25 POINTS PLEASE HELPSelect the correct answer from each drop-down menu. Among cattle, having horns is a recessive trait. Cattle without horns, which are called polled cattle, are common. Suppose a horned male mated with a polled female. Their offspring are all polled. On maturity, two cattle of the F1 generation mated. Their offspring are a mix of polled and horned cattle. (the drop box options are pp, PP, Pp) same options for both. Thanks

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.
