Question

What can you conclude about the advantage of the double-layer arrangement of a cell membrane?

Controlling what enters the cell must be important to its health.

Hydrophilic ends must react easily with non-polar molecules.

The cell must need to repel liquids within the phospholipids bilayer.

Hydrophobic ends must be required for cellular reproduction.

Answer 1

The cell must need to repel liquids within the phospholipids bilayer. im pretty sure

Answer 2

@beccaboo333 can you explain why?

Answer 3

yes give me a moment to explain

Answer 4

The phospholipid bilayer is the two-layer membrane that surrounds many types of plant and animal cells. It's made up of molecules called phospholipids, which arrange themselves in two parallel layers, forming a membrane that can only be penetrated by certain types of substances. This gives the cell a clear boundary, and keeps unwanted substances out. Though the phospholipid bilayer works well most of the time, it can be damaged, and some types of unwanted substances can bypass it.
wasnt sure how to exactly explain it. here's the link. what i typed was from the link
