Question

cell membrane exit ticket phospholipids have two parts, a ____ head and a ____ tail, that helps allow membranes to be selectively permeable. hydrophobic, hydrophilic hydrophilic, hydrophobic non - polar, polar hydrocarbon, phosphate

Explanation:

Phospholipids have a hydrophilic (water - loving) head due to the phosphate group which can interact with water, and a hydrophobic (water - fearing) tail made of fatty acid chains that avoid water. This structure is crucial for the selective permeability of cell membranes.

Answer:

B. Hydrophilic, Hydrophobic
