Arthropods have exoskeletons made of chitin. However, chitin is not a protein. It is actually a derivative of glucose, which is a carbohydrate.
Earthworms decompose dead organisms
Insecta (the insects) are the only invertebrates to have flight capability, found under subphylum Hexapoda below the arthropods (phylum Arthropoda). Winged insects are under subclass Pterygota.
mucin
The covering tissue found on a leaf is called the epidermis, while the covering tissue found on your skin is called the epidermis as well. Both serve as protective layers to help regulate exchange of gases, prevent water loss, and provide a barrier against pathogens.
A stiff outer covering is often referred to as an exoskeleton, which is a rigid external covering found in some animal species, such as insects and crustaceans. This protective structure provides support, protection, and attachment points for muscles.
arthropods.
Yes, chitin is a polysaccharide found in the exoskeletons of arthropods and cell walls of fungi. It is not a protein.

No, neurotransmitters are not found in the myelin sheath. The myelin sheath is a protective covering that surrounds nerve fibers, while neurotransmitters are chemical messengers that transmit signals between neurons.
Yes. Lipids are found in the protective coating of the cell membrane of cells. They are also used to store chemical energy, as we synthesize fat polymers from fatty acids / triglycerides.
Chitin is found in the exoskeletons of arthropods and the cell walls of fungus.
Chipmunks, like all mammals, have an endoskeleton, which means their bones are internal. An exoskeleton is a hard outer covering found in arthropods like insects and crustaceans. Chipmunks do not have an exoskeleton.
No, not all. Remember some arthropods are aquatic; the spiracle/trachea/tracheole system utilized by terrestrial insects is largely replaced by gills in marine arthropods.
