Normal rendering for sound allows playback in mono or stereo through one or two speakers (or equivalent headphones) or, in the case of surround sound, through multiple loudspeakers carefully arranged in a room (or through specialized headphones).
An easy way to remember what e.g. means is to think of it as standing for example given.. Alternatively, just say eg out loud â it sounds just like the first syllable in example. i.e. i.e. stands for id est which means that is.
Immunoglobulins (Ig) are glycoprotein molecules that function as antibodies. Since antibodies are present in the bloodstream or bound to cell membranes, they are considered to be a part of the humoral immune system. During an immune response, immunoglobulins bind to specific antigens (any foreign substance that is capable of inducing an immune response). Examples of antigens include bacteria, viruses, mold spores, dust mites, animal dander and fungus.
