Respuesta :
1. Answer;
-Head
A phospholipid has a "head" made up of glycerol molecule attached to a single phosphate, which is attached to another smaller molecule.
2. Answer;
-Phosphate group
Phospholipids vary in the small molecules attached to the phosphate group.
3. Answer;
Phosphate group
Because the phosphate group and its attachments are either charged or polar, the phospholipid head is hydrophilic, which means it has an affinity for water.
4. Answer;
Fatty acid molecules
A phospholipid also has two "tails" made up of two fatty acid molecules, which consist of a carboxyl group with a long hydrocarbon chain attached.
5. Answer;
-Non-polar
Because the C-H bonds in the fatty acid tails are relatively non polar , the phospholipid tails are hydrophobic, which means they are excluded from water.
