Question

which of these are most likely homologous structures? bat wing dragonfly wing tyrannosaurus arm bat wing and dragonfly wing bat wing and tyrannosaurus arm dragonfly wing and tyrannosaurus arm bat wing, dragonfly wing, and tyrannosaurus arm

Explanation:

Homologous structures share a common embryonic origin and basic bone structure, despite different functions. Bats (mammals) and Tyrannosaurus (dinosaurs, ancestors of birds) are both vertebrates with forelimbs derived from the same tetrapod ancestor—their structures have similar bone arrangements (humerus, radius, ulna, carpals). Dragonfly wings are invertebrates with no bone structure, so they are analogous (same function, different origin).
