The correct answer would be D, because the ending result for mitosis is 2 diploid cells, meaning the number chromosomes are the same. While in meiosis, the ending result is 4 haploid cells. Because the cell was divided twice, this means that each daughter cell has half of the number of chromosomes.
        
             
        
        
        
It would be 10
Atomic number = Number of protons
so, 10 = 10
Option D is your answer.
Hope this helps!
        
             
        
        
        
The statement about boiling points that is true is the boiling point of a substance is higher than its freezing point.
If something boils, it means it is really hot in there, and if it freezes, it is very cold.
