The correct answer is: In both systems, ATP is produced by chemiosmosis.
Both of the processes, photosynthesis and electron transport chain in mitochondria use chemiosmosis (movement of ions across a semipermeable membrane, down their electrochemical gradient) to produce energy or ATP (via ATP synthase). The movement of hydrogen ions across the thylakoid membrane in order to galvanize the production of ATP is equal to the movement of those ions across the inner mitochondria membrane. Electrons are accepted by NADPH in photosynthesis (but not FADH2 as in mitochondria).

Answer:
Dogs were probably domesticated by accident, when wolves began trailing ancient hunter-gatherers to snack on their garbage. Docile wolves may have been slipped extra food scraps, the theory goes, so they survived better, and passed on their genes. Eventually, these friendly wolves evolved into dogs
Explanation:
Answer:
c. Glycolysis evolved in an oxygen-rich environment.
Explanation:
Glycolysis is the pathway that breaks down glucose into two molecules of pyruvate. It is a common pathway that is performed by both aerobic and anaerobic organisms. In aerobic organisms, glycolysis is followed by Kreb's cycle and electron transport chain. In anaerobic organisms, alcohol or lactic acid fermentation regenerate the NAD+ which is required to sustain glycolysis.
Therefore, glycolysis is independent of oxygen availability and can be performed under both aerobic and anaerobic conditions. This means that the pathway of glycolysis evolved under anaerobic conditions.
