What are the two types of anaerobic respiration? Describe the two in one paragraph.

alcoholic fermentation and lactic acid fermentation I'm pretty sure

Explanation:

alcoholic fermentation is when yeast turns sugars into ethanol

lactic acid fermentation is when our muscle cells deal with pyruvate during anaerobic respiration

hopefully this helped :)

carbon atoms, hydrogen, oxygen, and nitrogen.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
