They're built from scripts, that have some function. From there, you assgin audio clips, animation clips, and/or textures, references to other files, scripts or data, values (like health, speed, damage-per-hit).
The assignment is stored in meta-data stored in the project, often alongside the script itself, or as part of a prefab. If you just copy the script file to some other project, it'll show all blanks or default values.
