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.
Common Logarithms: Base 10. Sometimes a logarithm is written without a base, like this: log(100). This usually means that the base is really 10. It is called a common logarithm. Engineers love to use it. On a calculator it is the log button.It is how many times we need to use 10 in a multiplication, to get our desired number.xponents and Logarithms are related, let's find out how ... The exponent says how many times to use the number in a multiplication. In this example: 23 = 2 Ã 2 Ã 2 = 8. (2 is used 3 times in a multiplication to get 8).
