First, we can eliminate 2 options. The simple unit of protein is amino acid, instead, the simple unit of fat and lipids are fatty acids and glycerol, therfore we can eliminate option A and D because fatty acids does not exist in protein.
Now we are left with B and C. To solve that, we need to understand that protein is made of a chain of amino acids, a lot of amino acids are chemically combined and cannot be broken down unless the use of enzymes. Amino acid are actually the monomers that forms protein.
Therefore, the answer is C. amino acid combine to form a protein chain.
The difference between an amniotic egg and eggs laid by other animals is : Absence of Membrane ( amnion ) and absence of larval stage
<h3>Characteristics of an amniotic egg</h3>
Eggs laid by amniotes are different from other eggs laid by fishes, amphibians and invertebrates in that they lack a membrane and a larval stage. the shell of the amniotic egg protects the embryo in the absence of a membrane. The shell also allows for the exchange of oxygen and carbon dioxide between the the embryo and the environment.
Hence we can conclude that The difference between an amniotic egg and eggs laid by other animals is : Absence of Membrane ( amnion ) and absence of larval stage

Answer:
Cell wall. The plant cell wall accounts for the turgidity and the rigidity in plants. The cell wall protects the plant cell from bursting due to the influx of water. Rather than bursting, the cell is able to withstand the osmotic pressure exerted by the water molecules.
