Answer 1

Answer =

The levels in the modern system of biological classification -has 8 main levels.

Domain -Is the most inclusive of the levels.Domains are used to distinguish between the cell types .current system recognizes three domains: Bacteria,Archaea and Eukarya.

Kingdom - domains are further broken into kingdoms.The current system recognizes six kingdoms:Eubacteria,Archaebacteria,Plantae,Animalia,Fungi and protista.

Phylum - the next division would be the phylum.

Class - Several related classes make up a phylum.

Order- Classes are further divided into orders.

Family - The next level of classification that orders are divided into are families.

Genus - A genus is agroup of closely related species.the genus name is the first part of the scientific name of an organism.

Species -Each species has a unique identifier that describes only that species.

At each level, identify the name of the group that includes humans are as follows:

Kingdom = Animalia

Subkingdom - Eumetazoa

Phylum- Chordata.

class -Mammalia

Order- Primates

Family -Hominidae

Genus - Homo

Species- Homo sapiens sapiens Linnaeus.
