Split and merge into it. Answer by Anamarasigan. Confidence votes 164. There are three kinds of chemical messengers in the nervous system: Neurotransmitters, endorphins and hormones. 1) Neurotransmitters are released by transmitting neurons.They alter the activity of the receiving neurons. Note that neurotransmitters exist outside of the nervous system as well. believe they are called chemical messengers because of their function and the fact it is a chemical. They travel through the blood and target cells respond to hormones often â¦ because of their structure.
A tsunami is a very long-wavelength wave of water that is generated by sudden displacement of the seafloor or disruption of any body of standing water. Tsunami are sometimes called seismic sea waves, although they can be generated by mechanisms other than earthquakes. tsunami is a very long-wavelength wave of water that is generated by sudden displacement of the seafloor or disruption of any body of standing water.

A tsunami is a huge wave, usually caused by volcanic or earthquake activity under the ocean, which can eventually crash onto the shoreline. The effects on a community can be devastating. What causes a tsunami? When an earthquake, volcano or landslide happens on the ocean floor, water is displaced. This water forms the start of the tsunami. When the waves reach shallower water: their height can increase by several metres; the shallow water slows the wave; the waves get closer together; It is hard to see that a tsunami is approaching. The most obvious sign is the coastal water retreats just before the waves reach the shore. This is actually the trough of the wave following behind.
