B Planaria, belongs to the phylum platyhelminthes and class turbellaria. The body is dorsoventrally flattened. Planaria possesses a high capacity of regeneration. It can be cut into pieces and each piece can regenerate into a complete organism. Cells at the location of wound site proliferate to form a blastema that will differentiate into new tissues and regenerate the missing parts of the piece of the cut Planaria. - Bioluminescence is the property of living organism to emit light is well-marked in ctenophores.

You are examining a water sample from a pond which is full of water plants. You find an animal which is cylindrical and shows a long filamentous structure at one end. It is not stationary and shows variety of movements. It could :
1 Paramecium
2 Tadpole
3 Hydra
4 Amoeba
Explanation:
C Hydra is a fresh water animal its body is hollow and cylindrical. To its one end (Hypastome) are attached 4,6 , or 8 contractile projection (Filamentous) known as tentacles. Hydra shows a variety of movement. - Paramecium - Paramecium genus of microscopic single - called and free-living protozoans. - Tadpole - A Tadpole is the larval stage in the biological life cycle of an amphibian. - Amoeba - Amoeba is unicellular organism that has the ability to change its shape.

If Hydra is cut transversely in three equal parts then :
1 all three parts will die
2 regeneration will occur in all the three parts
3 regeneration will occur only in anterior
4 regeneration occurs only in middle part
Explanation:
B Hydra has a high potential of regeneration. This was first established by Abraham Trembloy in 1744. If a living hydra is cut into two or three or more very small pieces, every piece develops into a new individual.

1 Only 2
2 Only 1
3 1 and 2

Explanation:
D Hydra nematocysts are unique in storing energy for discharge in the capsule wall, which is elastically stretched by an extreme osmotic pressure. - The gastrodermins lines the gastrovascular cavity in Hydra and is associated with the digestion.
