Question

multiple choice question
tetrapod vertebrates with porous skin, lungs, and a life cycle tied to water are called
o amphibians.
o reptiles.
o lampreys.
o ray - finned fishes.

Explanation:

Amphibians are tetrapod vertebrates. They have porous skin which can be used for gas exchange. They possess lungs (though some also respire through their skin). Their life cycle is tied to water as they typically lay eggs in water and have an aquatic larval stage (e.g., tadpoles of frogs). Reptiles have dry, scaly skin and are more adapted to life on land with their reproduction not as dependent on water (they lay amniotic eggs). Lampreys are not tetrapods (they are jawless fish). Ray - finned fishes are also not tetrapods and are fully aquatic with gills for respiration (not lungs in the adult stage in the typical sense for most ray - finned fishes).

Answer:

amphibians.
