Astudent observed a stained specimen of bacteria using bright-field microscopy. at 100x magnification, there appeared to be only one cell in the field of view, but at 1000x it was clear that there were two cells close together. the ability to distinguish these two cells as separate entities is called
a. wavelengthb. cell divisionc. magnificationd. resolution

d. resolution

Explanation:

Resolution is a term that refers to the ability to distinguish two objects whose images are very close, in the case of the above question the resolution refers to the ability to perceive two cells that are very close together. In other words, resolution refers to the visualization of two observed objects with relatively small angular separation.

i think it is dna, i'm not totally sure but i think it might be.
