Is ant chordate or non-chordate?
Ants and all other insects are non-chordates. Insects belong to the subphylum arthropoda. Animals that are vertebrates are considered to be chordates.
how do lower chordates survive on their adaptive features?
echinoderms, cnidaria and other forms
Can chordates not have a notochord and still be what they are?
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.
Identify one similarity and one difference between vertebrates and other chordates?
They both have a notochord but a chordata does not have a back bone and the vertebrate does
Which one of the following five is least like the other four A Celery b Lettuce cOnion dGrape eAsparagus?
um. grapes
Which of the following was used to filter feeding in primitive chordates and has adapted to other functions in more highly evolved organisms?
Pharyngeal slits
Are vertebrates the largest group among the chordates?
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.

What elements are least likely to react with other element?
Nobel gasses.
Is hydrogen argon sodium nitrogen oxygen or clorine least likely to react with other elements?
Argon is the least likely in the list to react with other elements, because argon is a noble gas and none of the other elements in the list is.
Which type of animals are close to chordates from evolutionary point of view?
Chordates are the common ancestors of fish and sharks. They include lampreys and other types of primitive fish species that live in the sea.

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.
Why can chordates grow larger than any other animal?
I believe it is because they have no actual bones.
Which elemetns are least likely to react with other elements?
These are the so-called noble gases.
Do pelicans belong to the phylum Chordata?
Yes. As Chordates (or members of the phylum Chordata), pelicans share the following characteristics:dorsal nerve cord which is a bundle of nerve fibres which runs down the back. It connects the brain with the lateral muscles and other organs.notochord which is a cartilaginous rod running underneath, and supporting, the nerve cord - in the case of the pelican, a spine.post-anal tail - an extension of the body past the anal opening. (This feature is not always present in some adult Chordates such as frogs and humans, but it is present in the pelican.)Pharyngeal pouches - Chordates, at some stage of their life, have pharyngeal grooves and pouches that develop into other essential parts of their anatomy.
Is a white tail deer chordata?
Yes. As Chordates (or members of the phylum Chordata), deer share the following characteristics:dorsal nerve cord which is a bundle of nerve fibres which runs down the back. It connects the brain with the lateral muscles and other organs.notochord which is a cartilaginous rod running underneath, and supporting, the nerve cord - in the case of the deer, a spine.post-anal tail - an extension of the body past the anal opening.
