Explanation / Answer

Ans12: Objective lense is the one which collects light from the object, and produce a real and magnified image of it.

Ans 13: Resolving power of the microscope is it's ability to distinguish two close objects as separate.

Ans 14: Some bacteria are not capable of growin on artificial media, because the various different nutrients and growing conditions needed by some bacteria are not known.

Ans 15: Phase contrast microscopy converts phase shifts in light passing through a transparent specimen to brightness changes in the image. it is reflected as brightness changes in the final image. It works separating the illuminating (background) light from the specimen-scattered light.
