What did you say about the cats in your room haha
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.
Answer:
Since the origin of humans on this planet, they have been trying their best to make their lives easier on this planet. In doing so, human activities have some how heavily damaged the Earth. Many day to day activities of humans are dangerous for the Earth.
Some of the consequences of human activities on the Earth's fresh water are :
Extinction of many aquatic species:
The water consumed by humans comes from the fresh water oceans. As the population of humans is increasing enormously, the water from the oceans is being consumed at dangerous levels. This has caused many species of aquatic animals to become extinct or to be at a verge of extinction as they do not have a habitat to survive or reproduce.
Pollution:
Many heavy industries, house sewage, farmers dispose waste into the fresh water. Hence, killing aquatic animals and polluting the fresh water ecosystems.
