Answer 1

Answer:

First Question:-

Invertebrates are animals that don’t have a backbone. The vertebral column is another name for the backbone. Over 90% of all species on Earth are invertebrates, and invertebrate species have been found in the fossil record as far back as 600 million years ago. Molecular biology studies suggest that all invertebrates evolved from a single invertebrate group.

Second Question:-

Although the vertebral column is perhaps the most obvious feature in vertebrates, it was not present in the first ones, which probably had only a notochord (flexible rodlike structure which plays a role in the development of the nervous system). The vertebrate has a distinct head, with a differentiated brain and three pairs of sense organs (nasal, optic, and otic [hearing]). The body is divided into trunk and tail regions.

Third Question:-

A vertebrate is an animal with a spinal cord surrounded by cartilage or bone. The word comes from vertebrae, the bones that make up the spine. Animals that are not vertebrates are called invertebrates. Vertebrates include birds, fish, amphibians, reptiles, and mammals.

Forth Question:-

Invertebrates are animals that neither possess nor develop a vertebral column, derived from the notochord. These include all animals apart from the subphylum Vertebrata. Invertebrates are animals with no backbone. More than 90% of the animals are invertebrates among the estimated 15-30 million animal species.
