Which one of the following describes correctly the homologous structures?
Options
- Aorgans with anatomical similarities, but performing different functions
- Borgans with anatomical dissimilarities, but performing same function
- Corgans that have no function now, but had an important function in ancestors
- Dorgans appearing only in embryonic stage and disappearing later in the adult
Correct answer
A. organs with anatomical similarities, but performing different functions
Step-by-step solution
The organs which have the same structure and origin but look different and perform different functions are called homologous organs. The organs which have the same function and are superficially alike but are quite different in their fundamental structure and embryonic origin are called analogous organs.
