Within the subphylum Vertebrata, organisms are classified into distinct taxonomic classes based on anatomical traits, thermoregulation, and reproductive strategies. Match each vertebrate class on the left with its defining diagnostic characteristics on the right.
- Class AmphibiaEctothermic vertebrates with moist, permeable skin lacking scales that typically undergo metamorphosis from aquatic larvae to terrestrial adults.
- Class ReptiliaEctothermic vertebrates covered in dry, keratinized epidermal scales that typically lay leathery-shelled amniotic eggs on land.
- Class AvesEndothermic vertebrates characterized by feathers, bipedal anatomy, four-chambered hearts, and hollow lightweight bones.
- Class MammaliaEndothermic vertebrates characterized by mammary glands for nursing young, insulating hair or fur, and three middle ear ossicles.
Cevap
Class Amphibia matches ectothermic vertebrates with permeable skin and aquatic-to-terrestrial metamorphosis; Class Reptilia matches ectothermic vertebrates with dry keratinized scales and amniotic eggs; Class Aves matches endothermic vertebrates with feathers and hollow bones; Class Mammalia matches endothermic vertebrates with mammary glands, hair, and three middle ear bones.
Vertebrate taxonomy separates tetrapods into distinct classes based on key evolutionary adaptations: Amphibia represents the transition to land with water-dependent larval stages and cutaneous respiration; Reptilia evolved waterproof keratin scales and amniotic eggs; Aves evolved high metabolic rates, feathers, and hollow skeletal systems for flight; and Mammalia evolved lactation, fur, and advanced cranial structures.
