According to the first and second laws of thermodynamics
A) energy flows spontaneously from systems with high free energy to systems with low free energy in a series of step-by-step transformations.
B) the quantity of energy in the universe is constant but its quality is not.
C) transformation of potential energy in a biological system results in the loss of a small amount of energy.
D) energy can be transformed from one form to another, but can be neither created nor destroyed.
E) energy is lost from systems during energy transformations resulting in increasing entropy in the universe.
