Amino acids are named after two of their functional groups:

A) the amino group (NH2), which acts like a base, and the carboxyl group (COOH), which acts like an acid.
B) Amino acids also contain a third functional group, often called the R group. In alanine, the R group is a methyl group (CH3).
C) In serine, the R group is a methyl alcohol (–CH2OH).

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
