Question

in an oil spill, why does the oil not mix with the seawater?
lipids are hydrophobic.
lipids are hydrophilic.
lipids are saturated.
lipids are unsaturated.

Explanation:

Lipids are non - polar molecules. Water is a polar molecule. Hydrophobic substances (non - polar) do not mix with hydrophilic (polar) substances. Saturated and unsaturated refer to the structure of lipid hydrocarbon chains (presence of double bonds) and are not related to solubility in water.

Answer:

Lipids are hydrophobic.
