TRUE or FALSE only! 1. Microscopes are necessary for biological investigations because it allows us to study the detailed structures of an organism. 2. Microscopes must be handled with care and should be carried with both hands, one under the base and one at the objectives. 3. If you are tasked to mount a specimen of a head louse and view its overall morphology the best lens to use is the oil immersion objective lenses. 4. Objective lenses initially magnify the object’s image, form the real image and concentrate and send light rays to the condenser.
