relationships between taxa and the principles underlying such a classification. However, systematics is more encompassing than taxonomy. The latter does not include the study of evolutionary histories and the environmental adaptations of organisms.

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell
