The bone structures in the image below
show similarities in development between
limbs. How does this evidence support the
theory of evolution?
It provides evidence that the organisms can share
common ancestry
It shows that the organisms have a similar genetic
composition
It supports the idea that the organisms lived in the
same location
It can be used to predict how old the organisms are
Frog
(amphibian)
Alligator
(reptile)
Chicken
(bird)
Horse

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

answer; i believe that the correct answer is (lung);

sorry, is there a picture? i do not see any arrows.
