Answer:
D
Explanation:
This is because one of its orbital shells is not filled – the one with 1 electron. This atom will, therefore, want to lose this electron – it takes less energy to do this than gain 7 electrons -- to achieve stable electron configuration. This makes this atom very reactive in a chemical reaction.  Usually orbital shells of atoms begin with an S orbital shell that is filled with 2 electrons then P (x,y,z) orbital shells filled with 6 electrons total. There are also higher energy f and d orbitals that each take a maximum 10 and 14 electrons respectively. An atom is stable if its orbitals are fully filled.

Answer:
Nucleic Acids are precursor for Proteins. 
Explanation:
Proteins are formed( protein units called amino acids) by the decoding of specific nucleic acids to give specific Proteins. 
No nucleic acids don't provide energy, these are building block of genetic material (DNA). While Proteins provide energy. 
No proteins don't carry genetic information. 
Yes structure of protein is determined by nucleic acids because each nucleic acids code fir specific unit of amino acid which join to form protein. 
No subunits of nucleic acids are nucleotides where as subunits of Proteins are called amino acids.

Variations in evolution usually refers to variation of genes at a particular loci. This differs from diversity which is the total of genetic differences within a population. Speciation is the reproductive isolation of a subset of a population.
