Physical
Building a tower of magnetic blocks is a physical change because the blocks are simply being rearranged without any chemical reactions taking place. The properties of the blocks themselves remain the same.
Physical change reason being it is
The universe building blocks are chemical elements. (I use Switched on Schoolhouse and this is the answer.) hope this helps :)
reaction time
Proteins are the macromolecules that provide building blocks for tissues and help regulate chemical reactions in the body. They are made up of amino acids that serve as the building blocks for building muscle, skin, and other tissues, and they also act as enzymes that catalyze chemical reactions in the body.
Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).
Chemical building blocks are the basic units or molecules that can be combined to form more complex chemical structures. These building blocks are used in various industries such as pharmaceuticals, materials science, and agriculture for creating new compounds through chemical synthesis. Examples include amino acids in proteins and nucleotides in DNA.
Atoms are the building blocks of molecules.
Amino acids, using the peptide bond.

the building blocks of substances are called what atoms or molecules?
