Q

What kind of symmetry does hydra have

40
Q

What kind of body form does hydra have

41
Q

When the mouth/anus is closed the gastrovascular cavity acts as a

A

Hydrostatic skeleton and restricts volume changes

42

For intracellular digestion

46
Q

Hydra has _______ between ectoderm and endoderm

47
