Answer:
The phospholipid will form a sphere with the heads inside
Explanation:
Phospholipids are glycerol molecules containing two Fatty acids that is hydrophobia and a hydrophillic negatively charged phosphate.
The phosphate forms the head and the two fatty acids will form the tail
When phospholipid is dropped into a cup of vegetable oil (a lipid). The phospholipid will form a sphere with the heads inside. This is because the heads are hydrophillic and cannot dissolve in the fat hence they will cluster together.
