Answer:
<h2><em><u>Base</u></em><em><u> </u></em><em><u>isolated</u></em><em><u> </u></em><em><u>system</u></em></h2>
Explanation:
<u>Fixed based system:- </u>
A fixed-base building (built directly on the ground) will move with an earthquake’s motion and can sustain extensive damage as a result.
<u>Base isolated system:-</u>
A base isolation system is a method of seismic protection where the structure (superstructure) is separated from the base (foundation or substructure).
<em><u>Hence</u></em><em><u>,</u></em>

Answer:
Cation-exchange capacity is a measure of how many cations can be retained on soil particle surfaces. Negative charges on the surfaces of soil particles bind positively-charged atoms or molecules, but allow these to exchange with other positively charged particles in the surrounding soil water
Food is the most important source of chemical energy for living things. The chemical energy in food is converted, or changed, by the body into moving mechanical energy and heat energy. People have invented ways to use the chemical energy of substances to power machines.
