What scientific knowledge about macromolecules is a direct result of gerardus johnannes mulder’s 1838 discovery? a. all proteins contain carbon, hydrogen, oxygen, and nitrogen. b. all carbohydrates contain carbon, hydrogen, and oxygen. c. nucleic acids are polymers with nucleotide monomers. d. the helical structure of dna is essential for protein production.

Answer;

A. All proteins contain carbon, hydrogen, oxygen, and nitrogen.

Explanation;

Studies on proteins led Mulder to his protein theory (1838): he supposed that all albuminous substances consist of a radical compound (protein) of carbon, hydrogen, nitrogen, and oxygen, in combination with varying amounts of sulfur and phosphorus. The differences among proteins resulted from multiplication of the protein units in conjunction with the two other elements.

The answer is A -  All proteins contain carbon, hydrogen, oxygen, and nitrogen. I just did the review

-efficient data acquisition

-medical data processing

-data analysis for research

-voice recognition systems

it's anything that aren't producers and consumers.
