Autoimmunity. The immune system is a complex set of organs, cells, proteins and other substances that function to prevent infection. Primary immunodeficiency diseases are characterized by abnormalities in specific components of the immune system that lead to an increased susceptibility to infection.
How to Measure Ounces. Ounces are a measurement of mass or weight, and as such, you should use a scale when measuring ounces for a recipe, experiment, or similar procedure. In contrast, fluid ounces are a measurement of volume, so they are measured in a different manner. Note that there are also ways to estimate mass in ounces if precision is not necessary, and if required, you can easily convert a few other units of measurement into ounces.
Duddy Alidia answered on 4/12/2014. An ounce is a unit of measuring weight as well as liquid volume (fluid ounces). As it happens, a pint of sour cream also weighs 16 ounces. An ounce in net weight should not be confused with an ounce in volume. While 16 fluid ounces of water does have a net weight of 16 ounces, 16 fluid ounces of molasses, however, is more dense and actually weighs 24 ounces.
