Answer:
The answer is a. homologous structures
Explanation:
Homologous Structures:
Structures that have<u> similar anatomy or similar structure</u> but have different functions are called homologous structures.
These structures indicate shared ancestry between the animals in question. This means that the structures may be used for different functions but they are encoded by same or similar genes.
The bones in the picture perform quite different functions and they might look different from the outside but as we look closer, the bone structure and joints are similar. This shows that all of these animals evolved from a common ancestor.
Cold blooded, lay eggs in water, and respire both by skin and lungs, and they have a three-chambered heart.
A bone cell, formed when an osteoblast becomes embedded in the matrix it has secreted.
