One of the characteristic of Hydra is :
1 predation
2 metamerism
3 hibernation
4 mimicry
Explanation:
A One of the characteristic of Hydra is predation because, it is exclusively carnivorous. - Hydra obtained food as a predator. - Prey are mostly aquatic animal like insects and egg of small fish etc.

Hydra is :
1 triploblastic, radial symmetrical and acoelomate
2 triploblastic, radial symmetrical and coelomate
3 diplobalstic, radial symmetrical and acoelomate
4 diploblastic, radial symmetrical and coelomate
Explanation:
C Hydra belong to class Hydrozoa of Cnidarians. Cnidarians have radial symmetry and diploblastic body plan. They are acoelomate and have a central digestive cavity (gastrovasclar cavity). In Hydra, tubular body shows polyp stage, $1 / 3$ part of body wall is made by ectodermal cells and $2 / 3$ part by endodermal cells. In between endoplasm and ectoplasm non cellular jelly like mesoglea is present for attachment of two layers. It has a single opening to serve as both mouth and anus.

How many ovum are developed in ovary of Hydra ?
1 Two
2 Many
3 One
4 Three
Explanation:
C Hydra can reproduce both asexually and sexually. It produces asexually by budding and sexually by the formation of gametes. A bud from the tubular body of an adult develops a mouth and tentacles. The male reproductive organ produces sperms and the females reproductive organ produces a single egg, a fusion of which result in the formation of zygote, no larval stage found, development is direct.

Hydra does not perform locomotion by :
1 looping
2 somer saulting
3 jet propulsion
4 walking
Explanation:
C Hydra is generally sessile or sedentary, but they move for hunting. Hydra perform locomotion by looping, walking and somer saulting but does not perform jet propulsion. Jet propulsion is that they contract their hollow saucer shaped bodies to force water out which propels them forward.
