Answer:
Cell adhesion molecules would help white blood cells to stick to the wall of the blood vessel, so they can permeate across the wall and go into the underlying injured tissue.
Explanation:
The cell adhesion molecules, also called CAMs, are a type of cell adhesion proteins on the cell's surface, they take part in the binding of other types of cells and work together with the extracellular matrix in the process of cell adhesion.
Long story short, the protein helps cells stick together or to the surrounding tissues, thus helping on the maintenance of tissue structure and function. In fully grown mammals (including humans), CAMs play an important and key role in creating force and movement, thus assuring the organs are able to execute their function.
In their role as "molecular glue", CAMs are important participants in the cellular mechanisms of growth, contact inhibition, apoptosis and diapedesis, and when their behavior goes haywire, they are associated with afflictions going from frostbite to cancer.

Microscopes allowed scientists to observe Prokaryotic cells which make up Bacteria and Archaea. These cells are small and contain no membrane- bound organelles. It allowed them to observe Eukaryotic cells with a nucleus and membrane-bound organelles that perform different life functions.

Answer:
Oil
Explanation:
Since, unlike oil, source like wind, solar, water etc. come naturally we don't and can't replace them but when the viscosity in oil has been used up it must be change to allow the proper functioning of the machine.
