B. Circuits that signal other circuits
C. Circuits that control other circuits
D. Communication Circuits

Answer 1

Cells communicate through stages of reception, signal transduction, and cellular response in signaling processes, which can operate over various distances.

Step-by-step explanation:

Cells communicate with each other through various signaling processes. In this signaling process, the stages include:

• Reception: where the signaling molecule, or ligand, encounters the target cell and binds to a receptor, initiating the signal (between A and B).
• Signal Transduction: the process where the signal is relayed within the target cell (between B and C, C and D).
• Cellular Response: the final stage where the cell responds to the signal by performing a certain action, like converting glycogen to glucose (between E and A).

Signaling mechanisms can operate over short or long distances, such as neurotransmitters transmitting signals over a synapse or hormones traveling through the bloodstream to reach distant organs.
