| Which level of control operates at the cell level, often using genes and enzymes to regulate cell function? | intracellular regulation |
| Events that lead to an immune response to an infection or the formation of a blood clot are examples of | positive feedback. |
| Because negative feedback control systems oppose changes that are opposite in direction to the initial disturbance, they are | slowed or maintained in the homeostatic range. |
| Many complex processes of the body are coordinated at many levels. These include | intracellular. intrinsic. extrinsic. |
| The concept that information may flow ahead to another process to trigger a change in anticipation of an event that will follow is called | feed-forward. |
