Silver is rarely used for structural purposes due to its high cost compared to other materials, like steel or aluminum. It is also softer and more malleable than other metals, making it less suitable for applications requiring strength and durability. Additionally, silver's tendency to tarnish and react with other substances makes it less practical for long-term use in structural applications.
Cholesterol is a substance that is found in animal cells but not in plant cells. It plays a key role in maintaining the structural integrity of cell membranes in animals.
The cell's membrane allows only certain substances to diffuse in and out of the cell.
Carbohydrates are not considered pure substances; they are organic compounds made up of carbon, hydrogen, and oxygen atoms. They can exist in various forms, such as sugars, starches, and fibers, and can be composed of different structural units (monosaccharides, disaccharides, polysaccharides). As a result, the term "carbohydrates" encompasses a wide range of compounds with varying properties. Pure substances, on the other hand, consist of only one type of particle, such as elements or compounds in a uniform state.
The permeability of the cell membrane controls which substances may pass in or out of the cell.
There is no compositional difference between snow and ice; only structural. They are both composed of water, though snow needs to form around a nucleus which can be any number of substances.

Structural proteins are essentially the only proteins found in virion. Using this phrase can also refer to proteins in small amounts.

Sodium can be separated into simpler substances only by chemical means. Water, salt, and gold are pure substances that cannot be separated into simpler substances by chemical means.
