The process illustrated here is somewhat different from those we have been studying, because the pressure change is due to changes in the amount of gas in the lung, not to temperature changes. (think of your own breathing. your lungs do not expand because they've gotten hot.) if the temperature of the air in the lung remains a reasonable 20 ∘c, what is the maximum number of moles in this person's lung during a breath?

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."
