Sodium vs Potassium. Sodium and Potassium are naturally occurring alkaline metals that show many similarities in their behaviors. Both sodium and potassium ions are essential for all life forms. Both ions are highly reactive and easily dissolve in water which is why both are found more in seawater than on land.

Gene-what is, definition and function. Gene is a segment of coding DNA (DNA that instructs the structure and function of cells throughout the body) composed of a specific sequence of nucleotides.The gene is the basic unit of inheritance that directs every facet of the bodyâs appearance and functions. Genes align along chromosomes in pairs.Each CHROMOSOME (AUTOSOME) contains thousands of genes, except the sex chromosomes which contain only a few hundred genes. Each gene has a specific location on the chromosome, called its locus, and encodes a specific function (either a protein or RNA transcription).enes align along chromosomes in pairs.
