The major histocompatibility complex (MHC<span>) is a set of cell surface proteins essential for the acquired immune system to recognize foreign molecules in vertebrates, which in turn determines histocompatibility. ... The human </span>MHC<span> is also called the </span>HLA<span> (human leukocyte antigen) complex (often just the </span>HLA<span>).</span>
I think the correct answer from the choices listed above is option b. A permeable rock weathers easily because it <span>contains many small, connected airspaces. Its porosity is very high that it can easily be destroyed by simple means. Hope this answers the question.</span>
