In Earthquake testing, the engineers are using the world largest shake tables to test new construction methods for buildings in the areas prone to the earthquake.
<u>Explanation:</u>
They believed that they have the devised a system to build the taller wood-frame buildings that can still safely withstand even very powerful tremors. To withstand the collapse, the buildings need to redistribute the forces that travel through them during a seismic event.
Shear wells, cross braces, diaphragm, and moment-resisting frame are the central reinforcing the building. Shear wells are the technology of the useful building. That helpful to transfer the earthquake forces.
The production of these crops is centered in the eastern third of the state but there are notable concentrations elsewhere, particularly in the river valleys of the Arkansas River (central Arkansas) and the Red River (southwest Arkansas).
The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as nucleus, ribosomes and mitochondria which are crucial for protein synthesis, assembly and repair. In other words they lack both the information and the machinery for making or repair of proteins.
Due to lack of DNA and cell organelles, red blood cells cannot be able satisfy the central dogma which summarizes synthesis of proteins as DNA → RNA → proteins.
DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes in the cytoplasm, then translating or decoding this information, which results in the making of protein.
