Sound waves travel better through solid than through a gas. Explain why this is true.

solids are more tightly packed together (the molecules) than liquid or gas so it allows it to travel through vetter/faster

Explanation: Solids are packed together tighter than liquids and gases, hence sound travels fastest in solids. The distances in liquids are shorter than in gases, but longer than in solids. Gases are the slowest because they are the least dense: the molecules in gases are very far apart, compared with solids and liquids

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
