When sound waves interfere to create standing waves, the points on the
medium that move up and down with the largest amplitudes are called nodes. true or false

Explanation:

The correct answer should be antinodes not nodes.

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.'

im not intirely sure but i think the anwser is d relative humidity
