A slide of human blood cells was observed in focus under the low-power objective of a compound light microscope was switched to high power the image was dark and fuzzy. Which parts of the microscope should be used to correct this situation

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

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you

cells spend most of their time in interphase

i won't lie i don't know so go online and ask google thats what i do
