Answer 2

Answer: The fill in the blank can be filled by Oxygen (65%), Carbon (18%), Hydrogen (10%), and Nitrogen (3%)

Oxygen and hydrogen are predominantly present in water ($H_{2}O$). Water comprises of 60% of the total body weight.

Nitrogen is present in several organic molecules. For example- It is present in the amino acids which make up proteins, and the nucleic acids which make up DNA.

Carbon is the basis of all organic compounds which are essential to life.Due to the presence of four bonding sites, it allows the formation of complex chains of molecules.
