can someone help me turn this into an if then statement for my lab??? i am really stuck and can include more info about the lab if needed. statement- i think the unknown skull looks most like Australopithecus afarensis (extinct hominid) because of how long the skull is and the skinny shape/cheekbones thanks!

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.
