The efficiency indicates the manner in which the inputs are used by the system. Being efficient means the system uses inputs in a `right' way. If the input-output ratio is adverse, we say that the system is inefficient though it produces the desired output.
The question is incomplete. However, if we consider this cell as human cell - the cell contain 23 pairs of chromosomes.
Answer:
Chromosomes consists of the constricted DNA associated with the proteins. Different species has different chromosome number. Two main types of chromosomes are heterochromatin and euchromatin.
The human cells contain the 23 pairs of chromosomes or 46 chromosome. If the cell divides by the process of mitosis than the chromosome number will be same in parent as well as the daughter cell. The daughter cell 23 pairs of chromosomes. If the cell divides by the process of mitosis the cell has 23 chromosome number as the meiosis reduces the chromosome number upto half.
