Answer: it is difficult because it is necessary to understand some concepts used in a system. For example what is a boundary, and environment which can be positive or negative, etc. A sample could be the course OpenLearn that provides an example of Computing & IT.

Although cells are diverse, all cells have certain parts in common. The parts include a plasma membrane, cytoplasm, ribosomes, and DNA. The plasma membrane (also called the cell membrane) is a thin coat of lipids that surrounds a cell.
Hope it helps ^^
I believe that hybrid zones provide an opportunity to investigate the evolution of reproductive isolation.Hybrid zones are areas where hybrid offspring of two divergent taxa are prevalent and there is a line in the genetic composition of populations from one taxon to the other. A hybrid zone allows researchers to see what happens when closely related species come together. Reproductive barriers may be strengthened or weakened, depending on environmental and genetic factors.
