Apolymer contains monomers linked by

A polymer is formed by linking of many monomers units by different kinds of bonds. In carbohydrates, this bond is a glycosidic bond. In the case of proteins, it is a peptide bond. In nucleic acids, the bond is an ester linkage. The monomers link together by two mechanisms: addition polymerization, or condensation polymerization. 

Stored water - gravitational energy

Water fall - kinetic energy

Turbine - kinetic energy

Powerlines - electric energy

Explanation:

Dams are used to store or hold water for hydroelectric power plants. This stored water which has gravitational energy is a form of potential energy.

When the water is left to fall and run fast through the turbine, the gravitational energy is transformed into kinetic energy which makes the turbine to spin.

As the turbine spins, kinetic energy that is produced also powers the shaft of the engine in the electric generator, which produces electricuty.

Kinetic energy is transformed to electric energy and transmitted along powerlines.

*See attachment below for labelled energy that is being transformed at several points.
