Question

Select the statement that accurately summarizes cell membrane structure and

function.
The cell membrane consists of a phospholipid bilayer that consists of four layers
of molecules that function to prevent all particles from entering the cell.
The cell membrane consists of a phospholipid bilayer that contains water loving
molecules within the middle section that appear tail-like in structure.
The cell membrane consists of a phospholipid bilayer that consists of a top layer
that likes water and a bottom layer that does not like water.
The cell membrane consists of a phospholipid bilayer that contains water-loving
molecules facing the interior and exterior of the cell.

Answer 1

The cell membrane consists of a phospholipid bilayer with water-loving molecules facing the interior and exterior of the cell, allowing it to regulate substance movement and maintain homeostasis.

Step-by-step explanation:

The cell membrane consists of a phospholipid bilayer that contains water-loving molecules facing the interior and exterior of the cell. The phospholipid bilayer is made up of two layers, with the hydrophilic heads facing the water on both sides and the hydrophobic tails facing inward, away from the water. This structure allows the cell membrane to regulate the movement of substances in and out of the cell, maintaining homeostasis.
