A simple schematic of a dammed river is shown above. In which area of the diagram would there be an increase in silt deposition compared to a decrease in fertile soil?

Increased silt deposition would occur at A while decreased fertile soil would occur at B. Flooded areas before a dam would have higher silt deposition, which would prevent the natural flow of water and silt deposition downstream.

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.'
