Question

which facts describe the structure and function of the cell membrane in keeping cells healthy? (select the three correct answers.) (1 point)
☐ semipermeable membrane that controls material movement
☐ double lipid layer with water-loving heads
☐ made only of water molecules
☐ still structure with no protein parts
☐ solid barrier that blocks all molecules
☐ contains built-in proteins and channels

Explanation:

The cell membrane's structure and function are key to cell health. It is a semipermeable double lipid bilayer with hydrophilic heads, containing proteins/channels for material control. Incorrect options misstate composition (water-only, no proteins) or permeability (solid barrier).

Answer:

A. Semipermeable membrane that controls material movement, B. Double lipid layer with water-loving heads, F. Contains built-in proteins and channels
