Explanation:
In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.
Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.
Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.
Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.
Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.
- Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
- This leaves a partial negative charge on it.
- The other electron then becomes partially positively charged.
- We can then say, the more electronegative specie undergoes reduction.
- The less electronegative one undergoes oxidation.

It would decrease as their prime food source would be taken away. This would result in a decline in population as the birds wouldn’t have sufficient food.
Hope that helps. :)
Answer – D. RNA
Like proteins, Ribonucleic acid is another kind of organic molecule that also acts as a catalyst for chemical reactions. Asides acting a catalyst for chemical reactions, proteins have a wide variety of functions that they perform in in living cells.
