Question

In frogs, notochord is present in the form of

• A. Nucleous pulposus
• B. Intervertebral disc
• C. Vertebral
• D. Segment

Answer 1

The correct option is C Vertebral

Members of sub-phylum Vertebrata possess notochord during embryonic period and this notochord is later replaced by cartilaginous or bony vertebral column in the adult phase. Since amphibians are members of Sub-phylum vertebrata thus they have notochord in form of vertebral column.

So, the correct answer is 'Vertebral'.
