Their cytoplasm and cellular contents are enclosed within a cell membrane. Their DNA is packaged into a central cellular compartment called the nucleus.

Does an amoeba have a defined boundary?

We define and characterize the extended boundary of an amoeba, which is sensitive to some degenerations that the topological boundary does not detect. This gives rise not only to new structural results in amoeba theory, but in particular allows us to compute hypersurface amoebas via their boundary in any dimension.

Does amoeba have internal organization?

What is found in hydra?

Hydra are simple invertebrates, with two layers of body cells. They live in fresh water. Their body is radially symmetric. They have a central cavity through which they take in food and expel waste. Hydras can be found in almost any unpolluted body of water.

What reason may limit the body size of Hydra?

For exoskeletons, it is difficult to regulate temperature and also limits growth. The exoskeleton must shed in order for the organism to grow and this limits the size of the organism.

Are hydras dangerous?
