As a ship is unloaded, why does it rise higher in the water? a. the density of the ship and its cargo increases. b. the mass of the ship and its cargo increases. c. the density of the ship and its cargo decreases. d. the buoyancy of the ship and its cargo decreases. this is science i need

Because the bouyancy of something also depends on it's weight (mass).

When you unload a ship, less gravity is applied to it (gravity pulls things down), so that is why it rises.

B

d. the weight of the book

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.
