The overuse of antibiotics has led to a) the extinction of viruses. b) the extinction of bacteria. c) new antibiotic-resistant populations of viruses. d) new antibiotic-resistant populations of bacteria.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

b. lithosphere, asthenosphere, mesosphere   is the answer most likely
