What does verte brate and in verte brate mean?

Answer 1

"Vertebrate" refers to animals that have a backbone or spinal column, including groups like mammals, birds, reptiles, amphibians, and fish. In contrast, "invertebrate" describes animals that lack a backbone, which includes a vast array of organisms such as insects, arachnids, mollusks, and crustaceans. Together, these terms categorize the animal kingdom based on the presence or absence of a vertebral column.
