Why is biomass a better alternative to coal?
a. can be regrown quickly
b. does not need to be burn
c. does not release carbon dioxide
d. is not radioactive

The correct answer is A. Can be regrown quickly

Explanation:

Biomass is made from the living organic material fro example plants and animals. Biomass is used as an alternative source of energy. Most of the energy which is used to gain energy comes from wood, wood waste, sugarcane, manure, straw.

Biomass is a better alternative of coal because as biomass is made from organic waste it can regrow quickly while as coal is a fossil fuel it takes thousands of years to replenish. So biomass is a renewable source of energy.

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.
