The phospholipid molecules of most membranes have

1. hydrophobic head and a hydrophilic tail.
2.hydrophilic head and a hydrophobic tail.
3. hydrophobic head and two hydrophobic tails.
4. hydrophilic head and two hydrophobic tails.
5. none of these.

Hydrophobic tail and a hydophilic head. The phospholipid bilayer alligns so that the phospate heads face out because they like water and the tails face in because they do not like water (hydophobic - phobic means scared)

(4) is the correct answer

Hydrophyllic head and hydrophobic tail (2)

2.Hydrophilic Head and a Hydrophobic Tail

one hyrdo phobic and two hydrophilic, basic biochem
