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.
Logarithm. The logarithm of a number N to the base a is the exponent m to which a (base of the logarithm) must be raised in order to obtain N (denoted by log a N). Thus m = log a N if am = N. For example, log 10 100 = 2, log 2 (1/32) = â5, and log a 1 = 0 since 100 = 10 2, 1/32 = 2 â5, and1 = a 0.
