Bats and birds are unrelated animals, yet they both evolved wings. by acquiring similar traits (i.e., wings) as they adapted to similar environments, these species exhibit convergent evolution through analogy present between the wings. Convergent evolution happens when two distantly related organisms acquire the similar traits in response to the similar habitat or niche.
A scientific theory. Obviously, the hypothesis would need a considerable amount of increased testing to be proven a scientific law. But, even so, it could become a theory.
I hope this helped you!
Guessing you mean "impulse".
It means to have a sudden strong desire to do something or a small amount of energy that moves from one area to another.

The role of the nucleolus is to make the monomer of of ribosomes, and ribosomes are used in mRNA to make protein. Therefore the nucleolus plays a major role in the process of making proteins for our body. <span />
