All living organisms are made up of cells. Cells are the basic units of life. In complex living organisms, cells are organized into tissues, tissues are organized into organs, and organs are organized into organ systems. What characteristic of life does this information represent?
A.
Life is composed of only complex organisms.
B.
Life can be arranged in a structural hierarchy.
C.
Life does not demonstrate order in its systems.
D.
Life tends to be chaotic and random.

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.

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes
