The white blood cells then produce antibodies to match the shape of the antigens. The antigens on the surface of pathogenic cells are different from those on the surface of your own cells. This enables your immune system to distinguish pathogens from cells that are part of your body.he white blood cells then produce antibodies to match the shape of the antigens.

The first view is a good way to start thinking about logarithms: logarithms are exponents. That's the view introduced in this section. Another view is that logarithmic functions âundoâ exponential functions, or (more briefly) logs âundoâ exponents. and is the subject of more advanced lessons.
Recall that a logarithm is just the power to which a base is raised to equal a particular number. The definition of a logarithmic scale is one in which the units on the axis are powers, or logarithms, of a base number, and it is typically used when the increase or decrease in value on that axis is exponential.
