Which situation probably involves autoantibodies?

Biological markers

Homeostasis

House keeping

Explanation:

Autoantibodies are also reffered to as natural antibodies. This antibody react with self molecules in the body system to fight against infection.

This antibodies are produced by genes that are not mutated.

They provide the immediate defence against disease or infection and help in keeping the body fit.

They are useful in the regulation of body function or activities i.e homeostasis

Autoantibodies are useful as biological marker in targeting some disease that are present in the body as they could be specific to certain organs in the body.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
