expeople1 [14]

Answer:

The correct answer is C) arachnoid mater.

Explanation:

Arachnoid mater, along with pia mater and dura mater, form the <u>meninges</u>, a very thick membrane that protects the brain and the spinal cord. The arachnoid mater is in the middle of the other two layers and it is very important since it holds the <u>cerebrospinal fluid (CSF)</u> in its interior. Arachnoid mater has finger-like projections that enter the dural venous sinuses and are called <u>arachnoid villi</u>. These villi are responsible for the diffusion of CSF into the blood.

valina [46]

The structure of the plasma membrane makes this type of transport necessary for fluids is discussed below:

<h3>What do you mean by phospholipid membrane?</h3>

The membrane that divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and is present in all cells. A cell wall is affixed to the plasma membrane on the exterior of bacterial and plant cells.

Because water and other polar or charged substances cannot easily traverse the hydrophobic core of the membrane, the phospholipid bilayer created by these interactions serves as an effective barrier between the interior and exterior of the cell.

The composition of a cell differs from that of the cell membrane in that the cell membrane is?
blsea [12.9K]

Answer: The cell membrane is a bilayer of lipids composed mainly of lipids and proteins.

Explanation: A cell is the functional unit of life. A cell is usually surrounded by the cell membrane. A cell is composed of different organelles such as the nucleus, mitochondria, ribosome, each also surrounded by a membrane and these organelles are suspended in the fluidy part of the cell know as the cytoplasm.

A cell membrane is a thin lining that surrounds the cell and encloses the cytoplasm. It is made up of two layers of lipids in which proteins are embedded. Cell membranes allow the selective passage of materials into and out of the cell.
