what is Benedict's solution and orange-red precipitate
three differences between aerobic and anaerobic respiration
what are aerobic requires oxygen; anaerobic does not; aerobic occurs in the mitochondria while anaerobic occurs in the cytoplasm; aerobic produces more energy from the same amt. of substrate than anaerobic
this type of organism causes disease in its host
