What was the smallest voltage required to produce a contraction (the threshold voltage)? what proportion of the fibers in the muscle do you think were contracting to produce this small response?.

the glands which are associated with each description is given below:

a symbiotic relationship with the mitochondria

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.'
