Question

if phospholipids are dropped in water, they can form a ball - shaped structure called a micelle. the model shows the cross section of a micelle formed by phospholipids. the micelle is surrounded by water.
image of a micelle with labels hydrophilic head and hydrophobic tail
explain why phospholipids dropped in water form a micelle. complete the paragraph.
the phospholipid ▼ face away from the water because they are ▼.
the phospholipid ▼ face toward the water because they are ▼.

Explanation:

Phospholipids have a unique structure with a hydrophilic (water - attracting) head and a hydrophobic (water - repelling) tail. In an aqueous (water - based) environment, the hydrophobic tails of the phospholipids avoid contact with water, so they cluster together in the interior of the micelle, facing away from the surrounding water. The hydrophilic heads, on the other hand, are attracted to water, so they are oriented towards the outside of the micelle, in contact with the water. This arrangement is a result of the chemical properties of the phospholipid components and the principle of minimizing the interaction between non - polar (hydrophobic) regions and the polar water molecules.

Answer:

The phospholipid tails face away from the water because they are hydrophobic (water - fearing).
The phospholipid heads face toward the water because they are hydrophilic (water - loving).
