Select the incorrect statement:
1 In Hydra endocrinal organisation is composed of a network of neurons.
2 The neural system is better organised in insects, where a brain is present along with a single ganglia and neural tissues.
3 The neural system of all animals is composed of highly specialised cells called nephrons
4 All are incorrect.
Explanation:
All are incorrect. They can be corrected as (1) In Hydra neural organisation is composed of a network of neurons. (2) The neural system is better organised in insects, where a brain is present along with a number of ganglia and neural tissues (3) The neural system of all animals is composed of highly specialised cells called neurons

Nervous system of Hydra is composed of
1 Brain
2 Ganglion with nerves
3 Network of nerves
4 Well - developed nervous system
Explanation:
In Hydra, neural organisation comprises of network of neurons called nerve net. Nerve nets connects sensory photoreceptors and touch sensitive nerve cells located in the body wall and tentacles
