answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).

the answer is definitely 36.

hope this : )
