You eat a french fry. As you chew and swallow, some of the particles go down the ‘wrong tube' (the trachea), and this causes you to cough. The specialized hair-like cell structures that detected this particle in your trachea and triggered the coughing response are called , and are an example of cell specialization, and how structure depends on function.

Your answer is "Cilia".

i would say it is

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.'
