What three characteristics do all choridates share?
All chordates share three main characteristics: a dorsal hollow nerve cord, a notochord, and pharyngeal slits or pouches at some stage in their development.
All chordates have dorsal tubular nerve cords?
True. All chordates have a dorsal tubular nerve cord, which is a defining characteristic of this phylum.
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.
Do pharyngeal slits disappear before birth in all chordates?
No, pharyngeal slits do not disappear before birth in all chordates. In some chordates, such as fish, these slits persist throughout their life and play a role in respiration and feeding. In other chordates, such as mammals, the pharyngeal slits do not persist through adulthood but are present during embryonic development.
Difference between chordates and vertebrates?
humans are vertebrates as hey have the vertebral column(to be more specific the notochord). u can feel your vertebral column by placing your hand on your back.the bony structure that seems to divide your back into two equal halves is nothing but your vertebral column.
What is three things all chordates have in common besides a back bone what do all chordates have in common beside a backbone?

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).
Do all chordates have fins?
Not all chordates have fins. While many aquatic chordates, such as fish, possess fins for swimming, other groups, like mammals (including humans) and birds, do not have fins. Instead, these animals have evolved different structures for locomotion, such as limbs for walking or wings for flying. Thus, fins are characteristic of certain chordate lineages but not a universal feature of all chordates.
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.
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 is a characteristic shared by all chordates the phylum in which humans are classified?
All chordates are deuterostomes, meaning that in all chordates, the anus develops first during embryological development. All chordates are bilaterally symmetric. Most chordates have a complete digestive tract, and a body cavity. Note: not all chordates have these features, but it is believed that their absence in some chordates is secondary. All chordates are of course animals and eukaryotes.
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 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 will have (in some stage of their life) adorsal, hollow nerve corda flexible, rodlike, internal supporting structure called a notochordpaired gill slits in the throat region
What do all Chordates have?
a backbone
Do all chordates have jaws and limbs?
Well, no they don't... There's a group of chordates called Agnatha which basically contains all the jawless chordates. And there are obviously limbless chordates present, the fishes and the snakes being the most well-known of the examples...
