An experiment was designed to test the effect of a chemical called NMN in mice. An equal number of male and female
mice were tested and a large sample size was used. Male mice
were fed twice daily and female mice were fed once daily.
Male mice were given 100mg of NMN and female mice were
given 25mg of NMN. Male mice were given NMN for 30 days
and so were female mice. Mice that were not given the drug
were also monitored as a control. Name two positives of the
experiment and two negatives of the experiment:

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.
