When Amanda poured some of the liquid in a test tube, she noticed that the edges of the water curved upward, which is an example of adhesion.
When Pol filled another test tube to the top, the liquid formed a low dome, which is evidence of cohesion.
When Amanda added table salt to the first test tube and shook it, she noted that the liquid had dissolved the solute.
All of these observations indicated the presence of covalent bonds.
Pol determined that the pH of the sample is 7, which shows the sample is neutral.
Based on all of the evidence Amanda and Pol gathered, the unknown liquid is water.

A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.
Answer:
S.J. Singer and Garth L. Nicolson proposed the fluid mosaic model to describe the plasma membrane structure. They explained that the plasma membrane is a mosaic of carbohydrates, phospholipids, carbohydrates, and proteins.
This mosaic nature provides the fluid characteristic to the plasma membrane. This fluid behavior of the plasma membrane allows the movement of phospholipids and protein in the plasma membrane.
This movement of membrane components plays an important role in the transport of molecules across the cell.
