Question

which four elements are the primary components of important biological molecules, such as proteins, carbohydrates, and lipids? view available hint(s) nitrogen, carbon, hydrogen, and oxygen calcium, nitrogen, carbon, and oxygen oxygen, carbon, hydrogen, and water sodium, hydrogen, carbon, and oxygen

Explanation:

Biological molecules like proteins, carbohydrates, and lipids are mainly composed of nitrogen, carbon, hydrogen, and oxygen. Carbon forms the backbone, hydrogen and oxygen are common in functional groups, and nitrogen is present in proteins (in amino - acid units). Water is not an element. Calcium and sodium are important for other biological functions but not primary components of these molecules.

Answer:

A. nitrogen, carbon, hydrogen, and oxygen
