Answer: A. Cell membrane

Explanation: Cell membrane is a biological lipid bilayer that separates the interior part of every cell from its exterior. The main components of cell membrane include lipids, proteins and carbohydrate moieties that are attached to either lipids or proteins.

Cytoskeleton contains series of intercellular proteins that gives shape and provides support to a cell. Enzymes are proteins that catalyze biological reactions. Receptors are proteins found mostly on the surface of a cell.

A. Cytoskeleton
Because Enzymes and Receptors are proteins and a cell membrane is a barrier so it can’t really contain anything

Which membranes line the passageways that open to the exterior of the body, including those of the respiratory, digestive, repro
jenyasd209 [6]

Mucous membranes line the passageways that open to the exterior of the body, including those of the respiratory, digestive, reproductive, and urinary systems in the body.

A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue.

It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, lips, the genital areas, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated.

One of its functions is to keep the tissue moist (for example in the respiratory tract, including the mouth and nose).  It also plays a role in absorbing and transforming nutrients.  

Mucous membranes also protect the body from itself. For instance, mucosa in the stomach protects it from stomach acid and mucosa lining the bladder protects the underlying tissue from urine. In the uterus, the mucous membrane is called the endometrium, and it swells each month and is then eliminated during menstruation.
