I Just need to know if option D is the correct one The balanced equation for photosynthesis is shown below.

6 CO2 + 6 H2O → C6H12O6 + 6 O2

What best explains whether mass is conserved or not conserved during photosynthesis?

It is not conserved because the total numbers of H atoms and O atoms are not equal on both sides.
It is not conserved because the total numbers of O atoms and C atoms are not equal on both sides.
It is conserved because the total number of H atoms on each side is 1.
It is conserved because the total number of O atoms on each side is 18.

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.'
