Question

multiple choice question within the structure of a cell membrane, the phospholipid heads face __, while the tails face __. o the cytosol and extracellular fluid; each other o the extracellular fluid; the cytosol o each other; the cytosol and extracellular fluid o the interior of the membrane; the cytoplasm

Explanation:

Phospholipids in cell membranes have hydrophilic heads and hydrophobic tails. The hydrophilic heads face the aqueous environments, which are the cytosol (intracellular fluid) and the extracellular fluid. The hydrophobic tails face each other in the interior of the membrane to avoid water - based environments.

Answer:
