3 Layers of protein and a polysaccharide called chitin
4 Several kinds of lipids

Explanation:
Chitinous exoskeleton is a unique character of arthropods. Open circulatory system is present in molluscs, echinoderms and hemichordates also. We (humans) also have jointed legs and arms. Metameric segmentation is also seen in annelids and chordates.
