The subduction zone is the area where a less dense plate collides with a denser plate, causing the subduction of this last one. The correct option is D. a subduction zone
<h3>
What is a subduction zone?</h3>
The term subduction refers to the sinking process of one plate under another plate after a collision event.
Subduction zones are the areas in which plates approximate, collide, and one of them must subduct under the other one.
The plate that subduces is always the denser and older one. The less-dense plate superpose over the denser one and push it down toward the mantle. At this point, rocky material from the subductive plate melt again.
The correct option is D. a subduction zone.

Cytokines trigger endothelial cells to express specific receptors called selectins, which bind to carbohydrates on the surface of neutrophils.
Cytokines are the proteinaceous structures predominant in cell signaling. They also regulate the growth of immune cells and blood cells. They can also occur in the form of glycoproteins. The example of cytokines are interleukins, interferons, chemokines and Tumor Necrosis Factor (TNF).
Selectins are the transmembrane proteins that span the lipid bilayer only once. They belong to the family Cell Adhesion Molecules. They perform role in processes like inflammation, lymphocyte homing, immunological responses, etc. They are localized on the membranes of endothelial cells, leukocytes and platelets.
