Which words fit into the gaps. They might bind to a membrane protein that is only expressed in lymphocytes. The total magnification of the image results from multiplying the objective magnification by the eyepiece magnification, which normally is 10x. Electron microscopes enable us to look in far more detail at objects than is possible with a light microscope. Download the .zip file and upload it to your LMS.
