Yes, chordates have true coeloms. Coeloms are fluid-filled cavities that are completely lined by mesoderm, providing space for internal organs to move and function independently of body wall movement. Chordates, including vertebrates like mammals, birds, reptiles, amphibians, and fish, possess coeloms that are derived from mesoderm during development.
Lancelets are considered true chordates because they possess a notochord, dorsal nerve cord, pharyngeal slits, and a post-anal tail at some stage in their life cycle, which are characteristic features of chordates. They are believed to represent an early evolutionary stage of the chordates.
True. All chordates have a dorsal tubular nerve cord, which is a defining characteristic of this phylum.
Chordates are a group of animals which include vertebrates (animals having a spinal column), so yes, birds are chordates.
Chordates are a diverse group of animals that includes humans, and they are not inherently harmful. While some species of chordates may pose a threat due to factors like venom or aggression, the majority of chordates play important roles in ecosystems and are not harmful to humans.
Lower chordates refer to a group of simple, marine invertebrate animals that belong to the phylum Chordata but do not possess a backbone or vertebral column. Examples of lower chordates include tunicates, lancelets, and hagfish. They are considered primitive chordates with some characteristics of vertebrates.

True. All chordates have a dorsal tubular nerve cord, which is a defining characteristic of this phylum.
True coelom is body cavity lined by mesothelium on both sides as in 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).
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.
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.
Vertebrates are a subgroup of the chordates, meaning that all vertebrates are chordates, but not all chordates are vertebrates. Vertebrates are distinguished from other chordates by having backbones or spinal columns.All vertebrates have muscular systems that mostly consist of paired masses, as well as a central nervous system which is partly located inside the backbone (if one is present). The defining characteristic of a vertebrate is considered the backbone or spinal cord, a brain case, and an internal skeleton, but the latter is not true for lampreys, and the former is arguably present in some other chordates. Rather, all vertebrates are most easily distinguished from all other chordates by having a clearly identifiable head. Sensory organs--especially eyes--are concentrated at the foreend of the body, and there is pronounced cephalization.
Chordates are animals with vertebrates.
Chordates are a group of animals which include vertebrates (animals having a spinal column), so yes, birds are chordates.
Yes, hemichordates are not chordates as they are their own phylum.
Chordates such as the sea squirts and lancelets do not have a backbone that is why they are called vertebrate chordates.
