The surface of earth is a thin, solid crust enclosing a molten core of lava. when the core moves, it disturbs the crust at specific locations, which causes earthquakes. how is an earthquake felt on the crust?
a) an explosion that ruptures earth’s surface
b) up-down or sideways wave-like shaking motion
c) the widening of large cracks or fissures over the years
d) a bulging of the ground that takes place over a few days

How do high-energy electrons from glycolysis and the krebs cycle contribute to the formation of atp from adp in the electron transport chain? a. high-energy electrons interact with pyruvic acid to create a phosphate bond with adp, forming atp. b. high-energy electrons supply the needed energy to synthesize atp from the lower-energy adp in the electron transport chain. c. high-energy electrons supply a negative charge which causes the citric acid to oxidize, forming a phosphate group to bond with adp. d. high-energy electrons increase the temperature of adp so it easily reacts to form atp.
