Microscopy For Microbiology

Microscopy For Microbiology. Please note that I already have all the answers to this lab and the only thing I need is the PICTURES to go with it. I will not adjust the price of this post. Thank you!

I do not have my lab kit as yet and so the MICROSCOPE is what I do not have, so again all I need is the answers to the questions related to the pictures. I need the pictures of the magnified letter. PLEASE DO NOT GOOGLE THIS AND USE THEM, I WILL KNOW!!!!

Lab Reports:

You need to write:

1. Background

2. Procedure- can be in paragraph or step by step format.

3. Answer the Questions at the end.

Lab Report Assistant

This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.
