The diagram reveals that lipids and proteins are both parts of cell membranes. They have different functions because lipids work to А remove nucleic acids from the cell membrane, and proteins work to hold the cell membrane together. B hold the cell membrane together, and proteins move chemicals across the cell membrane. С stiffen the cell membrane, and proteins create fibers that attach to the ends of the lipids. D move chemicals across the cell membrane, and proteins work to store water in the cell membrane.

There is no diagram in this question but the question can still be answered without it.

B. hold the cell membrane together, and proteins move chemicals across the cell membrane

Explanation:

The fluid mosaic model, which describes the structure of the cell membrane, reveals that it contains both lipids and protein constituents. These components, however, performs different functions in the cell membrane of organisms.

The lipid component of the cell membrane, which comprises of glycolipids and cholesterol, hold the cell membrane together while proteins called transport proteins help move chemicals across the cell membrane.

they deliver oxygen to the blood

it would be rhyolitic hope this
