Answer:
Because liquids and solids are denser than gasses.
Explanation:
Solids and liquids are denser than gasses making it easier for things like sound to conduct through them. Being dense contributes to a better conduction because the particles and such within the solid or liquid are closer together which allows for things like sound to travel at a much faster rate because they're so much easier to vibrate.
The correct answer is protein.
Proteins are macromolecules composed of amino acids with the wide range of structures. Protein functions are diverse:
• structural proteins-maintaining the cell shape, (for example, proteins are structural elements in connective tissues like cartilage and bone in vertebrates),
• Enzymes - catalyze the biochemical reactions in cells-.
• Monitors- changing their activity in response to metabolic signals
• Part of the extracellular matrix or involved in intercellular communication…
