Astudent is studying mitosis, in which a cell divides to form two cells. which of these shows the correct mathematical model for the process if nold shows the number of chromosomes in the parent cell and nnew shows the number of chromosomes the individual daughter cells?

The correct answer for the question that is being presented above is this one: "A) Nnew = Nold." The CORRECT mathematical model for the process if Nold shows the number of chromosomes in the parent cell and Nnew shows the number of chromosomes the individual daughter cells is that A) Nnew = Nold 

Here are the following choices:
A) Nnew = Nold 

B) Nnew = Nold/2 

C) Nnew = 2 × Nold 

D) Nnew = 4 × Nold
