What is the definition of class class 11 in biology?

What is the definition of order class 11?

What makes some orders class 11 and others not?

Why are these things considered?
The two that I know are: Any monk under 90 is assigned a Buddhism class based on how high. Their spiritual maturity is. Buddhism class 5 is the highest class, but people only make it to 5th for about three years until they start. Attaining Insight at which time they will take the next class. In addition, monks take ordination by paying a fee. They have chosen to serve their community in a certain way, hence the ordination fee. If you have any knowledge to add to this, please do. Just let me know.

Also, if you can give me a link to the text (or an abstract with a url). About ordination fees please let me know.

It's probably referring to a cell classification for the B and T cell subtypes.

The standard is the cell surface marker CDw11 for mouse T cells and CD8alpha for human T cells. It has a specific, stable, unique peptide marker for both subtypes.

The standard is the cell surface marker CDw11 for mouse T cells. (source) CDw11 was first used for the analysis of thymocyte-T cell interactions. It was later determined that the CDw11 antibody recognized an "alpha heavy chain polypeptide". CDw11 was found to be present on most T lymphocytes and on natural killer cells, monocytes, macrophages, granulocytes, and platelets. The antigen was defined as TCR gamma delta but its identification was not completed until a few years later (see below). (source)
T cell alpha/beta antigen (CD3) is composed of eight membrane polypeptides (CD3 epsilon, zeta, eta, gamma, delta, zeta 2, CD3 delta 1 and CD3 delta 2) of varying molecular weights; the most important polypeptides are CD3 delta, CD3 gamma, CD3 epsilon and CD3 zeta. (source) "TCR-receptor" refers to an extracellular part of the signal transduction molecule that is involved in recognizing and binding with specific ligands (ie antigens, which are presented by Major Histocompatibility Complex (MHC) molecules on target cells, which are recognized by CD3 complex (ie one T cell has to recognize a self and non-self cell simultaneously, so the coexistence of self- and non-self specific signals is needed). And CD3 is found on a special part of T cell structure which is composed of many membrane glycoproteins, such as CD3 alpha/beta/gamma and CD4/CD8, etc, which are involved in signal transduction.

Alpha/beta T cell receptor (CD3 gamma delta), which is the standard for beta and gamma () T cells, and it is composed of four proteins: CD3 epsilon, CD3 zeta, CD3 gamma and CD3 delta.
