Aphysiological buffer is a system, namely the digestive system, that stabilizes ph by controlling the body's output of acids, bases, or co2.
a. true
b. false

The statement above is true. Digestive system can be considered as a physiological buffer because it involves a process of secreting digestive enzymes and substances such as proteins, phosphate, bicarbonate, and hemoglobin in breaking down of food chemically. During digestion, the digestive system helps adjust the pH level of acids, bases or co2.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'

it depends on how much it could carry.
