Witch one would it be

A. Pick up the shattered glass

B. Clean the substance with a paper towel

C. Inform her teacher or lab instructor

D. Ask her lab partner to clean it up

The answer to your question is the letter C.

Explanation:

As it is mentioned in the description, Megan does not know what substance is inside the pipette. If we do not know what substance is, the first thing that we must do is to inform the teacher of the lab assistance to support us because it  could be a dangerous substance that could harm us if we touch it.

Also, the teacher could inform us how to handle that substance because it could require a special handle before place it in the trash.

The answer is C.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
