They can enter your blood stream (via breathing/ingesting) and once in your bloodstream they can enter cells and mutate your dna, which can cause cancer/birth defects/ reproductive harm
        
                    
             
        
        
        
Answer:
As somatic cells are diploid (2n) 2n=56
gametes receive only haploid set so, n=28
 
        
             
        
        
        
Physical chemists study matter and energy, and there is chemical reactions in your body, and all living things have elements, like carbon.
I would say D
