The physical properties describes all matter. Physical properties are color, length, volume, odor, and density have same essence and definition for all matter the only thing which changes is the variation in composition and quantum in each matter that give different values for the same physical properties for different matter
Answer:
The bones are homologous structures
Explanation:
Homologous structures are the structure which are found similar in appearance in different organisms.
The homologous structures in different organism shows that they shared a common ancestor or they diverged from a common ancestor during course of evolution that is these homologous structures are the result of the divergent evolution.
In the given question, the bat, dolphin and the cat shows the same structure of bone which indicates that they have evolved from a common ancestor and is true as they all belong to mammals.
Thus, the bones are homologous structures is correct.
The answer to your question is D) punctuated equilibrium.
The theory of Punctuated Equilibrium states that extremes in the environment cause sudden evolution; a long period of time precedes the sudden evolutionary changes.
