Through electrolysis , fluid balance in the cells can be achieved and it also helps to generate nerve impulses .
Answer:
1. Exoskeleton
2. Jointed appendages
Please find the explanation of the mentioned characteristics below
Explanation:
Arthropods are a group of animals that lack backbones i.e invertebrates but possess jointed legs. Arthropods as their name implies all belong to a large phylum called ARTHROPODA. They include insects, crustaceans etc. Due to their large number among other animal species, their outstanding variety etc, they are considered the MOST SUCCESSFUL animals.
This success of arthropods can be attributed to the characteristics they possess. Two of them are:
- EXOSKELETON: The outside skeleton possessed by members of these phylum supports their body, movement and general protection.
- JOINTED LEGS/APPENDAGES: Arthropods are virtually the only set of organisms that have jointed appendages giving them the adaptational ability to live and thrive in almost every habitat, if not all.
