Answer 2

Animals with a Dispersed-Nervous-System Type

a) Hydrozoan jellyfish (also known as hydrozoans or hydroids) have a dispersed-nervous-system type. They belong to the phylum Cnidaria and are characterized by their radial symmetry and tentacles. Hydrozoan jellyfish have a decentralized nervous system, with nerve cells scattered throughout their body. These nerve cells coordinate the jellyfish's movements and responses to stimuli. [[1]]

b) Annelids (segmented worms), including earthworms and leeches, have a dispersed-nervous-system type. Annelids have a ventral nerve cord that runs along the length of their body, with ganglia (clusters of nerve cells) located in each segment. This decentralized nervous system allows them to coordinate movement and respond to their environment. [[2]]

c) Sponges (phylum Porifera) do not have a centralized nervous system. Instead, they have a network of specialized cells called choanocytes that can respond to external stimuli. While sponges do not possess a complex nervous system like other animals, they are still capable of coordinating certain responses. [[3]]

d) Dipteran insects (two-winged insects) such as flies and mosquitoes have a dispersed-nervous-system type. Their nervous system consists of a series of ganglia connected by nerve cords. These ganglia are responsible for coordinating the insects' movements and responses to stimuli. [[4]]

e) Gastropod mollusks (belonging to the class Gastropoda) have a dispersed-nervous-system type. They possess a series of ganglia connected by nerve cords, allowing them to coordinate movement and respond to their environment. Examples of gastropod mollusks include snails and slugs. [[5]]

Please note that while these animals have a dispersed-nervous-system type, the level of complexity and organization of their nervous systems may vary.
