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 transfers of most cells require water and if the body dosent have enough it will shut down
Interaction between two species as both attempt to use the same environmental resources is
Species
The answer to that is James Watson and Francis Crick although if you search up on a search engine who found it Francis Crick will only show up.
