The cuticle means outer layer. It can be considered an external envelope as in an insect. Or a fatty waxy film scene in plants. This also in humans accumulates at the base and sides of the fingernail. It's function is to protect.
animalChitin is a polysaccharide that strengthens the structure of arthropod (insect, crustacean, etc.) exoskeletons, as well as cephalopod (squid and octopus) beaks, and fungal cell walls.

Similar structures that have evolved independently are called homologous structures. An example would be the wings of a bird and the wings of an insect.
I am an ANT and my insect name in my name is Steve.
They both perform the function of providing a rigid structure.
Analogous structures are features of two different species that are similar in how the function, but the structure of the two features is different. The wings of an insect and the wings of a bird are analogous structures.
An insect is a type of animal. Any structure on an insect is, by definition, a structure on an animal.
Homologous structures have the internal structure, but different functions. For example the human arm, horse foreleg, bird wing, and whale flipper have similar internal skeletal structure, but different external structure because of their different functions. Analogous structures have similar external structure because of similar functions, but dissimilar internal structure. An example of analogous structures would be the wings of an insect and a bird.
Yes and no, it depends on how you define brain. The insect nervous system has a central ganglion in the head that serves the function of the brain, but it does not have the structure of the brains of "higher" animals.
Because an insect depends on it for survival, I guess.
A solitary insect lives and hunts by itself. I does not have a social structure or a colony of any kind.
No, but they do look similar.
It's not, it is insect
There are many characteristics that are general of insect body structures. Most insect bodies include a hard casing for protection for example.
They are both alive.
They are all cycles of insect growth!
