Assertion (A): It is necessary to know the life history of an ascidian to consider it a chordate. Reason (R): Ascidians exhibit retrogressive metamorphosis in which larval stages are in a degenerated condition.
1 Both and are true and is the correct explanation of .
2 Both and are true but is not the correct explanation of A.
3 is true but is false.
4 A is false but is true.
Explanation:
C An ascidian, also know as sea squirt is a marine invertebrate belonging to the phylum chordate. Despite its adult form appearing quits different from other chordates. The ascidian have notochord, which is a flexible rodlike structure providing support and dorsal nerve cord that eventually divelops into the spinal cord. These indicat the evolutionary connection to vertebrates and other chordates. Assidian or sea squirt exhibit retrogressive metamosiphosis. This means that during their development series of changes that result in the loss of certain structure, not larval stages.
