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.
It is because that's a place where no one lives so they're safe.
Answer:
respiratory system
Explanation:
The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
<span>in an environment where there is little or no oxygen. aerobic respiration requires oxygen ad when it is not present fermentaion (anaerobic respiration) occurs because it works when oxygen isn't there</span>
Needle like leaves are protective by nature. They are protective to the branches because they deter animals from eating the leaves. This helps the plant/tree stay alive.
