They are nonmetals.
All proteins contain carbon, hydrogen, oxygen and nitrogen. Most of them also contain sulfur, which is found in the standard amino acid residues cysteine and methionine (any given protein might not contain either of these, though it would be unusual).
The most abundant elements in the universe, in order from most to least abundant, are Hydrogen, Helium, Oxygen, Carbon, and Nitrogen. Therefore, the correct list would start with Hydrogen, followed by Helium (not listed), then Oxygen, Carbon, and finally Nitrogen. The first option you provided, "Hydrogen Oxygen Nitrogen Carbon," is almost correct but is missing Helium and has an incorrect order for Nitrogen and Carbon.
That answer would be carbon Sources: Biology teacher.
Hydrogen, Carbon, Oxygen, and Silica are the most common elements found in the Earth.
Carbon dioxide form a milky suspension of calcium carbonate in calcium hydroxide; hydrogen doesn't react. But hydrogen react with oxygen when a flame exist.
Hydrogen, Carbon and Oxygen.It is easy to remember by breaking down the word. Carbois for Carbon. Hyd is for Hydrogen and ate means Oxygen is present.
The human body is made up of only mostly carbon, oxygen, hydrogen, nitrogen, calcium, and phosphorus. The top four elements are oxygen, carbon, hydrogen and nitrogen, so that would be a. on your list.

This would be a gas mixture containing carbon dioxide, oxygen, and hydrogen. It is important to note that this particular combination is not commonly found in nature and would likely require intentional mixing of gases by humans.
The three most common elements found in living things and important to the human body are carbon, hydrogen, and oxygen. These elements play a crucial role in forming organic molecules such as carbohydrates, lipids, proteins, and nucleic acids essential for life processes.
The chemical name for Carbon 12 Hydrogen 22 and Oxygen 11 would be C12H22O11, which is commonly known as sucrose or table sugar.
Each molecule of pyruvic acid has 3 carbon atoms, 4 hydrogen atoms, and 3 oxygen atoms. Therefore, two molecules of pyruvic acid would have a total of 6 carbon atoms, 8 hydrogen atoms, and 6 oxygen atoms.
Hydrogen, Carbon, Oxygen, and Silica are the most common elements found in the Earth.
Any alcohol would contain these 3 elements.
