Answer:
The density would stay the same.
Explanation:
The density would stay the same as density is an intensive property meaning it doesn't change based on the amount of matter that you have.
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: B) proteins in the membrane act like gates to control entrance and exit of molecules.
Explanation: Plasma membrane is composed of phospholipids bilayer in which the hydrophobic regions of the phospholipids face each other to form the core of the bilayer. Proteins are embedded in the bilayer through an interaction between the amino acid side chains and the nonpolar acyl chains of the phospholipids. The embedded membrane proteins form channels for passage of ions and other molecules. Each membrane protein is selected for one or more ions or molecules that passes through it. The membrane is said to be semipermeable because it allows the passage of some molecules and excludes the passage of others.
