Answer: It is necessary for the immune system to clearly distinguish foreign cells and proteins from those made by the body so that the immune system will be able to fight foreign cells and proteins and eliminate them from the body.
Explanation: The ability of the immune system to clearly distinguish foreign cells and proteins from those made by the body helps the body to identify pathogens that invade the body and trigger appropriate immune response to eliminate the foreign cells and proteins.
When the immune system of the body fails to distinguish foreign cells and proteins from those made by the body, the body launches an attack against its cells, that is the immune system triggers an autoimmune response in which attacks are launched against the cells of the body and destroy them. This condition in which the immune system recognizes the cells of the body as non-self and launches an attack against them is known as autoimmunity. Autoimmunity is the major cause of most degenerative diseases such as type I diabetes mellitus.

Answer:
Nesting & Foraging behavior
Explanation:
Seabirds are generally tertiary consumers and / or marine predators that, in marine foodwebs, occupy the upper trophic level. They are very well adapted to all marine ecosystems and feed on a variety of prey: from micro-crustaceans to fish and cephalopods.
Generally, seabirds are observed performing a nesting behavior, by laying eggs near the shore, and then are found exhibiting foraging behavior -searching and foraging for prey- in both the coastline and pelagic zone, also known as the open sea.
Seabirds exhibit different foraging behaviors, for example, the <u>surface feeding behavior which involves flying along the surface with their beak in the water. Gulls, albatrosses and petrels are examples of surface feeders.</u>
<u>On the other hand, plunge diving involves preying on fast marine organisms by diving into the water during their flight. Pelicans are example of seabirds who engage in this behavior.</u>
