hydrophobic.
The term that describes substances with both water-loving (hydrophilic) and water-fearing (hydrophobic) properties is "amphipathic." Amphipathic molecules, such as phospholipids, have hydrophilic heads that interact with water and hydrophobic tails that repel water, allowing them to form structures like cell membranes. This dual nature is crucial for many biological processes, including membrane formation and protein interactions.
If the water is impure, you could remove the impurities. If the water is pure, it's impossible to decrease the number of molecules without changing the number of water molecules, which would be the only kind of molecules present in that case.
They avoid water. (The word "hydrophobic" literally means "water-fearing" :D )
Water
Hydrophobic
Water-fearing molecules are called hydrophobic molecules. These molecules do not interact or mix well with water due to their nonpolar nature.
Hydrophobic molecules are water-fearing and tend to avoid interactions with water or other polar molecules. These molecules typically have nonpolar regions that make them incompatible with the polar nature of water, causing them to aggregate or form separate phases in aqueous solutions.
Lipids, such as fats and oils, do not dissolve in water because they are hydrophobic (water-fearing) molecules. This is due to their nonpolar nature, which prevents them from forming hydrogen bonds with water molecules.
Oils are hydrophobic, or “water fearing.” Instead of being attracted to water molecules, oil molecules are repelled by them. As a result, when you add oil to a cup of water the two don't mix with each other.
No. Hydrophillic freely associates with water, readily entering into solution, and water loving. Fats, or lipids, are hydrophobic, which are incapable of freely associating water molecules, insoluble, and water-fearing.
Ammonia is a polar molecule that can form hydrogen bonds with water molecules, so it is considered hydrophilic (water-loving) rather than hydrophobic (water-fearing).
Amphipathic molecules have both hydrophilic (water-loving) and hydrophobic (water-fearing) parts in their structure, while amphiphilic molecules have both hydrophobic and hydrophilic parts that are separate. Both types of molecules interact with water, but amphipathic molecules tend to form structures like micelles or bilayers, while amphiphilic molecules may form emulsions or monolayers.
Hydrophobia.
they have the gift of not fearing heights...
The term that describes substances with both water-loving (hydrophilic) and water-fearing (hydrophobic) properties is "amphipathic."

This dual nature is crucial for many biological processes, including membrane formation and protein interactions.
The primary structure of a cell membrane is a double layer of phospholipid molecules which have heads that are hydrophilic (water-loving). These face outwards and tails are hydrophobic (water-fearing) and these face inwards.Because of this polarity the molecules arrange themselves in bilayers in water.
The term for fearing water is 'hydrophobia'.
