Biology

The correct answer is G.

 

Explanation:

The lipid heads in the cell membrane are hydrophilic (water-loving), and they face outward, towards the aqueous environment, because they are attracted to water. The tails, on the other hand, are hydrophobic (water-fearing) and point inward, away from the water. This arrangement forms a phospholipid bilayer, where the hydrophilic heads are on the outside and the hydrophobic tails are on the inside.

 

Here is a breakdown of the options:

A: Describes the overall arrangement of the lipid bilayer, where the heads are outward and the tails inward, but this is not a direct answer to the question.

B: Refers to proteins that span the ...
