1. What is magnetic declination? Why is it important to set or check the magnetic declination on a compass whenever you go out into the field to map rock formations? What can happen
if you do not make sure the declination on the compass is set correctly?

it is either c or d and i know for sure it is not a or b

i believe the answer would be b. hope it : )

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
