Yes, hydra have nuclei in their cells. These nuclei contain the genetic material of the organism and are essential for cell function and replication.
there are 2 layers. one for each side. like a sandwich and the layers are the bread. there are two of them so they can hold together the inside :]
It is not a single cell. It if a fully developed animal. It's a very cool one at that. It has stinging cells and tentacles with which it catches its prey. It can swim around or attach itself to something and stay there. It swallows its prey whole. Since it has only two layers of cells if you have one you can see through it and watch its prey being digested. How cool is that?
there are two layers inner and outer layer of a blood cell.......
two layers but so have three
forty-six layers
2 layers of lipids.
71 microscopic layers
This is a trick question. Because hydras are only two cell layers thick, they do not have a true circulatory system. The inner cell layer absorbs materials directly from their gastrovascular cavity. So a hydra doesn't have blood!

Hydra is in the phylum of the cnidarians which is a radical symmetry. so ectoderm, the outer layr which form the nerve sytem. Also, the endoderm, the inner layer are presented in the hydra.
