The correct answer is ​Evaporation.

Key Points

• Evaporation

The correct answer is All chordates have a ventral nerve cord.

1. Presence of Notochord: In the embryonic stage of chordate animals there is a solid stick-like structure (Just below the central nervous system and above the alimentary canal), this is called the notochord.
2. Presence of dorsal tubular nerve cord: In chordates, the nervous system is present at the dorsal surface of the body. The nerve cord is the hollow, tubular structure present just below the body wall and above the notochord.
3. Presence of pharyngeal gill clefts: In every chordate, there is a presence of a pair of lateral gill clefts in the wall of the pharynx for respiration. These may be present in any stage of its life span like in higher chordates gill clefts are present only in the embryonic stage not in adults.
4. Post-anal tail: It is the post-anal part of the body. The tail is reduced or absent in many adult chordates.
