Answer:
Option (D)
Explanation:
The entropy is usually defined as the measure of the total thermal energy of a system per unit temperature. This amount of energy is used in performing valuable work. In simple words, it can be said that entropy is related to the disorder or degree of randomness of a particular system. This entropy concept gives proper information regarding the direction along which natural change occurs and is frequently observed in many present-day events.
Thus, the correct answer is option (D).

Answer:
The correct answer is both.
Explanation:
- Each chromosome is made up of a pair of sister chromatids which remain attached to each other at the centromere.
- During DNA replication the DNA duplicates, which means that if initially in the parent cell 'n' chromosomes were present then, after duplication, the number of chromosomes in the cell will be '2n'.
- As mentioned above, each chromosome has a pair of sister chromatids, that is, two chromatids per chromosome. So, 'n' chromosomes will have '2n' chromatids. Hence, '2n' chromosomes will have '4n' chromatids.
- In a parent cell,
- Before duplication, number of chromosome = n, number of chromatid = 2n.
- After duplication, number of chromosome = 2n, number of chromatid = 4n.
- The cell cycle proceeds as, G0, G1, S, G2, M.
- G0 represents the interphase. It occurs before replication or duplication of the chromosomes, which occurs in the S phase.
- So, in G0 phase, the chromosome number is 'n' and chromatid number is '2n'.
