Living things are made of types of molecules, known as macromolecules.
There are four major classes of biological macromolecules:
carbohydrates
lipids
proteins
nucleic acids
Each of these types of macromolecules performs a wide array of important functions within the cell; a cell cannot perform its role within the body without many different types of these crucial molecules. In combination, these biological macromolecules make up the majority of a cell’s dry mass. (Water molecules make up the majority of a cell’s total mass.) All the molecules both inside and outside of cells are situated in a water-based (i.e., aqueous) environment, and all the reactions of biological systems are occurring in that same environment.
Answer:
<em>Intervertebral Disc.</em> <em>The bodies of adjacent vertebrae are separated and united by an intervertebral disc, which provides padding and allows for movements between adjacent vertebrae.</em>

A chromosome is a packaged and organized structure containing most of the DNA of a living organism. Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression. Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.
They’ve helped end/calm down pandemics and epidemics and allowed us to go out and start living our life again.
You don’t have to use this word for word just an idea
