Species
Species is the least inclusive taxonomic category, as it refers to a group of organisms that are capable of interbreeding and producing fertile offspring. It is more specific than higher taxonomic levels such as genus, family, or order.
The lowest level of classification in science is the species level. Organisms are classified into different species based on their ability to interbreed and produce fertile offspring.
To sort 10 organisms using couplets, you would need at least 4 couplets. This is because each couplet can divide the organisms into two groups at a time, cutting the number of remaining organisms in half with each comparison, until all 10 organisms are sorted.
Organisms from different domains (Bacteria, Archaea, and Eukarya) are the least similar to each other. These domains represent the highest level of biological classification and have significant differences in their cellular structures and functions.
Cells that do not contain a "true" nucleus are called prokaryotes. Sometimes eukaryotic cells are anucleate(no nucleus) when mature. Erythrocytes (red blood cells) in mammals are an example of eukaryotic cells that do not contain a nucleus when mature.

species
The highest level of classification, domain, has the least variety of organisms, encompassing only three major groups: Bacteria, Archaea, and Eukarya.
The classification group which has the least variety of organisms would be species. This is because it is the smallest class, and has been narrowed down beginning from kingdom.

The least level of classification in terms of Binomial Nomenclature in Taxonomy is Kingdom. There are seven different levels of classification. The acronym I use to remember is King Phillip Came Over For Great Spaghetti. This stands for: Kingdom Phylum Class Order Family Genus Species.
Species is the least inclusive taxonomic category, as it refers to a group of organisms that are capable of interbreeding and producing fertile offspring. It is more specific than higher taxonomic levels such as genus, family, or order.
Phylum includes the least variety of organisms. It is a higher taxonomic rank that groups together related classes and is below the domain and kingdom levels.
Sex cells contain half the number of chromosomes that body cells contain.
