Question

Which if the following best describes why invertebrates isn’t considered a scientifically valid word when classifying animals

Answer 1

I believe the answer is b.

Step-by-step explanation:

All invertibrates share one charistic in common, they have no backbone.

Answer 2

The correct answer is option D.

Explanation:

Invertebrates don’t have a common similarity in an anatomical structure that all have. They are different in their structure so they should not be grouped into one group.

All different groups of invertebrates have a different type of symmetry, composition, and anatomically different but there is not a common character except the fact that no one has vertebra.

Thus, the correct answer is option D.
