A swimmer jumps into a pool and does a cannonball, creating a big splash. Which statement explains the energy exchange as the swimmer hits the pool water?
A. Kinetic energy of the swimmer is transformed into potential energy of the pool water.
B. Kinetic energy of the swimmer is transferred to the pool water.
C. Potential energy of the swimmer is transferred to the pool water.
D. Potential energy of the swimmer is transformed into kinetic energy of the pool water.

answer; both surfaces of the membrane are nonpermeable

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.'
