<span>The basic building blocks of a cell membrane are phospholipids. Phospholipids contain a hydrophobic (insoluble in water) end made up of two fatty acid chains of nonpolar molecules such as carbons and hydrogens. The other end is hydrophobic (soluble in water) and contains polar phosphate molecules. These phospholipids are arranged in a bilayer with their hydrophilic end group exposed to water on each side of the membrane and the hydrophobic nonpolar molecules protected inside the double layer. </span>

postnew [5]

Answer:

osmosis

Explanation:

The process that was going is <u>osmosis</u>.

<em>Osmosis is the movement of water molecules from regions of high water potential to regions of low water potentials through a selectively permeable membrane.</em>

In this case, the membrane is only permeable to water movement and not ions and water molecules move from the side with pure water (which happens to have higher water potential) to the side with 4% sodium chloride until equilibrium in water potential is established between the two sides.

How is the types of venation in a plant related to the types of root it has and the number of cotyledons in its seeds?​

BigorU [14]

Answer;

-Phospholipids and protein

Explanation;

-The plasma membrane is composed of a phospholipid bilayer arranged back-to-back. It is also covered in places with cholesterol molecules and proteins. The plasma membrane is selectively permeable and regulates which molecules are allowed to enter and exit the cell.

- The membrane is an extremely thin layer of lipids and protein that forms outer boundary of every cell, It controls movement of molecules between the cell and its environment, Participates in joining cells to form tissues and organs and also plays important role in the ability of a cell to respond to changes in the cell's environment.
