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.
One pound (abbreviated as lb.) is equal to 16 ounces. It is hard to overlap or connect the measurements of a fluid ounce (volume) to an ounce (weight). This means that it is not possible to immediately determine the weight of a certain matter only from a given volume, per se.
