Cell —Answer: The basic living units of all plants and animals differ in structure and function
but are still considered __________, as they have many characteristics in common.
Protiens —Answer: The building blocks of _____________ are amino acids, which when
combined form the structure of many body tissues as well as the enzymes that regulate the rate
of chemical reactions in the body.
Products —Answer: In a decomposition chemical reaction reactants are broken down into
smaller, less complex ______________.

________________.
Extracellular —Answer: The cell membrane surrounds and supports the contents of the cell,
selectively preventing the entry of ___________ substances, that is substances found outside the
cell.
