Hi, everyone:I am taking A&P I, the second lab is using the microscope to prepare smears. I am really confused with some of the questions here. I've already spend a whole day studying the lab manual and answered most of the other questions.In genegral, at what position should the condenser be kept? --- Is it erect? I'm not sure.The 45X and 100X objectives have shorter working distances than the 10X objective.-- I think it is true. The working distance is the distance between the objective lens and the specimen.When chaning from low power to high power, it is generally necessary toA. Open the diaphragmB. Close the diaphragmIs the correct answer A, so more lights will be let in?Anybody can give me a hint on these?
