-They are polar
Explanation;
-A phospholipid is a lipid that contains a phosphate group and is a major component of cell membranes. A phospholipid consists of a hydrophilic (water-loving) head and hydrophobic (water-fearing) tail. Hydrophilic / hydrophobic layers restrict the passage of many substances.
-When phospholipids are mixed with water, they spontaneously rearrange themselves to form the lowest free-energy configuration. This means that the hydrophobic regions find ways to remove themselves from water, while the hydrophilic regions interact with water.

Relative dating can only tell you which strata are older or younger than others. The dates are floating, and are in need of anchoring. That is where absolute dating, using radiometric dating techniques for example, come into play. They can fix certain of the strata at particular age, anchoring them solidly and leaving far less leeway for those strata above and below them, and especially for strata sandwiched between two absolutely-dated strata.
