The seismic dampers are mechanical devices that have the purpose to dissipate the kinetic energy from the seismic waves that are penetrating the structure of a building.
They are very import since they started to be used because they are able to minimize the damage to the buildings and avoid their destruction to a certain degree, depending of course on the strength of the seismic waves.
Before they were used, an earthquake that was not very strong was able to make huge damage on the buildings, and very often to totally destroy them. Since the introduction of the seismic dampers though, the buildings are able to withstand much bigger earthquakes without being damaged, which saves millions of lives every year, and also a lot of material damage is avoided.

<u>Answer:</u>
The characteristic that is common to "all three groups of reptiles" is that they are all ectotherms.
<u>Explanation:</u>
- Almost all the reptiles are referred to as 'ectotherms' because they are all cold-blooded.
- They adjust their body temperature according to the temperature of the surrounding.
- Reptiles like snakes do not have claws or eyelids. Moreover, not all reptiles protect their eggs.
- The "sea turtles" lay eggs on the seashores and go back to the seas.
- Thus, the only common characteristic among all the reptiles is that they are all ectotherms.
