Answer:
Answer is Option C.
The concentration of organic molecules by the process of dehydration synthesis can facilitate their assembly into macro molecules.
Explanation:
Macromolecules are large molecules formed by covalent bonds between monomers. They are a growing chain of monomers assemble through a process called dehydration synthesis in which one monomer forms a covalent bond with another monomer by releasing a water molecule. This is a process that requires energy. For example, two glucose molecules (monomers) combine to form a single maltose molecule. As a new covalent bond forms between the two glucose molecules, a water molecule is released.
Evaporation is a process in which water vapor is formed from water. The tendency of dissimilar particles to stick together is known as adhesion.
