Practice question
Question
What will be value of the Numerical Aperture (NA), if half aperture angle is 58° and oil immersed objective is used for the process of light microscopy? (Answer up to 1 decimal place) Consider Sin 58° = 0.85 and refractive index of immersion oil used is = 1.50. (NAT)
Explanation
In general biology, core biological organization dictates that structure-function relationships govern cellular processes. Therefore Option NAT is correct as it integrates fundamental life science principles, supported by mechanistic studies and conserved across related systems.
