Question

The positioning of the phospholipids in the bilayer allows a cell to interact with its internal

and external environment.
Which of the orientations of the phospholipids above represents the phospholipid bilayer the
cell membrane must have in order to maintain homeostasis

Answer 1

The positioning of phospholipids in the cell membrane allows the cell to maintain homeostasis by regulating the movement of substances in and out of the cell.

Step-by-step explanation:

The positioning of the phospholipids in the cell membrane is crucial for maintaining homeostasis. The phospholipids form a bilayer with their hydrophobic tails facing each other and their hydrophilic heads facing towards the aqueous environments inside and outside the cell. This arrangement allows the cell membrane to regulate the movement of substances in and out of the cell, ensuring that the internal conditions remain stable.
