The tail portion of an individual phospholipid molecule: Please choose the correct answer from the following choices, and then select the submit answer button. is hydrophobic and nonpolar. is hydrophilic and nonpolar. is hydrophobic and polar. is hydrophilic and polar. contains bonds with unequal sharing of electrons.

The correct answer is - hydrophobic and nonpolar.

Explanation:

Phospholipids are amphipathic molecules which means they show the both hydrophobic and hydrophilic properties. This property is due to the fact that they have a phosphate head that is hydrophilic, and polar while there are also two hydrophobic nonpolar fatty acid tails.

The fatty acid chains have a cis double bond and are the uncharged, nonpolar tails, which are hydrophobic.

Thus, the correct answer is - hydrophobic and nonpolar.
