What molecular evidence supports natural selection? How does this work?

What happens as electrons move along the chain of molecules known as the electron transport chain? they gain energy, which causes atp molecules to lose phosphate groups. they gain energy, which causes h *ions to join with oxygen to produce water. they lose energy, which is then used by the cell to make atp. they lose energy, which is then used to break down atp.

What two factors does carrying capacity compare? population size and resource use population growth and resource availability resource use and time population size and time

Why is it impossible for exponential growth to continue forever?
