Microbes have played a significant role in the advances of the last century, such as for cutting dna and to better understand the microbes that live on and in our bodies.

Restriction enzymes and genome sequencing.

Explanation:

Microbes include all the microscopic organisms that cannot be seen by the naked eye. The microbes can be harmful or beneficial for the living organisms and can be used in medication as well.

The microbes has provided molecular tools and different techniques have been designed to study them. The restriction enzymes also known as molecular scissors used to cut the DNA and further modification of the DNA. The genome sequencing is done to sequence the genomic DNA of the organisms and there used in the medicine.

Thus, the answer is restriction enzymes and genome sequencing.

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.
