In the histologic specimen of loose irregular fibrous connective tissue stained with methyl blue pyronin one can see that some cells contain pyroninophilic cytoplasm, and close to the nucleus in each of the cells there is clearing? What do we call those cells? What function does it perform?

Jessica was in the hospital for an extended period with a severe respiratory infection. During that period she received multiple IM injections and was discharged with orders to continue the injections daily until the doctor advised her to discontinue them. The nursing staff had been injecting the medication into the gluteal area, but this area was becoming sore from all of the prior injections. What options might she use for the future to avoid pain in the area of the injections?

1. Create a “formula” for the process you used above, such that you’d be able to determine the field of view for a lens of any magnification if you knew the field of view of another lens magnification on the same microscope.
2. Using your answers from the previous two questions, estimate the size -- in microns -- of an organism if it covered one-third of the field of view at 100X total magnification. Show your work/process.

Using a peer reviewed journal source, find a current microbiology topic and post a two paragraph review that includes a question to be discussed by your classmates. Please include a link to the journal article.  

Our imaginary UR Critters include Herbimonas wegerii, Marsulphromonas davisius and Adphytus melhartii. Which one(s) have photosynthetic pigments / cilia (flagella) / "eye spots?" 

1. Use the four "observation type" examples listed above to describe the UR Critters.
2. Which UR Critter(s) might be able to detect light? Why do you think this?
3. Which UR Critter(s) might be able to move? Why do you think this?

A good place to start when making observations of both microscopic and macroscopic organisms is:

• size (measure this),
• general cell/body shape,
• color and texture and,
• interesting or unique features

The world is currently experiencing one of the most devastating pandemic in modern history. This pandemic is caused by a virus known as corona virus and the disease is referred to as COVID-19. A lot of conspiracy theories and speculations have since emerged and are being spread everywhere. Identify some of the major conspiracy theories and false information regards COVID-19 and argue scientifically why such information is not correct.

You use phase contrast microscopy to observe a wet mount of a soil sample (the fi rst picture below) and a “goo” sample (the second image below) from the ELVIS. In what ways are the potential ET microbes similar to microbes previously characterized on Earth? In what ways are they diff erent? How could you determine whether the microbes present in the soil or goo samples are phylogenetically similar or distant from known microorganisms on Earth?

1. Are the antibiotic producing isolates sensitive to known antibiotics? 2. If so, what does this tell us about the isolates? How might this relate to the antibiotics they produce?
