Amino acids are needed to build proteins just as nucleotides are needed to create DNA.
Explanation;
-Amino acids bond together to make long chains. Those long chains of amino acids are also called proteins. Protein plays a crucial role in almost all biological processes and amino acids are the building blocks of it. A large proportion of our cells, muscles and tissue is made up of amino acids, meaning they carry out many important bodily functions, such as giving cells their structure.
-Nucleotides are the building blocks of nucleic acids; they are composed of three subunit molecules: a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group.

Answer: When sea ice forms in ocean salinity of surrounding ocean water increases. The salt plays an very important role in the ocean circulation.When sea ice is formed in an ocean then this indicates the insertion of salt into the ocean .The salinity of surrounding water increases as salt water is heavier i.e its density is more as a result of high density the water sinks.There is an exchange of salt takes place between ocean and the sea ice.This influences the ocean circulation and this circulation lasts upto several hundreds of kilometers.
