<span>Of these choices, neuronal communication between the brain and the muscles of the leg is best conceptualized as electrical and chemical signaling.
The brain sends signals of the electrical and chemical type to reach the leg and move its muscles. Once these signals get to the muscles of the leg, they are moved into motion as a result of the brain "ordering" the leg to move so that a person could get up or get to another place.

<u>Pressure increases with depth </u>
Explanation:
Pressure increases with depth because the molecules at the deeper end are compressed by the weight of the above column of the fluid. Compression means there are more molecules of the fluid per volume in the deepest place than the surface. More molecules mean more pressure.
This is why divers need special gear when diving deep in the ocean to protect themselves form increased water pressure. In addition, the lowest atmospheric layers have the highest pressure because they are more dense and bear the weight of the above air column. This is why air pressure is a bit lower up the summit of a mountain than at its base.
Answer:
Cellular communication
Explanation:
At the end of a neuron, there is a space called the synaptic junction that helps it communicate with another neuron or organ in order to produce a response. When the impulse reaches the end of a neuron usually called the axon terminal, it causes the opening of voltage gated ion channels that causes the influx of ions inside the cells. This in turn will cause synaptic vessicles that contain neurotransmitters to move towards the membrane of the axon terminal and fuse with the membrane then open up to release the neurotransmitters into the synapse (space between the 2 neurons). When this happens, the voltage gated channels close. The neurotransmitters then bind to ligand receptors on the second recieving neuron that cause it to produce an effect like stimulate an organ or produce an impulse . After using up the neurotransmitters, they can be recycled or broken down into metabolytes that are used up by the cell.
