Q1. The answer is 400x. To calculate the magnification (M), you just need to multiply the objective power (O) and the ocular lens power (OL): M = O * OL It is given: O = 40 times OL = 10 times Thus, M = O * OL = 40 * 10 = 400 Thus, the magnification of the specimen is 400 times. Q2. The answer is transmission electron microscope.A compound light microscope and dissecting microscope are not useful in observing structures inside the cells because they have not as high resolution as a scanning electron microscope and a transmission electron microscope.However, the scanning electron microscope enables to see structures on the surface of the objects and it would not be possible to look at the internal structures of the cell. On the other hand, the transmission electron microscope allows studying a very thin cross-section of the cell. It is best for looking at internal structures of the cell.Q3. The answer is: have higher resolution that allows you to view smaller specimens. The magnification of electron microscopes is up to 1,000,000 times while compound light microscopes have the magnification up to 1,500 times. This means that the electron microscopes allow you to view smaller specimens and provide you higher resolution. Regarding the other choices - they are very expensive and allow you to view only dead specimens in black and white images.
