Introduction:
Animal life has evolved in hundreds of millions of years on Earth. Some scientists claim that changing environmental conditions, like the accumulation of dissolved oxygen and ocean minerals or increased atmospheric oxygen, eventually allowed higher
Answer to Problem 1TY
The correct answer is option (e)bilateria, protostomia, ecdysozoa.
Explanation of Solution
Explanation/justification for the correct answer:
Option (e) Bilateria, Protostomia, Ecdysozoa.The correct hierarchy of divisions in the animal kingdom from most inclusive to least inclusive is Bilateria, Protostomia, Ecdysozoa. All animals are believed to be derived from a choanoflagellate-like ancestor. An animal categorized based on body plans and molecular data. So, the correct answer is option (e).
Explanation for incorrect answer:
Option (a)Deuterostomia, Protostomia, Ecdysozoa. The correct hierarchy of divisions in the animal kingdom from most inclusive to least inclusive is Bilateria, Protostomia, Ecdysozoa. All animals are believed to be derived from a choanoflagellate-like ancestor. An animal categorized based on body plans and molecular data. Thus, from most inclusive and least inclusive Deuterostomia, Protostomia, Ecdysozoa is not the correct hierarchy of divisions in the animal kingdom. So, this is an incorrect option.
Option (b) Bilateria, Lophotrochozoa, Deuterostomia.The correct hierarchy of divisions in the animal kingdom from most inclusive to least inclusive is Bilateria, Protostomia, Ecdysozoa. All animals are believed to be derived from a choanoflagellate-like ancestor. An animal is categorized based on body plans and molecular data. Thus, from most inclusive and least inclusive, Bilateria, Lophotrochozoa, Deuterostomia is not the correct hierarchy of divisions in the animal kingdom. So, this is an incorrect option.
Option (c)Bilateria, Ecdysozoa, Protostomia.The correct hierarchy of divisions in the animal kingdom, from most inclusive to least inclusive is Bilateria, Protostomia, Ecdysozoa. All animals are believed to be derived from a choanoflagellate-like ancestor. An animal categorized based on body plans and molecular data. Thus, from most inclusive and least inclusive, Bilateria, Ecdysozoa, Protostomiais not the correct hierarchy of divisions in the animal kingdom. So, this is an incorrect option.
Option (d)Deuterostomia, Ecdysozoa, Bilateria.The correct hierarchy of divisions in the animal kingdom, from most inclusive to least inclusive is Bilateria, Protostomia, Ecdysozoa. All animals are believed to be derived from a choanoflagellate-like ancestor. An animal categorized based on body plans and molecular data. Thus, from most inclusive and least inclusive, Deuterostomia, Ecdysozoa, Bilateriais not the correct hierarchy of divisions in the animal kingdom. So, this is an incorrect option.

This clade is the sister taxon to reptiles. Adults are terrestrial and nocturnal, while the young are diurnal. Larval forms of most species are herbivorous while adults are insectivorous/carnivorous. The closest living relatives of avian reptiles. They are known as the "side necked" turtles. Have elongate, tapering snouts and, with the mouth closed, the 4th tooth on the lower jaw is visible. Most diverse and speciose clade of reptiles. Adults of this taxon are known to be cannibalistic on younger individuals. Possess teeth set in bony sockets and replace teeth throughout their lives.
