How do they recomemerate?

Answer 1

It seems there might be a typo in your question. If you meant "How do they regenerate?", many organisms, such as certain species of starfish, salamanders, and planarians, can regrow lost body parts through a process called regeneration. This involves the activation of stem cells at the injury site, which then differentiate into the necessary cell types to form the new tissue. The process is often guided by complex signaling pathways and requires a suitable environment for successful regeneration. If you meant something else, please clarify!
