These antibodies are IgD.
It is a monomeric antibody isotype that is expressed in the plasma membranes of immature B-lymphocytes. It is also produced in a secreted form that is found in small amounts in blood serum. IgD is co-expressed with IgM on the surface of the majority of mature B cells prior to antigenic stimulation and functions as a transmembrane antigen receptor.
The first real dissections for the study of disease were carried out about 300 BCE by the Alexandrian physicians Herophilus and Erasistratus, but it was the Greek physician Galen of Pergamum in the late 2nd century CE who was the first to correlate the patient’s symptoms (complaints) and signs (what can be seen and felt) with what was found upon examining the “affected part of the deceased.” This was a significant advance that eventually led to the autopsy and broke an ancient barrier to progress in medicine.
The <em>correct</em> answer is:
Penicillium
Aspergillus
The lesson states:
If you've ever heard of or taken penicillin to fight off an infection, you can thank a member of the imperfect fungi called penicillium. Some mold species of penicillium are also important in the flavoring and aging of cheese. Roquefort and Camembert cheese owe their distinctive flavors to these fungi. Aspergillus is an imperfect fungus that is found on decaying food. It also contributes to the production of organic acids like citric acid. <u>Both penicillium and aspergillus produce enzymes that are purified and used in various industrial compounds and in medicine.</u>
