Answer : The correct option is, (D) There would be no difference in the average kinetic energies.
Explanation :
Average kinetic energy : According to the kinetic theory of gases, an average kinetic energy of gas molecule is directly proportional to the temperature of gas molecule.
Formula of average kinetic energy is,
where,
K.E = average kinetic energy of gas molecule
R = gas constant
= Avogadro's number
T = temperature of gas molecule
The average kinetic energy depend only on the temperature. If the temperature will be same then there would be no difference in the average kinetic energies.
Hence, the correct option is, (D) There would be no difference in the average kinetic energies.

Answer:
DNA molecules are composed of four nucleotides, and these nucleotides are linked together much like the words in a sentence. Together, all of the DNA "sentences" within a cell contain the instructions for building the proteins and other molecules that the cell needs to carry out its daily work.
Explanation:
A strand of DNA is much like an extremely long sentence that uses only four letters. DNA actually has two strands, much like a zipper and the nucleotides are like the teeth of that zipper. This two-strand system is the key to how DNA is able to make copies of itself.
