Which change of state does the motion of the oranges most closely model?

Melting is change of state shows the motion of the oranges most closely model.

Explanation:

Change in the state depicted in the melting is similar to that of motion of the oranges. In this process the particle changes the state from solid to liquid.  when the molecules of the solid speed abundant that the motion kills the attraction by which the molecules can now move past each other as a liquid, melting occurs.  As the energy inside the solid goes up due to some external pressure or temperature, which leads to the increase of substance temperature to the melting point.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
