The answer is the last one: All of the above.

Explanation for each option:

  • Phospholipid bilayer: This is a fundamental component of the plasma membrane according to the Fluid Mosaic Model. It forms the basic structure, providing a semi-permeable barrier that separates the interior of the cell from the external environment.

  • Integral and peripheral proteins: These proteins are embedded within or attached to the phospholipid bilayer. Integral proteins span the membrane and are involved in various functions such as transport and signaling. Peripheral proteins are attached to the surface and play roles in signaling and maintaining the cell's shape.

  • Glycolipids: These are lipids with carbohydrate chains attached. They are found on the extracellular surface of the plasma membrane and are involved in cell recognition and communication.

  • Glycoproteins: These are proteins with carbohydrate chains attached. Like glycolipids, they are important for cell recognition and signaling.

Since all these components are part of the plasma membrane as described by the Fluid Mosaic Model, the correct answer is "All of the above."

An unsuspecting bird is coasting along in an easterly direction at 4.00 mph when a strong wind from the south imparts a constant acceleration of 0.500 m / s^2. If the wind's acceleration lasts for 2.10 s, find the magnitude r and direction θ (measured counterclockwise from the easterly direction) of the bird's displacement over this time interval. Assume that the bird is originally traveling in the +x direction and that there are 1609 m in 1 mi. r= m θ=
