Final answer:
Fats and oils can dissolve in fats through a process called micelle formation. They arrange themselves into structures called micelles where the hydrophobic tails are on the inside and the hydrophilic heads are on the outside. This allows them to dissolve in fats and oils.
Step-by-step explanation:
Fats and oils are amphiphilic molecules. This means that they have both hydrophobic and hydrophilic parts. When in water, they arrange themselves into structures called micelles, where the hydrophilic heads are on the outer surface and the hydrophobic tails are on the inside. This allows the fats and oils to dissolve in fats and oils.
