Diffuse modulatory synapses or neuromodulation function different than simple point-to point synapses.
1. Number of postsynaptic neurons
In neuromodulation neuron uses one or more neurotransmitter to regulate several neurons. In Synaptic point-to-point transmission only one particular neuron receives signal from the presynaptic neuron.
2. Neurotransmitter sin neuromodulation (neuromodulators) are not reabsorbed broken down by the pre-synaptic neuron like those in classic synapse. Neuromodulators stay in cerebrospinal fluid.
3. Receptors are also different: the receptors for the neuromodulators are typically G-protein coupled receptors while in classical chemical neurotransmission, they are ligand-gated ion channels.
4. Neuromodulation is a slow process, while classic synaptic transmission occurs fast.
"B.) profound social and economic changes occurred" because when the industrial revolution happened a lot of how we make stuff was changed, by factories, and because of this new jobs where created. This gave people money and thus social and economic changes happened.
Answer:
i believe it's the first one
Explanation:
I’m guessing friction of the wheels and the floor help stop it, or the friction of the brake and the wheels cause the wheel to stop moving thus stopping the bike
Brake applied->brake stops wheels from turning->wheels and the floor cause friction and stop the bike
I’m probably wrong but trying to help
