The ability of recipient T cells to recognize donor-derived antigens, called allorecognition, initiates allograft rejection. Once recipient T cells become activated, they undergo clonal expansion, differentiate into effector cells, and migrate into the graft where they promote tissue destruction.
You need to test the hypothesis several times and record all results. Once you obtain the same results several times, I think that means its a theory
Air moves from the alveoli to the blood after being inhaled into the lungs. The alveoli get oxygen to the blood and then the carbon dioxide moves from the blood to the alveoli, so it can be released when you exhale. :)

Answer:
<u>Cilia</u>
Explanation:
Cilia and flagellum are made up of microtubules.
Cytoskeletal filaments are structures which allow movement. In cilia and flagella, the cytoskeletal filaments are present in the form of microtubules and the primary work of these structures is to facilitate in movement.
Cilia is also present in mammals to facilitate the movement of fluids in cells.
Structurally, there is no difference between cilia and flagella. The only difference between cilia and flagella is in their lengths.
