Sign in to the MediaLab. website (using your username and password that you received from the Program Director) and complete a 50-question test with Blood Bank.   Go to ‘selected areas’ and check the Blood Bank box (to include all areas under the Blood Bank section).   This exam is proctored. You must score at least 75%.

There is nothing to submit.

Bohr stated that the structure of an atom had specific energy levels in which the electrons were located around the nucleus. Whenever an electron moves from one of these energy levels to another it must either gain or lose some energy. If the electron gains energy this is called an absorbance and if it lost energy this is called an emittance. In both cases an energy particle called a ______________ is created.
