Antigens- Each human being has his or her own unique cell surface antigens, as do to all other living things, including bacteria, virus, animals, and plants.

Molecules on the outer surface of a cell that identify it as "self" or "foreign" are called antigens. These antigens play a crucial role in the cell's ability to distinguish between its own cells and potentially harmful foreign cells. The recognition of self-antigens helps the immune system to tolerate the body's own cells while identifying and attacking foreign invaders.

What molecules are on the outer surface of the plasma membrane?
Lipids such as phospholipids, cholesterol, and glycolipids, as well as proteins like glycoproteins and receptor proteins are found on the outer surface of the plasma membrane. These molecules help provide structure, facilitate cell-cell recognition, and play roles in cell signaling and communication.
Peripheral protein on the outer surface?
Peripheral proteins are proteins found on the outer surface of the cell membrane. They are not embedded within the lipid bilayer, unlike integral proteins. These proteins often serve as receptors for signaling molecules or help with cell adhesion.
Structure and properties of inner and outer surface of centrifugal casting?
In centrifugal casting, the outer surface is typically smoother than the inner surface due to the centrifugal force exerted during the process, which pushes impurities towards the inner surface. The outer surface also tends to have a finer grain structure compared to the inner surface. The inner surface may exhibit greater porosity and can be more susceptible to defects due to the cooling process occurring more rapidly on this surface.
What is the area to cell's outer surface in relationship to it's volume?
The surface-area-to-volume-ratio
What is the scientific name for earth's outer layer of surface soil or crust?
The scientific term for Earth's outer layer of surface soil or crust is the lithosphere. This includes the crust and uppermost part of the mantle, forming the rigid outer shell of the Earth.
On the outer surface of the plasma membrane there are marker molecules that identify the cell-type Often these molecules are?
proteins or lipids, known as glycoproteins or glycolipids, that serve as markers to identify the cell type. These markers play a critical role in immune responses, cell communication, and recognition by other cells.
Atmospheric molecules do not fly off into outer space because of?
the gravitational pull of Earth. This force keeps the atmospheric molecules bound to the planet's surface, preventing them from escaping into outer space.

When water is deeper does it have a thicker water surface tension?
No, surface tension is a phenomenon of a single outer layer of molecules, so it is not affected by the depth of the water underneath it.
If water spreads out on a glass plate is this an example or cohesive or adhesive force?
Both, the water molecules are cohesive to each other, and the outer water molecules are adhesive to the table surface.
Peripheral protein on the outer surface?
Peripheral proteins are proteins found on the outer surface of the cell membrane. They are not embedded within the lipid bilayer, unlike integral proteins. These proteins often serve as receptors for signaling molecules or help with cell adhesion.
What is a curved outer surface of a circle?
The curved outer surface of a circle is the perimeter.
What is the covering of the outer surface of bone?
The outer surface of the bone is called the periosteum.
How do you identify hoofed animals?
we identify them by their outer covering, behaviour and their stances
What is the definition of cell surface area?
The surface area of a cell is defined as the total area encompassing the perimeter of the outer cell layer. The surface area of a cell is an important part of the Surface Area to Volume Ratio in terms of the effect it has on molecules that are entering or exit the cell.
What is another word for earths outer surface?
Another word for Earth's outer surface is "crust."
Surface of an insects?
they have coating of wax on the outer surface of their body
