There are several types of antigens, including proteins, carbohydrates, lipids, and nucleic acids. Antigens can be found on the surface of pathogens like viruses and bacteria, as well as on the surface of foreign cells or substances that enter the body. They stimulate the immune system to produce antibodies and mount an immune response.
Antigens are respnses to immune responces.
O... O has no antigens, so it has antibodies for both A and B.
You exhibit Active Immunity when cells encounter anitgens and produce antibodies against them.
No, not safely. O blood has H anitgens but HH blood does not. HH blood type can only receive blood from other HH blood types. HH blood is not stored in blood banks. Also HH blood when tested to see if A B or O, tests as O, unless the lab or technician test further to check for H anitgens, something not routinely done.
People with Type O Blood are different than the other 3 major blood types, where as Type O lacks the anitgens on the red blood cell surface. Type O is known as the Universal Donor due to the fact that type O can give blood to all blood types but can not recieve any blood from the other blood types, only itself the type O.

Well, you first get infected from a scratch or bite, then the infection spreads into the bloodstream, getting by the first line of defence. The second line of defence, would be the white blood cells. They try overcome or "swallow" the infection. the third line of defense, is the anitgens. If all else fails, your f*cked.
When small molecules bind to self cell-surface proteins, they can act as signaling molecules that trigger specific responses within the cell. This binding can also affect cell-cell interactions, influence cell adhesion, or regulate processes like growth and development.
fire types and grass types and flying types can and bug types can and dragon types can and poison types can and steel types can
Integer types, floating point types, Boolean types, character types, string types, pointer and array types, reference types, enumeration and other user-defined types.
Rock-Type moves are weak against Fighting-Types, Ground-Types, and Steel-Types. Rock-Type Pokémon are weak against Water-Types, Grass-Types, Fighting-Types, Ground-Types, and Steel-Types.
Bug-Types are strong against Psychic-Types, Dark-Types, and Grass-Types.
