The picture shows water being dropped on a penny. How do the properties of water contribute to the water holding together on the
penny?
Cohesion allows droplets to form, and capillary action keeps them on the penny.
Adhesion allows droplets to form, and capillary action keeps them on the penny.
Cohesion allows droplets to form, and adhesion keeps the drops on the penny.
Adhesion allows droplets to form, and cohesion keeps the drops on the penny.

Explanation:
The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.
Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.
So, salt, water, and fats do not contribute to the movement of larger molecules, but <u>channel or transport proteins do and choice A is correct. </u>
