The diagram to the right shows a planet's orbit around the Sun. At which location is the planet's orbital velocity (speed) greatest?
A
Sun

According to the second Kepler's law:

A line joining a planet and the Sun sweeps out equal areas during equal intervals of time

The planet travels faster when closer to the Sun and slower when distant.

So the answer is point A

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.'
