The correct answer is option 
.
The is an ion made up of two atoms nitrogen and hydrogen.
The polyatomic ions are those ions, which are formed by the binding of the two or more elements, which has a charge and act as an ion. As all others are formed by a single atom, they are not polyatomic, only is formed by two atoms, hence, it is an polyatomic ion.
Answer:
Malnutrition prevents cellular respiration from occurring, therefore preventing cellular reproduction, therefore preventing the growth of the body aka stunting growth.
Explanation:
SCIENCE
The answer is the conversion of ADP to ATP using light energy. Photophosphorylation occurs in the light stage of photosynthesis. There are two types of photophosphorylation; cyclic and non-cyclic. In cyclic (which occurs only in bacteria), only photosystem I is utilized in the process while in non-cyclic, both photosystems I and II are used. In non-cyclic photophosphorylation, in addition to ATP, NADH is also synthesized.
