Fig. 2.1 shows photomicrographs of lung tissue at the same magnification. One shows healthy lung tissue and the other shows lung tissue from a person with COPD.  Line AB shows the diameter of one healthy alveolus. Line CD shows the diameter of an area of lung where the alveoli have been destroyed. The real diameter of healthy alveolus is 200 µm. If line AB in the picture is 2 cm, calculate the magnification of the picture......   Magnification: …………………… please solve with step max 15-
