Control of respiratory processes is similar to control of cardiovascular in that . . . a. norepinephrine on alpha receptors causes bronchoconstriction b. epinephrine on beta 2 receptors causes bronchodilation c. somatic motor neurons release acetylcholine onto nicotinic receptors at ganglionic synapse d. alveolar radius can be regulated similar to capillary radius

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.'
