Answer:
2n=46(duplicated)
Explanation:
Prior to cell division, which can either be meiotic or mitotic, the DNA content of the cell gets doubled in the Synthesis phase of the Interphase stage. In humans like myself, our cells consist of 23 pairs of chromosomes or 46 chromosomes. The DNA doubles in order for each daughter cell to get the correct number of genetic material.
After the S-phase, the chromosome number in the human cell does not change, just that each individual chromosome gets replicated or duplicated to form sister chromatids. Therefore, the human cell will contain 46 duplicated chromosomes or 92 sister chromatids after Synthesis phase and before the meiotic division.
Note that, humans are diploid organisms (2n) i.e. two set of chromosomes. Hence, they undergo meiosis to reduce their ploidy level from diploid (2n=46) to haploid (n=23).
The answer is B) ATP + oxygen --> ADP + P
Adenosine triphosphate (ATP) is the energy currency stored in every living cell. ATP is a complex molecule which composed of the nucleoside adenosine and a tail of three phosphates. Normally energy is released from the ATP molecule by a reaction that removes one of the phosphate-oxygen groups and becomes adenosine diphosphate (ADP). Thus, ATP converts to ADP to liberate energy. ADP soon after release, it is recharged in the mitochondria and comes out again as ATP.
