The efficiency of work is a dimensionless value, and is equivalent to the ratio of the actual work output to the theoretical work requirement. This can be calculated using the equation:
Efficiency = (actual work) / (work requirement) = 123/150 = 0.82
The higher the efficiency, the better performance is given by the system. In reality, efficiency is always lower than 1 which is the ideal value.
IN between the G1 and the G2 phase of the cell cycle the cell's DNA replicates its DNA. The number of chromosomes stays the same, but the amount of DNA molecules duplicates.
Therefore, our cell with 6 chromosomes in the G2 phase has 6 chromosomes and 12 DNA molecules.
