Final answer:
The ranking of the signaling based on distance traveled is as follows: neuronal signaling, endocrine signaling, paracrine signaling, and contact-dependent signaling.
Step-by-step explanation:
The ranking of the signaling based on distance traveled is as follows:
- Neuronal signaling: Neuronal signaling can travel long distances through the nervous system to reach the target cell.
- Endocrine signaling: Endocrine signaling uses the circulatory system to transport ligands, allowing them to reach distant target cells.
- Paracrine signaling: Paracrine signaling acts on nearby cells and the signal travels a shorter distance compared to neuronal and endocrine signaling.
- Contact-dependent signaling: Contact-dependent signaling involves signaling molecules moving directly between adjacent cells and the distance traveled is the shortest among all the signaling methods.
