Pathogen is kinda disease, virus, bacteria or other microorganisms ( which can cause disease)
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.
<h2>Evolution </h2>
Explanation:
A bottleneck genetic drift and micro-evolution have occurred in the given condition
- In bottleneck effect, inferior genotype is eliminated from a homogeneous gene pool due to strong natural selection pressure and changing environmental conditions and this leads to genetic drift as a result only a few most adapted genotype survives and flourish
- Micro-evolution is a type of evolution in which formation of new species occurs at a slow pace following phyletic gradualism
- Causes of micro-evolution are point mutation and recombination
