Question

why do phospholipids form bilayers in water? choose one: the hydrophobic tail is attracted to water, while the hydrophilic head shuns water. the hydrophilic head is insoluble in water. the hydrophobic head shuns water, while the hydrophilic tail is attracted to water. the hydrophilic head is attracted to water, while the hydrophobic tail shuns water. the hydrophobic head is attracted to water, while the hydrophilic tail shuns water.

Explanation:

Phospholipids have a hydrophilic (water - loving) head and a hydrophobic (water - fearing) tail. In water, the hydrophilic heads are attracted to the water molecules, while the hydrophobic tails try to avoid water. To minimize contact with water, the phospholipids arrange themselves in a bilayer with the hydrophilic heads facing the water and the hydrophobic tails facing each other in the interior.

Answer:

The hydrophilic head is attracted to water, while the hydrophobic tail shuns water.
