Which characteristic best distinguishes glycolysis and the Krebs cycle from the electron transport chain? the amount of ATP produced
the location in which they occur
whether glucose is broken down
whether they occur in plants or animals

The characteristic best distinguishes glycolysis and the Krebs cycle from the electron transport chain is the amount of ATP produced. In glycolysis net ATP production is 2 ATP and in 1 Kreb's cycle 38 ATP are produced.

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
