Human stem cells are totipotent, meaning that they can differentiate into any cell type. Their use to produce healthy tissue to replace damaged tissue is called .

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.

yes!

explanation:

because it has a type of fat that can make you extremely sick

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex
