Which of the following best explains why some species are able to survive major changes in the environment? A
Some species have variation within their phenotypes, giving individuals an advantage for surviving change.

B
Some species are able to reproduce at a fast rate, creating large populations that ensure some individuals will survive.

C
Some species have identical genotypes, making them immune to change in the environment.

D
Some species are genetically similar, ensuring that they will reproduce offspring that will not change traits.

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.
