What property makes phospholipids ideal building blocks for cell membranes? They have hydrophilic heads and tails.

They have hydrophilic heads and hydrophobic tails.

They have hydrophobic heads and hydrophilic tails.

They have hydrophobic heads and tails.

They have hydrophilic heads and hydrophobic tails.

Explanation:

Phospholipid membranes are comprised of a chain of lipids. These typically are arranged in a bilayer; the hydrophilic lipid heads are polar, and face outwards, while the hydrophobic tails are polar facing inwards.

The membranes are selectively permeable, and only allow the movement of small, non-polar molecules through the bilayer.

the genotypes would be 50% bb and 50% bb

the phenotypes would be 50% brown and 50% white. hope this : )
