As per figures the the bacteria is not retaining the gram stain and it stained red by acid fast with catalase positive indication. so
1. Based on the above observations the bacteria belongs to mycobacterium group.
2. The shape of the unknown is rod shaped
3. The unknown is not stained by gram stain
4. As it belongs to the mycobacterium and gram positive, the cell wall is thick with mycolic acid in its peptidoglycan layer.

can you please answer all the questions
You have been given another unknown and the Gram stain results revealed Gram positive rods. Your TA now tells you that you should inoculate your unknown into a TSB broth to be incubated at 65 degrees C for 24 hr. and to streak it onto a TSA plate for isolation. The TSA plate is incubated at 35-37 degrees C for 24 hr. It will then be used to do further inoculations of your...

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
