Use a hot-air balloon moving across the sky as an example to explain how speed, velocity, and acceleration are different.

Speed is how fast its going in the air

Velocity is how high up the balloon is

Acceleration is how much faster you are starting to go

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.'

i wish i could with all of them i can barley see the first one so here's the answer to the first one b
