Answer 1

The animal kingdom can be divided into two main groups – vertebrates (animals with a backbone) and invertebrates (animals without a backbone).

Answer 2

The animal kingdom is divided into vertebrates and invertebrates

Step-by-step explanation:

Invertebrate animals are those that have no internal skeleton, bone or cartilaginous. They are generally small animals. Examples: arachnids, insects, earthworms.

While vertebrate animals have a bone skeleton or cartilaginous bones. The skeleton is formed by the spine to which the different bones of the skeleton articulate. Examples: birds, fish, reptiles.

The main characteristic that all animals share is that they are multicellular organisms, which are organized and each one has its specific function. These cells have a nucleus and have no cell wall.
