Question

which is the best way to complete the text? the tiktaalik roseae, an aquatic creature that lived roughly 375 million years ago, is the first known species to have developed characteristics of four - legged animals while still retaining the features typically associated with ______, scales, and gills. options: fish. fins; fish: fins; fish; fins

Explanation:

This colon format correctly introduces a list of fish-associated features (fins, scales, gills) in parallel structure, matching the text's need to list traits consistently. The semicolon option would disrupt the list flow, and the period option creates a grammatically incorrect fragment.

Answer:

fish: fins
