Question

Select the correct labeling for the given diagram:

• A. a- notochord, b- mouth, c- gill slit, d- neural tube, e- notochord
• B. a- gills slits, b- anus, c -mouth, d -neural tube, e -notochord
• C. a- gill slits, b- mouth, c- anus, d- neural tube, e -notochord
• D. a- gill slits, b- mouth, c- anus, d- notochord, e- neural tube

Answer 1

The correct option is C a- gill slits, b- mouth, c- anus, d- neural tube, e -notochord

Neural tube is the precursor of the central nervous system. Notochord is a flexible rod shaped body found in the chordates and consists of cells derived from mesoderms. Gill slits are the different openings to the gills which lack a single outer cover.
