A substance that cannot be broken down into other substances by ordinary chemical procedures is a(n) _____. - element Organisms are largely composed of __ elements. - 11 About 25 of the 92 natural elements are known to be essential to life. Which four of these 25 elements make up approximately 96% of living matter? - carbon, hydrogen, nitrogen, and oxygen What determines solubility? - "like dissolves like" Atom - Smallest unit of matter that retains all the properties of that eleme...

plasma membrane - The membrane at the boundary of every cell that acts as a selective barrier, thereby regulating the cell's chemical composition. Ribosomes - complexes that make proteins; free in cytosol or bound to rough ER or nuclear envelope Golgi apparatus - active in synthesis, modification, sorting, and secretion of cell products Lysosome - digestive organelle where macromolecules are hydrolyzed, and autophagy Mitachondrion - organelle where cellular respiration occurs and mo...
