A. Describe a good technique for withdrawing samples using a variable automatic micropipette? b. How does a pipetting excerise help one to understand the importance of accurate pipetting using microliter volumes?
c. Why would practicing pipetting samples with various viscosities be useful?

c

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

request for reexamination

its probably to later but whats the question
