Observe microvilli, mitochondria and junctions and other cell structures of the chicken intestine slide. This light is in the 400-700 nm range, whereas fluorescence microscopy uses light with much higher intensity. By infecting the lymphocytes it somehow manages to delay the immune response and the onset of inflammation. The specimen is usually stained and observed while illuminated; useful for observation of the gross morphological features of bacteria, fungi, algae, and protozoa. It is also used to visually enhance 3-D features at small scales. Q4: List MAIN methods in order performed (Or describe if name unknown).

Therefor, we cant see any inflammatory symptoms a few days after infecting the chickens with al three viruses. The emission filter between the dichroic mirror and the camera filters out all other (background) wavelengths. Light from the light source passes through the sample and reaches the objective, which magnifies the sample.
