Vertebrates
The four specific characteristics of chordates are that they have a notochord, hollow nerve cord near the notochord, pharyngeal pouches, and an endostyle. Many of these characteristics disappear in invertebrate chordates when they reach adulthood. Most vertebrate chordates retain all four features, such as humans.
They are actually true chordates, however they are some of the simplest chordates.
Chordates are a group of animals which include vertebrates (animals having a spinal column), so yes, birds are chordates.
chordates have spinal cord and it separates it from the animals which do not have spinal cord
Vertebrates
They don't have a backbone and have all the characteristics of a chordate.
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.
The presence of a notochord at some point in the organism's development is one of the characteristics that distinguishes chordates from other phyla. Without it, I'm not sure if the organism would be considered a chordate.
a hollow nerve cord, a notochord, pharyngeal pouches, and a postanal tail
The following are characteristics of Gregorio chants except:
Yes, one of the key characteristics of chordates is that they have a post anal tail, including during fetal development.

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.
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).
Chordates are not vertebrates because although some vertebrates are chordates theres many reasons why chordates arent vertebrates.the first reason is because chordates consist of a notochord or a dorsal nerve.
