Answer:
The bonds that are formed between nitrogenous bases are Hydrogen Bond.
Explanation:
When a hydrogen atom  interract with an electronegative atom such oxygen,fluorine hydrogen bond forms,
               A single hydrogen bond is weak noncovalent bond but collectively  they exerts  very strong interraction.
             Hydrogen bonding occurs between complementary base pair .For exam An adenine base forms 2 hydrogen bonds with thymine base whereas guanine forms 3 hydrogen bonds with cytosine base.
              The hydrogen bonding between complementary is very much important to stabilize the structure of DNA .

The best answer is D. 
The mass number of an element is the sum of the number of protons and the number of neutrons. Protons and neutrons both weigh about one atomic mass unit or amu.
The nucleus of an atom is made up of protons and neutrons. Both these two types of particles are almost the same size.  Almost all the mass of an atom (99%) is in the nucleus. Atomic mass therefore is really a measure of the size of the nucleus.
 
        
                    
             
        
        
        
Because water is a polar molecule, it makes an excellent solvent for polar and ionic compounds found within cells and tissues.
