answer:Based on the given characteristics, the newly discovered organism belongs to the taxonomic rank of Class. Specifically, it would be classified under the Class Aves (birds). Here's the breakdown of the classification: - Multicellular: This characteristic places the organism in the domain Eukarya. - Backbone: This characteristic places the organism in the phylum Chordata. - Feathers and lays eggs: These characteristics place the organism in the class Aves (birds). So, the correct taxonomic rank for this organism is Class, and it belongs to the Class Aves.

answer:Felis catus, commonly known as the domestic cat, belongs to the species taxonomic rank. Here is the complete taxonomic classification for Felis catus: - Kingdom: Animalia - Phylum: Chordata - Class: Mammalia - Order: Carnivora - Family: Felidae - Genus: Felis - Species: Felis catus

answer:Arion vulgaris, commonly known as the Spanish slug, belongs to the taxonomic rank of species. The characteristics that led to this determination are as follows: 1. Domain: Eukarya - Arion vulgaris is a eukaryotic organism, meaning it has cells with a nucleus and membrane-bound organelles. 2. Kingdom: Animalia - It is an animal, as it is a multicellular, heterotrophic organism that lacks cell walls. 3. Phylum: Mollusca - Arion vulgaris is a mollusk, characterized by a soft body, muscular foot, and a mantle that secretes a shell in some species. 4. Class: Gastropoda - It is a gastropod, which includes snails and slugs, characterized by a single, coiled shell (reduced or absent in some species) and a distinct head with sensory organs. 5. Order: Stylommatophora - This order includes terrestrial gastropods with two pairs of tentacles and a pneumostome (breathing hole) on the right side of the body. 6. Family: Arionidae - Arion vulgaris belongs to the family Arionidae, which includes roundback slugs with a small or absent shell and a well-developed mantle. 7. Genus: Arion - The genus Arion comprises slugs with a rounded body, no external shell, and a distinct color pattern. 8. Species: Arion vulgaris - This species is characterized by its large size (up to 15 cm when extended), orange-brown to reddish-brown color, and preference for moist habitats. The combination of these characteristics, from domain to species, allows us to classify Arion vulgaris as a distinct species within the taxonomy of living organisms.

answer:The correct taxonomic rank for the organism Ursus arctos is the species level. In the binomial nomenclature system, the first part of the name (Ursus) represents the genus, and the second part (arctos) represents the species. The species level is the most specific rank in the taxonomic hierarchy, and it groups together organisms that are closely related and can interbreed to produce fertile offspring. Organisms within the same species share similar physical and genetic characteristics. In the case of Ursus arctos, it is commonly known as the brown bear and includes several subspecies that inhabit various regions across the Northern Hemisphere.
