Microbiology Lab Test, Micro lab 1 Exam Questions and Answers Why are thick or dense smears less likely to provide a good smear preparation for microscopic evaluation? -Answer-It will diminish the amount o flight that can pass through making it difficult to see under the microscope. Why is it essential that smears be air-dried? Why can't they be gently heated over the flame to speed up the drying process? -Answer-1. Overheat will denature and rupture the cell wall. 2. excess water on the...
