The smear is stained with a special dye, which helps tell the difference between various types of white blood cells. Five types of white blood cells, also called leukocytes, normally appear in the blood: 1  Neutrophils.  Lymphocytes (B cells and T cells)
What type of plate boundary leads to subduction? Convergent plate boundaries lead to subduction. Subduction occurs  when one tectonic plate rides over the edge of another tectonic  plate which sinks into the mantle as theyâ¦ converge.
There are three main types of plate boundaries: 1. Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. The denser plate is subducted underneath the less dense plate.The plate being forced under is eventually melted and destroyed.i.here are three main types of plate boundaries: 1.
