if a tissues blood supply is cut off for a time and then restored, it often exhibits reactive □, a higher than normal level of blood flow.

Explanation:

The question is about a biological process related to blood flow in tissues. When a tissue's blood supply is temporarily cut off and then restored, the phenomenon of increased blood flow afterward is known as reactive hyperemia. Hyperemia refers to an increased blood flow to a tissue, and reactive hyperemia specifically occurs as a response to the previous ischemia (lack of blood supply).

Answer:

hyperemia
