The characteristic of reactions that depends on valence electrons is the bond type.
In chemistry, a chemical bond could be;
The type of bond formed depends on the number of valence electrons present. When there are few valence electrons on an atom, it mostly forms ionic bonds.
When there are more electrons on an atoms, it mostly forms covalent bonds and the electrons between the atoms are shared.

Answer:
D. can control the transport of small molecules and ions.
Explanation:
Bilayers are critical components of cell membranes. The lipid bilayer acts as a barrier to the passage of molecules and ions into and out of the cell. However, an important function of the cell membrane is to allow selective passage of certain substances into and out of cells.
The lipid bilayers are highly permeable to non-polar (fat-soluble) molecules. The permeability of the bilayers to polar (water soluble) molecules is very low, and the permeability is particularly low to large polar molecules. The permeability to charged molecular species (ions) is very low.
Answer: Boiling and Evaporation: Evaporation is the change of a substance from a liquid to a gas. Boiling is the change of a liquid to a vapor, or gas, throughout the liquid.
