Answer 1

Hint: Nomenclature, is a system of naming organisms. Naming is done as per the rules by international committees in the fields of zoology, botany, bacteriology, and virology.

Complete answer:
The International Code of Nomenclature of Prokaryotes governs the formation and use of the scientific names of prokaryotes. For naming, we need to take into consideration the rules of the International Code of Botanical Nomenclature. As per the rule, the scientific names should be written in Latin words. The rank higher than genus generally ends with a single, standardised suffix. This offers a great advantage to biologists in text mining and database infrastructure in identifying and linking to the rank for which the scientific name is being used. The Class rank offers an exception where a standardised suffix has been proposed (-ia) and it is also a suffix used at the genus rank. So, even though there is much freedom of choice in names at the rank of genus and species, the scientific names above the genus rank are more restrictive and regulated.

Rank	Suffix	Example
Division	Phyta	Tracheophyta
Class	Opsida	Magnoliopsida
Order	ales	Sapindales
Family	Aceae	Anacardiaceae
Subfamily	oideae	-
Genus	-	Mangifera
Species	-	indica

Note:
Rules for nomenclature:
1) The Binomial nomenclature rule says that the name of any species should consist of two names:
Generic name- Name of the genus
Specific name- Trivial name
Example: Mango- Mangifera indica
2) In-plant nomenclature generic name and specific name should not be the same i.e. tautonyms are not allowed. Example: Mangifera mangifera
3) Tautonyms are allowed in animal nomenclature (ICZN-International Code of Zoological Nomenclature). Example: Naja naja (Indian cobra), Rattus rattus (Rat)
4) Length of a generic name or specific name should not be less than 3 letters and not more than 12 letters. Example: Mangifera indica
5) The first letter of generic name should be in capital letter and the first letter of specific name should be in small letter. Example: Mangifera indica
6) When written with freehand or typed, then a generic name and specific name should be separately underlined. But during printing, the name should be italicized.
7) Name of the scientist (who proposed nomenclature) should be written in short after the specific name Example: Mangifera indica Lin.
8) Name of a scientist should be neither underlined nor written in italics, but written in roman, letters (simple alphabets)
9) If any scientist has proposed the wrong name then his name should be written in the bracket and the scientist who corrected the name should be written after the bracket. Example: Tsuga canadensis (Lin.) Salisbury.
10) Scientific names should be derived from Latin or Greek languages because they are dead languages.
