Answer:
•(HOMOLOGOUS STRUCTURE)the front leg of a horse and the wing of a bat
•(ANALOGOUS STRUCTURE); the wings of a dragonfly and the wings of a bat
•(VESTIGIAL STRUCTURE); the hip and shoulder bones of snakes
Explanation:
Homologous structures refers to those organs or skeletal elements of animals and organisms that posses some connection to a common ancestor. Though the structures may not have the same appearance or function.Example of homologous structures can be noticed in these organisms;
1.) the wings of a bat
2.)the arms of a human.
Both Bats and humans have ancestry that is common and they are both mammals with similar internal bone structure.
Analogous structures reffer to as biological structures with similar functions but from evolutionary origin that are different.Analogous can also be described as having similar structures in unrelated organisms. These structures are similar because perform same job, not as a result of sharing common ancestry.
Vegitive structures that have no feasible function and seems to be residual parts from thier past ancestor. They include: the pelvic bone of a snake, and the wings of flightless birds.
