1. Hydrophilic 2. Hydrophobic
Explicação
## Step 1Phospholipids are a crucial component of all cell membranes. They are composed of a hydrophilic (water-loving) head and two hydrophobic (water-avoiding) tails. ## Step 2The hydrophilic head of a phospholipid is attracted to water. This is due to the fact that the head is composed of a phosphate group, which is polar and thus, can form hydrogen bonds with water molecules.## Step 3On the other hand, the hydrophobic tails of a phospholipid repel water. This is because the tails are composed of fatty acid chains, which are nonpolar and thus, cannot form hydrogen bonds with water molecules.## Step 4When phospholipids come together to form a bilayer, the hydrophilic heads face outwards, towards the water, while the hydrophobic tails face inwards, away from the water. This arrangement allows the phospholipids to maintain a stable structure in an aqueous environment.
