Organism Organisation of neural system A. Vertebrae 1. More developed neural system. B. Insects 2. Simple neural organisation C. Hydra 3. Brain is present along with a number of ganglia and neural tissues D. Lower Invertebrae 4. Network of neurons
Options
- AA -3 , B -2 , C - 1, D - 4
- BA -4 , B -2 , C - 3, D -1
- CA -1 , B -3 , C -4 , D - 2
- DA - 1, B -2 , C -4 , D -3
Correct answer
C. A -1 , B -3 , C -4 , D - 2
Step-by-step solution
The neural organisation is very simple in lower invertebrates. For example, in Hydra it is composed of a network of neurons. The neural system is better organised in insects, where a brain is present along with a number of ganglia and neural tissues. The vertebrates have a more developed neural system.
