One of the following is not a characteristic of all chordates:

(A) backbone

(B) bilateral symmetry

(C) dorsal nerve cord

(D) notochord

A

Explanation:

some chordates have a backbone but not all of them

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

to this one it would be receptive field
