Khamala floats a note across a river to Oleg instead of directly passing it from her hand to Oleg's hand. If, in this scenario, the river represents the synapse, which component of the scenario represents the axon?

Answer: Khamala

Explanation:

A synapse is the space between neurons across which neurotransmitter diffuses between cells to allow chemical communication. If the river is the synapse, then Khamala is the axon because axon is a physical structure that carries signals away from the cell body towards post-synaptic cells.
