Answer 1

The lungs of terrestrial vertebrates are homologous to the lungs of lungfish and the swim bladder of other fish.

Swim bladder

Step-by-step explanation:

The lungs of terrestrial vertebrates are homologous to the lungs of lungfish and the swim bladder of other fish

All bony fishes use gills to breathe, but they also have a swim bladder, a gas-filled organ that helps control their buoyancy. The swim bladder is believed to be homologous to the lungs of lungfish and terrestrial vertebrates.

For example, the lungfish possess both gills and lungs, showing a connection between the swim bladder and the lungs of terrestrial vertebrates.
