Aparticular species of sea bird underwent a genetic mutation that resulted in big beaks.  the larger size of beaks the bird to break open clams and other mollusks for food.  it also them defend themselves against predators.  after many generations, almost all of the organisms in the population have big beaks.  for which two reasons did this phenomenon occur?

How does the fermentation of pyruvic acid in cells contribute to the formation of atp? a. it completes the oxidation of glucose to co2, creating atp. b. it generates lactic acid, which cycles back through the krebs cycle, producing 2 atp molecules. c. it converts fadh2 to phosphate, which bonds with adp. d. it produces 2 nad+ molecules, which cycle back to fuel the glycolysis reaction, allowing 2 atp molecules to be produced.
