How do aerobic and anaerobic respiration compare? a. both aerobic and anaerobic respiration are very efficient and produce a large amount of energy. b. neither anaerobic nor aerobic respiration is very efficient or produces a large amount of energy. c. anaerobic respiration is very efficient and produces a large amount of energy, while aerobic respiration is not very efficient and produces a small amount of energy. d. aerobic respiration is very efficient and produces a large amount of energy, while anaerobic respiration is not very efficient and produces a small amount of energy.

D

Aerobic respiration is more efficient as it causes the complete breakdown of organic molecule(Glucose) into Carbondioxide and water. This results in extraction of large amount of energy which is 38 ATP.

In the contrary anaerobic respiration which occurs during fermentation produces alcohol or lactic acid.It is very less efficient as only 2ATP molecules are produced.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

it depends on how much it could carry.
