Question

transitional species
which of the following features were present in the transitional species between amphibian tetrapods and the fishes?
multiple choice
lungs, fins, and scales
fins, simple wrist bones, and expanded ribs
fins, rounded head with eyes on the side, and a neck
a flat head with eyes on the top, fins, and scales

Explanation:

Transitional species between amphibian tetrapods and fishes had characteristics of both groups. Fins are fish - like, simple wrist bones are an early tetrapod - like feature, and expanded ribs are also related to the transition from aquatic to more terrestrial life. Lungs are more developed in later tetrapods and not typical of early transitional forms. A rounded head with eyes on the side and a neck is more of a developed tetrapod feature. A flat head with eyes on the top is more common in some fish but not characteristic of the key transitional features.

Answer:

fins, simple wrist bones, and expanded ribs
