Answer:
substances can move from areas of low concentration to areas of high concentration
Explanation:
usually substances move across their concentration gradient which is from high concentration to low concentration. Active transport can allow substances to move against their concentration gradient.
 
        
             
        
        
        
Polymers are made of individual subunit called monomer.
<u>Explanation:</u>
Polymers are lengthy chains built up of replicating molecular subunits, named monomers. The term polymer becomes from poly- (many) and -mer (part). A polymer may be a real or manufactured macromolecule composed of recurring units of a smaller molecule (monomers). The term monomer comes from mono- (one) and -mer (part). 
 Monomers make polymers by creating chemical bonds or confining supramolecular by a method called polymerization. Examples of polymers comprise plastics like polyethylene, silicones. Polymerization is the method of covalently bonding the smaller monomers into the polymer. While polymerization, chemical groups are failed from the monomers so that they may join together.

Answer:
The statement “force equals mass times acceleration” is Newton's second law of motion. It is a law rather than a theory because it states, rather than explains, the relationship between the variables.
