Answer:
The correct answer is chemical energy from broken bonds is transformed into mechanical energy.
Explanation:
Muscle contraction need energy in form of ATP.ATP contain 2 high energized phosphoanhydride bonds.
The hydrolysis of phosphoanhydride bonds releases chemical energy which is transformed into mechanical energy for helping the muscles to move.
Mutation is the only evolutionary mechanism that does little to change allele frequencies.
