13. Practice Calculations: 3 colonies were suspended in the following dilution series and then a
viable plate count and microscope count was performed. Calculate IDF's, TDF's and then
calculate the CFU/mL in each tube by both methods. Finally calculate the cells in 1 colony by
both methods. Show all of your calculations in the space provided on the following pages.

Can you tell…arrow_forwardYou have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
