Answer 1

Answer:

no, its a fact that mice, turtles and snakes all have backbones.

And earthworms , butterflies and lobsters dont have backbone

Answer 2

Because mice, turtles, and snakes all have backbones earthworms, vertebrates, butterflies, and lobsters don't have a backbone, invertebrates do.

What is the difference between vertebrates and invertebrates?

As opposed to cartilaginous or bony vertebrates, invertebrates are any animal without a vertebral column or backbone.

Invertebrates butterflies and lobsters have an exoskeleton instead of a backbone and internal skeleton, they have a circulatory system that is open.

Vertebrates, on the other hand, lack an exoskeleton but do have a backbone and an internal skeleton, their circulatory system is closed.

Therefore, Jack grouping invertebrates lack a backbone whereas vertebrates have one, which is the phrase that best sums up both groups of animals.
