What is the purpose of immersion oil in brightfield microscopy? Answer choices 1. With a lower refractive index than the specimen, oil increase image contrast and "d" resolution limit of Abbe's eqn. 2. With a higher refractive index than the specimen, oil improves image contrast and increases "d" resolution limit of Abbe's eqn. 3. With a lower refractive index than air, oil improves image resolution (decreases "d" resolution limit of Abbe's eqn). 4. With a similar refractive index as the specimen, oil improves image contrast and decreases "d" resolution limit of Abbe's eqn. 5. With a higher refractive index than air, oil improves image resolution (decreases "d" resolution limit of Abbe's eqn).(right answer) Cheek cells from individual students were treated with DAPI (4',6-diamidino-2-phenylindole) in order to… Answer choices 1. chemically "fix" the cellular components in situ. 2. increase contrast for enhanced viewing. 3. allow
