That would be phospholipids. They are a major component of the plasma membrane and contain hydrophilic, as well as, hydrophobic properties.
In the phospholipids.
The lipid head is hydrophilic
The lipid tail is hydrophobic

Many organic molecules have an end that will dissolve in fat (this would be the hydrophobic end) and an end that will dissolve in water (this will be the hydrophilic end). As the ends are joined together by the rest of the molecule, the molecule has both properties at once and such molecules are frequently used in the formation of organic membranes.
Yes, it is correct.
A polar molecule is hydrophilic, which means that it will easily dissolve in water. Examples of hydrophilic molecules are sugars and salts.
The most notable characteristic is amphipathicity, meaning it is hydrophilic on one end and hydrophobic on the other. This allows it to form a bilayer, of which cell membranes are made. If a molecule were to cross through the membrane, it would need to diffuse through a hydrophilic region, a hydrophobic region, and another hydrophilic region, which is difficult for most molecules. This is why the phospholipid bilayer is a good way to separate a cell from its environment.
Because the heads of the phospholipids are hydrophilic (water loving) and the tails of the phospholipids are hydrophobic (water hating). The tails are pointing towards each other and the heads are facing the membranes.

Dna has a hydrophilic and hydrophobic side, also you have to remember that DNA is a polar molecule
They have both hydrophilic and hydrophobic heads. In a lipid bilayer, the hydrophilic head of the phospholipid faces the outside of the membrane while the hydrophobic head faces the the hydrophobic head of another phospholipid.

Amphipathic(1) Pertains to a molecule containing both polar (water-soluble) and nonpolar (water-soluble) portions in its structure.(2) Of, or relating to, a molecule having hydrophobic and hydrophilic regions.www.biology-online.org
The tail of a phospholipid molecule is hydrophobic, while the head is hydrophilic.
The head is hydrophilic and the tail is hydrophobic.
Phospholipid
Amphipathic molecules are molecules that contain a hydrophilic region (water-loving region) and a hydrophobic region (water-hating region). Therefore, phospholipids, which are amphipathic molecules that make up our cell membranes, form into bilayer bio-membranes naturally due to the hydrophobic forces of attraction between each phospholipid molecule and the water-hating nature of it forces the molecules to orientate themselves with their hydrophobic sections facing inward and their hydrophilic sections outward. I hope this helps! :)
