Chordates are animals that comprise the vertebrates. The three structures that are present during their development are the notochord, a tubular nerve cord and gill slits leading into the pharynx.

∙ 13y agoAll the chordates have three basic characters
1. A Dorsal tubular nerve cord
2. Pharyngeal Gill Slits (In lower chordates these are permanent/temporary in their life but in higher chordates these are seen during embryonic conditions)
3. A Notochord (In lower chordates these are permanent/temporary in their life but in higher chordates this is seen in embryonic conditions)

Wrong. Synap is 3 of chordates: Notochord, postanal tail, dorsal hollow nerve cord.

What is correct about homologous structures?
All insects have some very distinct structures in common. First is bilateral symmetry and three pairs of legs attached to a body with three major parts, the head, thorax and abdomen. All insects have exoskeletons and an open respiratory system as well.
All chordates have dorsal tubular nerve cords?
no
Which of the following structures is common to all nerve cells?
dendritesaxonSchwann cellscell body
Do pharyngeal slits disappear before birth in all chordates?
yes or no
What is a trait that is ancestral to all chordates?
A vertebral column. (a back bone)
What is three things all chordates have in common besides a back bone what do all chordates have in common beside a backbone?
All Chordates have(in part of their life or another) A Notochord A hollow dorsal nerve cord A post-anal tail
What is a chordate and what do all chordates have in common?
Chordates are that group of animals having some form of a spinal column (which include the vertebrates).
All vertebrates are chordates but not all chordates are vertebrates?
all vertebrates are chordates because vertebrates are the sub- group of phylum chordates and also it follow one of the important feature of the chordates i.e. presence of notochord whereas all chordates are not vertebrates because some chordates are cephalochordates, urochordates.
Do chordates have a coelom?
Yes. All chordates are coelomates.
What is the popular name for chordates?
There isn't a "popular name" for them. The most familiar chordates are the vertebrates, but not all chordates are vertebrates (tunicates, for example, are chordates).
The three things all chordates have?
Chordates all possess a notochord (dorsal supporting rod), gill slits, and a dorsal nerve cord some time in their life cycles.
What are the three structures that all chrdates have in common?
Urochordata, represented by tunicates; Cephalochordata, represented by lancelets; and Craniata, which includes Vertebrata.
What three characteristics do all chordates share?
All chordates have a dorsal, hollow nerve cord, a flexible, rodlike, internal supporting structure called a notochord, and paired gill slits in the throat region at some point in their lives.
What is a characteristic shared by all chordates the phylum in which humans are classified?
One characteristic shared by all chordates is the presence of a notochord, a flexible rod that provides structural support. Humans, being classified under the phylum Chordata, possess a notochord during their embryonic development that eventually develops into the spinal column.
What runs down the back of all chordates?
nerve cord runs down the back of ALL chordates
Are all fish chordates?
All fish are chordates. Chordates are vertebrates that have a hollow dorsal nerve called a notochord. They also have a central nervous system and gill clefts.
What do all Chordates have?
a backbone
