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.
Using Logarithms. The above method can be stated another way: the number of bits is the exponent of the smallest power of two greater than your number. log2(n) means the logarithm in base 2 of n, which is the exponent to which 2 is raised to get n. For example, log2(123) â 6.9425145.
