Why is aerobic respiration more beneficial than anaerobic respiration?

Ans.

Aerobic respiration involves breakdown of glucose molecules to produce energy in the form of ATP molecule, in the presence of oxygen. During aerobic respiration, complete oxidation of one glucose molecule takes place to provide 36 ATP molecules.

Anaerobic respiration involves breakdown of glucose to provide energy, in the absence of oxygen. It shows partial or incomplete oxidation of glucose and one glucose molecule gives only 2 ATP molecules.

As 'aerobic respiration gives more ATP molecules that anaerobic respiration,' it is more beneficial than anaerobic respiration.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.
