water stored in the spaces between rocks inside earth that is found within a few miles of the earths surface

Groundwater is fresh water (from rain or melting ice and snow) that soaks into the soil and is stored in the tiny spaces (pores) between rocks and particles of soil. Groundwater accounts for nearly 95 percent of the nation’s fresh water resources. It can stay underground for hundreds of thousands of years, or it can come to the surface and help fill rivers, streams, lakes, ponds, and wetlands. Groundwater can also come to the surface as a spring or be pumped from a well. Both of these are common ways we get groundwater to drink. About 50 percent of our municipal, domestic, and agricultural water supply is groundwater

RNA

Explanation: Nucleic acid can be defined as the biopolymers  which is known to be the most essential for all the life forms on the earth.

Nucleotides that are present in the nucleic acid are the monomers that is made up of 5 carbon sugar, nitogenous base, phosphate group.

If the sugar is ribose sugar then it is known as Ribonucleic acid. They are found in all the living components as the genetic material that transfers the information from parents to their children.
