A. the right answer is Domain
In biology, the domain (neolatinized in dominium) is in certain biological classifications the first level of rank above the kingdoms.
The classification of Carl Woese et al. (1977, 1990) distinguishes three supposedly monophyletic domains:
* the domain Eubacteria or Bacteria
* Archaebacteria or Archaea estate
* and the estate Eukaryota or Eucarya
These taxa have fundamental differences in their genomes.
B. the right answer is Phylum
In systematics, the phylum is the second level of classical classification of living species.
A branch was originally defined as a particular organizational plan.
Branching and division are synonyms but are not used in the same reigns.
Linnaean systematics is close to phylogenetic systematics, which attempts to be closer to the genetic kinship links between species, using the tools of cladistics.
C. the right answer is Order
This fourth level of classification is particularly complex. It takes into account the morphology of each species (dentition, leg organization, etc.). For mammals, there are Carnivores (whose jaws are compatible with hunting, like the lion or the dog), Proboscidians (those who have a horn, that is to say elephants), Artiodactyls (which have an even number of fingers), rodents or primates.
D. the right answer is Family
This is the fifth level of classification. The classification is further refined by looking for commonalities between different species. In mammals, there are for example:
* Cervidae (Ruminant Artiodactyls that usually carry antlers, such as Deer);
* Bovidae (Cow, Goat and Sheep);
* Canids (Wolf, Dog, Fox);
* Hominids (like Man or Monkey);
* Leporidae (like the Rabbit);
E. the right answer is Species
It is the whole of the individuals who are interfeconds, that is to say that they are sufficiently similar to be able to reproduce between them.
The wolf and the German shepherd (wolf dog) can not reproduce; the German shepherd and the poodle yes.
As for the genus, the name (in Latin) of the species is always written in italics. However, it does not have a capital letter. For example, Bubo bubo is the scientific name of the Great Owl: Bubo is the name of the genus, and Bubo is the name of the species. Often, the name of genus and species can be identical, and that is why capitalization makes it possible to differentiate them.
