Answer 1

The correct answer is -

growth takes place through ecdysis

a rigid exoskeleton made of chitin

jointed appendages

segments specialized into functional tagmata

Step-by-step explanation:

Arthropods are the largest phyla of the animal kingdom and comprise 80 % of the total animals known. It includes crabs, lobsters, insects, and many other invertebrates. The key features of this phylum make them special and unique to other groups.

These organisms show growth through molten and ecdysis which is the removal of old skin with growth. These organisms have an open circulatory system and the outer layer is made up of chitin that provides a tough exoskeleton. Arthropods have jointed appendages instead of branched or single body. These segments are fused togather and these functional fused segments called tagmata.
