Answer 1

Hydra has a well-developed capacity of regeneration.

Regeneration is a general process of growth by which some organism replace or restore lost and amputated body parts when cut.

New molecules are continuously being generated and degraded with turnover times, even in nerve cells, which cannot divide, there is an endless flow of cytoplasm from the cell body out into the nerve fibres themselves.
