Professor tan studies water quality in streams near chemical plants. which is a type of qualitative data that professor tan should record during these studies?

cuz he is really really short, assuming an unorthodox and inherently unlucky configuration of elevator buttons…

explanation:

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
