Answer:

O floating around one another in a fluid structure

Explanation:

Cells are made up of varying types of molecules in order to achieve a fluid, stable plasma membrane. The membrane mainly consists of:

lipids
proteins
cholesterol

Lipid membranes help maintain selective membrane permeability. The lipids, formed from glycerol and saturated/unsaturated fatty acids, are made up of polar heads and non-polar tails; they typically only allow the movement of small non-polar molecules. Larger molecules are transported through integral proteins; other types, are peripheral, and may have specialized functions like cell signaling.

Cholesterol molecules keep the lipids in place, and ensure membrane fluidity. In extreme temperatures, they help the membrane to maintain its shape without becoming too rigid.

Andrew [12]

When a person is startled by a nearby car horn, the sympathetic nervous system will increase its activity. This part of the nervous system will activate the person's fight-or-flight response. It will help the person decide whether to fight aggressively or to flee quickly. In this case, it will tell the person to quickly move away from the car.
