I believe that the most common antibody switch is from IgM to IgG.
Class switching occurs by a mechanism called the class switch recombination binding. It is a biological mechanism that allows the class of antibody produced by an activated B cell to change during a process known as isotype or class switching. The mechanism changes a B cell's production of antibodies from one form to another, such as from the isotype IgM to the isotype IgG.
Answer:
1.fungi, 2.fungi 3.monera 4.fungi 5. protista 6. animalia
Explanation:
since, yeast is a fungus , penicilium and mushroom (agaricus) also fall under this catergory due to the <em>presence of mysceliom and hyphae.</em>
rizobium is a <em>bacteria</em> so falls under the kingdom monera
