Which of the following is/are TRUE 1. regarding microscopes? * Which of the following is/are TRUE 2. regarding the use of laboratory glass wares and instruments? * Brightfield microscopes, a compound microscope, can be used to examine stained and unstained specimen. Both the inoculating loop and inoculating needle can be used in nutrient broth. AFM uses a diamond and a metal probe that scans surfaces of a specimen A serologic pipette has a bulbous part which is used to deliver different volumes of liquid. Darkfield microscope has an opaque disc which brightens the light that would enter A glass slide and coverslip are to observe the lenses. stained microorganisms. 4.

I need help with a microbiology question comparison of the 3 types of microscopy including which shows more detail, which is clearer, and explain which would be preferred when observing paramecium. The three types of microscopy that were used to view paramecium were brightfield,darkfield, and phase-contrast microscopes. Thank you!

Tell me three things about how cultures are handled in a clinical laboratory.
