Aship is able to float on water because it has a higher density than the water.

False.

Explanation:

The ship is capable of floating because its average density (considering the steel part and the air filled part) is less than the water density. Moreover, it is in equilibrium, partially immersed and subject to the action of two forces of the same and opposite modulus, the weight P and the thrust E, exerted by water.

But the stability of the ship does not depend on it alone. It also depends on the point of application of these forces. The weight force is applied to the center of gravity (CG), which is fixed, and the thrust is applied to the center of thrust (EC), which is variable.

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.'
