3. which of the following statements describes the structure of the plasma membrane?
the plasma membrane is made mainly from carbohydrates that give the cell energy.
it is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.
protein molecules make up the membrane, which makes it a strong structure.
it is made primarily of cholesterol that allows the cells to communicate with others.

The stateent "It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward" describes correctly the structure of the cell membrane.

Explanation: The cell membrane is composed mainly of phospholipids, in the configuration of lipid bilayer. Phospholipids are molecules that have a polar head (where phosphorus is found) and a hydrophobic (lipid) tail. The polar heads are oriented towards the outside of the bilayer, and the non-polar tails, towards the inside of it.

Although there are extructural proteins that are part of the cell membrane, they are not the major component. Although class proteins fulfill infinite functions, such as transport, association with sugars, structure, etc., without the lipid bilayer there would be no place where these proteins would be housed. The same goes for carbohydrates, which form an important role in the formation of the extracellular matrix, but they are not the most important component of the cell membrane.

B, is the correct answer

It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.

Explanation:

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:
