The fundamental component for all of these macromolecules is carbon. The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.

Roles of DNA and RNA in cells Nucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

“Nucleic acid” is the term we use to describe specific large molecules in the cell. So they’re actually made of polymers of strings of repeating units, and the two most famous of the nucleic acids, that you’ve heard about, are DNA and RNA. And nucleic acids in the cell act to actually store information.

DNA

Nucleic acids are the macromolecules made out of units called nucleotides. Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are two naturally occurring varieties. HOPE IT HELPS U DEAR.

Nucleic acids include RNA (ribonucleic acid) as well as DNA (deoxyribonucleic acid). A: All biochemical compounds contain carbon, hydrogen, and oxygen; and proteins as well as nucleic acids contain nitrogen.

The four main classes of organic compounds (carbohydrates, lipids, proteins, and nucleic acids) that are essential to the proper functioning of all living things are known as polymers or macromolecules. All of these compounds are built primarily of carbon, hydrogen, and oxygen but in different ratios.

11.1 Introduction: The Four Major Macromolecules These are the carbohydrates, lipids (or fats), proteins, and nucleic acids.

As we’ve learned, there are four major classes of biological macromolecules:

• Proteins (polymers of amino acids)
• Carbohydrates (polymers of sugars)
• Lipids (polymers of lipid monomers)
• Nucleic acids (DNA and RNA; polymers of nucleotides)

For example, macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions. Four major types of macromolecules—proteins, carbohydrates, nucleic acids, and lipids—play these important roles in the life of a cell.

Many elements make up the human body, but only three occur in abundance. These elements, oxygen, carbon, and hydrogen, combine to form the constituents of some of the most essential processes in the human body, such as cellular respiration.

Three Elements

• We all know oxygen, silicon, and aluminum are common elements in the Earth’s crust.
• The combined occurrences for these three elements are very well known.
• For all three together, we find the mineral kyanite.

The four elements common to all living organisms are oxygen (O), carbon (C), hydrogen (H), and nitrogen (N).

The four most important elements in cells are carbon, hydrogen, oxygen and nitrogen. However, other elements — like sodium, potassium, calcium and phosphorus — are also important.

Oxygen

The function of chemical elements in the body

• Oxygen. Oxygen is the most common element in the human body, comprising approximately 65.0% of body mass.
• Carbon. Carbon is the next most common element in the human body, making up 18% of the body by mass.
• Hydrogen.
• Nitrogen.
• Calcium.
• Phosphorus.
• Potassium.
• Sulfur.

magnesium

Astatine is the rarest naturally occurring element.

The hardest pure element is carbon in the form of a diamond. Diamond is not the hardest substance known to man. Some ceramics are harder, but they consist of multiple elements. Not all forms of carbon are hard.

As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume.

The answer is: wheat. Actually, the entire agriculture complex, including corn, beef, pork and beans could fit this description.
