Open-pit mining creates a large hole in the ground after minerals are removed from the surface. Which statement best describes an environmental consequence of this process? Heavy metals are released into surrounding soil, poisoning local vegetation.

High salinity of wastewater reduces soil fertility and growth of vegetation.

Billions of gallons of water are pulled from surrounding ecosystems.

Wastewater is contaminated with oil and becomes sludge in landfills.

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.
