homologous structures are those parts of an organism which have a similar structures, but have evolved to have different functions. these structures indicate that the organisms came from a common ancestor.
what makes the frog foot and bat wing homologous structures?

Explanation:

Homologous structures are defined by having a similar underlying anatomical structure (like bone arrangement) due to common ancestry, even if functions differ. The frog foot and bat wing share a similar skeletal (bone) structure (e.g., presence of comparable limb bones, digits' bone arrangement), showing they evolved from a common ancestor, which is the key trait of homologous structures.

Answer:

The frog foot and bat wing are homologous structures because they have a similar anatomical (bone) structure, indicating they evolved from a common ancestor, even though they have different functions (frog foot for locomotion on land/water, bat wing for flight).
