Q2 Which excerpt from "The Raven" makes use of repetition? Not the least obeisance made he, not a minute stopped or stayed he;/ But, with mien of lord or lady,
perched above my chamber door-
Fancy unto fancy, thinking what this ominous bird of yore-/ What this grim, ungainly, ghastly, gaunt, and
ominous bird of yore
Then, methought, the air grew denser, perfumed from an unseen censer/ Swung by Seraphim whose
foot-falls tinkled on the tufted floor
And my soul from out that shadow that lies floating on the floor/ Shall be lifted - nevermore!

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.

the answer is "a.) well–developed vascular system."
