Is regeneration in Hydra similar to regeneration in vertebrates, or is it fundamentally different in some way?

#Unit 5. Developmental Biology

Regeneration in Hydra occurs through a repatterning of existing cells by morphallaxis, unlike regeneration in vertebrates, which occurs through epimorphosis.
Regeneration in Hydra occurs through the reinitiation of cell division in existing cells, followed by repatterning of those cells, very much like regeneration in vertebrates.
Regeneration in Hydra occurs through the reinitiation of cell division in existing cells, followed by repatterning of those cells, which is totally different from regeneration in vertebrates.
Regeneration in Hydra occurs through the reinitiation of cell division in existing cells, followed by repatterning of those cells, whereas regeneration in vertebrates occurs through a process of repatterning of existing cells.
