1. a phospholipid has a made up of a glycerol molecule attached to a single phosphate group, which is attached to another small molecule. 2. phospholipids vary in the small molecules attached to the group. 3. because the group and its attachments are either charged or polar, the phospholipid head is hydrophilic, which means it has an affinity for water. 4. a phospholipid also has two "tails" made up of two which consist of a carboxyl group with a long hydrocarbon chain attached. 5. because the c-h bonds in the fatty acid tails are the phospholipid tails are hydrophobic, which means they are excluded from water.

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.
