(Science: cell biology) A protein subunit in which the polypeptide chain is exposed on both sides of the membrane. The term does not apply when different subunits of protein complex are exposed at opposite surfaces. most integral membrane proteins are also transmembrane proteins.Please contribute to this project, if you have more information about this term feel free to edit this page.he term does not apply when different subunits of protein complex are exposed at opposite surfaces. most integral membrane proteins are also transmembrane proteins.

The level of complexity refers to the duties, the degree of autonomy and the scope of responsibilities. The assessment of the level of complexity is based on the position and not on the incumbent. There are generally three levels of complexity: the entry and learning level, the independent level, and the team leader or specialist level.1.
In the simplest scheme, the first trophic level (level 1) is plants, then herbivores (level 2), and then carnivores (level 3). The trophic level is equal to one more than the chain length, which is the number of links connecting to the base.The base of the food chain (primary producers or detritivores) is set at zero.n the simplest scheme, the first trophic level (level 1) is plants, then herbivores (level 2), and then carnivores (level 3).
