The partial substitutability of sucrose and wheel running in experiments by Belke and colleagues (2006) reflects:
A) The initiation and maintenance of travel or locomotion induced by loss of body weight and energy stores
B) The termination of travel or locomotion as food supply increases
C) The increased value of wheel running as food availability increases
D) Both a and b

The partial substitutability of sucrose and wheel running in the experiments indicates both the initiation and maintenance of travel or locomotion due to loss of body weight and energy stores (A), and the termination of travel or locomotion as food supply increases (B). This reflects an adaptive behavior where the value of physical activity (wheel running) can substitute for food rewards under certain conditions, showing how both factors can influence behavior in a complementary manner.
