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.

- You 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_forwardUse the following tree diagram to answer Questions #8-10. 8) Which of the following two animals are the most closely related based on the tree to the left? a) Pig and camel b) Hippo and pig c) Deer and cow 9) CIRCLE on the tree diagram where the common ancestor between a hippo and a cow is. 10) Put a SQUARE on the tree diagram where the common ancestor between a pig and a peccary is.arrow_forwardExplain: Healthy Cell Function Overview→ Briefly describe how a healthy cell usually works: metabolism (ATP production), pH balance, glycogen storage, ion transport, enzymes, etc. Gene Mutation and Genetics Part→ Focus on the autosomal recessive mutation and explain: How gene mutation affects the cell. How autosomal inheritance works. Compare the normal and mutated gene sequences simply. → Talk about possible consequences of a faulty hydrolytic enzyme.arrow_forward

Sucralfate comes as a 1 gm tablet, famotidine as 20 mg tablets, and doxycycline as 100mg tablets. All are in bottles of 100 tablets.How many total mg are needed for the patient and how many tablets of each would be needed to provide each dose?How many bottles of each would be needed to have available if this patient were to be on this drug regimen for 5 days?arrow_forward
