Question

the different parts of a phospholipid molecule have different properties. the phosphate head, which contains phosphorus and nitrogen atoms, is polar and dissolves in water. substances that mix with water are called hydrophilic, or water - loving. the fatty acid tails are nonpolar. nonpolar molecules do not mix with water. so the nonpolar tails in a phospholipid are hydrophobic, or water - fearing. molecules that have both a hydrophilic and a hydrophobic region are called amphipathic. the model shows a simplified representation of a phospholipid and its chemical structure. (the simplified representation does not show glycerol.) complete the sentence. a phospholipid is amphipathic because its and its polar and hydrophilic, nonpolar and hydrophobic.

Explanation:

A phospholipid has a phosphate - containing head which is polar and hydrophilic, and fatty - acid tails which are nonpolar and hydrophobic. This dual nature makes it amphipathic.

Answer:

phosphate - containing head is; fatty - acid tails are
