Verified answer

2 fatty acid chains

probably a....

water is polar, it obviously isnt hydrophobic and its not very large compared to other molecules

Plasma membrane is a bilayer phospholipid, the inside is hydrophobic, the outside (face extracellular fluid) are hydrophilic, polar head.

Phopholipid contains 1 glycerol, 2 fatty acids, 1 phosphate group

A. Water gets through because its a small molecule (since other answer are wrong, water is polar, small molecule, and hydrophilic)

Most phosphlipids are glycerol with one phosphate and two fatty acids liked (so the answer is 2)

water gets through b/c it's small

to one glycerol there is one phosphate group and 2 fatty acids attached

A

b- water is a classic example of a polar molecule

c- nahh its pretty small

d for doesnt make sense. hydrophobic literally means scared of water, so unless water is scared of itself........the answer is A
