The correct answer is skeletal development resulting in the movement of amphibians onto land and possibly evolved from lobe-finned fishes.
The initial lobe-finned fishes are bony fish with lobed, fleshy, paired fins that are connected with the body by a solitary bone. The fins of the lobe-finned fishes vary from those of all other fish in that each is borne on a lobe like, fleshy, scaly stalk protruding from the body.
This skeletal development will show that the species first developed in water and then gradually move onto the land and ultimately developed as species of land.
The two plates grab onto each other and lock in place is not a resulting situation of two plates colliding at a convergent boundary. When two plates colliding at a convergent boundary, what happenes is that one of the boundary either goes under or on top of the under, in order to release the energy that the two have stored because of the collision.
I think its the c. archaebacteria because there are hundreds of species of archaebacteria living under the sea.....
and bacteria is harmful to all lifes of species..
The substance is pure depending on which atoms bond.
